For an alias without a model version, users then get that model's **Effort** control, and sessions assume that model's context window. Requires Claude Desktop 4.29.0 or later. For an alias that contains a model version, see [Map an unrecognized model ID to a Claude model](https://claude.com/docs/third-party/claude-desktop/models.md#map-an-unrecognized-model-id-to-a-claude-model). + Your gateway can mark which Claude tier a model serves by returning an `anthropic_family_tier` field (a tier name such as `sonnet` or `opus`) on that model object in its `/v1/models` response, optionally with `is_family_default: true` when several models map to the same tier. The app uses the marked model when it needs that tier, for example to resolve a bare `sonnet` alias. The app also reads other optional fields on each model object. `display_name` sets the picker label when the app cannot derive one from the model ID. `description` adds a one-line description beneath the label (Claude Desktop 1.49585.0 or later). `supports_1m: true`, or a `max_input_tokens` value of 1,000,000 or more, marks a discovered model as supporting the 1M-token context window, as `supports1m` does on an `inferenceModels` entry. If your gateway does not implement `GET /v1/models`, give every `inferenceModels` entry the full model ID your gateway accepts; bare tier aliases such as `sonnet` rely on discovery to resolve. When every entry is a full model ID, the app skips the `/v1/models` call automatically.

Fine-tuning and RLHF are used to refine these pretrained models, making them more useful for a wide range of tasks. ## RAG (retrieval augmented generation) -Retrieval augmented generation (RAG) is a technique that combines information retrieval with language model generation to improve the accuracy and relevance of the generated text, and to better ground the model's response in evidence. In RAG, a language model is augmented with an external knowledge base or a set of documents that is passed into the context window. The data is retrieved at runtime when a query is sent to the model, although the model itself does not necessarily retrieve the data (but can with [tool use](https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview) and a retrieval function). When generating text, relevant information first must be retrieved from the knowledge base based on the input prompt, and then passed to the model along with the original query. The model uses this information to guide the output it generates. This allows the model to access and use information beyond its training data, reducing the reliance on memorization and improving the factual accuracy of the generated text. RAG can be particularly useful for tasks that require up-to-date information, domain-specific knowledge, or explicit citation of sources. However, the effectiveness of RAG depends on the quality and relevance of the external knowledge base and the knowledge that is retrieved at runtime. +Retrieval augmented generation (RAG) is a technique that combines information retrieval with language model generation to improve the accuracy and relevance of the generated text, and to better ground the model’s response in evidence.

This can include helping the model follow instructions more effectively or act more like a chatbot. Human feedback consists of ranking a set of two or more example texts, and the reinforcement learning process encourages the model to prefer outputs that are similar to the higher-ranked ones. Claude has been trained using RLHF to be a more helpful assistant. For more details, you can read Anthropic's [paper on RLHF](https://arxiv.org/abs/2204.05862). +Reinforcement learning from human feedback (RLHF) is a technique used to train a pretrained language model to behave in ways that are consistent with human preferences.

Higher temperatures lead to more creative and diverse outputs, allowing for multiple variations in phrasing and, in the case of fiction, variation in answers as well. Lower temperatures result in more conservative and deterministic outputs that stick to the most probable phrasing and answers. Adjusting the temperature allows users to encourage a language model to explore rare, uncommon, or surprising word choices and sequences, rather than only selecting the most likely predictions. +Temperature is a parameter that controls the randomness of a model’s predictions during text generation.

It is an important indicator of the model's responsiveness and is particularly relevant for interactive applications, chatbots, and real-time systems where users expect quick initial feedback. A lower TTFT indicates that the model can start generating a response faster, providing a more seamless and engaging user experience. Factors that can influence TTFT include model size, hardware capabilities, network conditions, and the complexity of the prompt. +Time to first token (TTFT) is a performance metric that measures the time it takes for a language model to generate the first token of its output after receiving a prompt.

For Claude, the number of characters a token represents depends on the model and the language. Claude 4.7 and later models and Claude Mythos Preview use a newer tokenizer that produces approximately 30 percent more tokens for the same text than earlier models, on which a token represents approximately 3.5 English characters. To get exact counts, use [token counting](https://platform.claude.com/docs/en/build-with-claude/token-counting) with the model you plan to use. Tokens are typically hidden when interacting with language models at the "text" level but become relevant when examining the exact inputs and outputs of a language model. When Claude is provided with text to evaluate, the text (consisting of a series of characters) is encoded into a series of tokens for the model to process. Larger tokens improve data efficiency during inference and pretraining (and are used when possible), whereas smaller tokens allow a model to handle uncommon or never-before-seen words. The choice of tokenization method can impact the model's performance, vocabulary size, and ability to handle out-of-vocabulary words. +Tokens are the smallest individual units of a language model, and can correspond to words, subwords, characters, or even bytes (in the case of Unicode).

At `xhigh`, it consulted on 3 of the 20 problems without the prompt and 4 with it, each time on its attempts with the most turns. + * **Advisor, Claude Sonnet 5.5 consult check:** The Claude Sonnet 5.5 consult check cited in [Advisor strategy](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#advisor-strategy-escalate-hard-decisions) ran one attempt on each of 20 of the 478 problems, on September 24, 2026, with a Claude Opus 5.5 advisor through the advisor tool. Four configurations ran: `high` and `xhigh`, each with and without the advisor tool documentation’s suggested system prompt for coding tasks. At its default effort, `high`, Claude Sonnet 5.5 did not consult the advisor on any of the 20 problems, with or without the prompt. At `xhigh`, it consulted on 3 of the 20 problems without the prompt and 4 with it, each time on its attempts with the most turns. * **Escalation figures:** Escalation figures come task by task from the Opus 5.5 runs: `low` first, then `high` on its failures, solved 96.4% to 97.5% across run pairings for about $0.17 USD; `medium` first, 96.0% to 97.1% for about $0.24 USD; `high` re-run on its own failures, 96.9% for $0.31 USD; everything at `high`, 94.8% to 95.8% for $0.29 USD. - * **Compare models:** The Claude Fable 5.1 figure in [Compare models](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#compare-models-on-cost-per-task) comes from one run on the same subset at the default effort, run August 26, 2026: counted over the 478 problems, it solved 92.3% for $1.19 USD per solved task. That section's chart and its Claude Opus 5.5 and Claude Sonnet 5.5 figures pool the two runs at each setting plotted, all counted over the 478 problems: Claude Opus 5.5 at `low`, `medium`, and `high`, and Claude Sonnet 5.5 at `medium` and `high`. - * **Compare models, work per task:** In those figures, Claude Opus 5.5 at `low` did less work on each task than Claude Sonnet 5.5 at its default: a little over half of Sonnet 5.5's output tokens and a little over a third of its cache reads. At their defaults, Opus 5.5 at `medium` solved about 5 percentage points more than Sonnet 5.5 for about twice the cost. At that setting it did slightly more work per task than Sonnet 5.5. - * **Upgrade the model, runs:** The Claude Fable 5 point in Upgrade the model pools three runs at the default effort, run August 26, 2026, priced as a customer's organization is metered. The upgrade ladder counts every model over the 478 problems, each at its shipped defaults. It uses one run per model except Opus 5, Opus 5.5, Sonnet 5, and Sonnet 5.5 (two runs each) and Fable 5 (the three runs described above). The Opus 4.7, Opus 4.8, Sonnet 4.6, and Sonnet 5 runs ran August 17 to 19, 2026, and the Opus 5 runs on August 4, all in one harness and organization; the Opus 5.5 and Sonnet 5.5 runs are the ones described earlier in this reference. - * **Upgrade the model, cost per solved task:** Claude Opus 5 costs 21% more per solved task than Claude Opus 4.8 when those Claude Opus 5 runs are compared with one Claude Opus 4.8 run at its shipped defaults from the August 17 to 19 series, counted over the same 478 problems; the chart's SWE-bench Pro panel shows neither Claude Opus 4.7 nor Claude Opus 4.8. In the same measurements, priced as a customer is billed, Claude Opus 5 solves 12 more points of tasks than Claude Opus 4.8 at that 21% more per solved task, Claude Opus 4.8 solves the same share of tasks as Claude Opus 4.7 for 14% less per solved task, and Claude Opus 5 at `low` effort beats Claude Opus 4.8's default on this benchmark for about 30% of its cost per solved task. - * **Upgrade the model, prices:** Claude Sonnet 5's saving over Claude Sonnet 4.6 in Upgrade the model comes from its lower per-token price, which more than offsets the extra tokens it uses per task. Claude Sonnet 5.5 charges the same as Claude Sonnet 5 for everything but cache reads, which cost half as much. Claude Opus 5.5's token prices are lower than Claude Opus 5's, most of all for cache reads. Like Claude Sonnet 5, the frontier tier gained through price: most of Claude Fable 5.1's saving is the lower cache-read price. + * **Compare models:** The Claude Fable 5.1 figure in [Compare models](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#compare-models-on-cost-per-task) comes from one run on the same subset at the default effort, run August 26, 2026: counted over the 478 problems, it solved 92.3% for $1.19 USD per solved task.

Every configuration ran on Claude Managed Agents. The charted team configuration is one in which the Claude Fable 5.1 orchestrator ran the whole sweep inside the platform at its documented limit of 25 concurrent Claude Sonnet 5 workers, run August 30, 2026; its three runs scored F1 0.764, 0.825, and 0.791 after the extras audit (raw 0.751, 0.821, and 0.781) for $225 USD, $234 USD, and $283 USD.

The 6-minute figures leave out run 3, in which 2 of that session's 39 keep-alive requests timed out: the cache expired before those two turns, the session wrote 214,000 tokens to the cache against 80,000 to 85,000 in runs 1 and 2, and it cost 38% more than run 3's 1-hour session. - * **Keep-alive requests, Claude Sonnet 5.5, by run:** Comparing each run's keep-alive session with the same run's 1-hour session instead, keep-alive cost from about the same to 10% more at 6 minutes (runs 1 and 2; 4% more on their average), from about the same to 16% more at 20 minutes, and 64% to 80% more at 45 minutes. - * **Keep-alive requests, Claude Sonnet 5.5, sample size:** The keep-alive chart's 6-minute points average runs 1 and 2 for all three settings. Each cell is three sessions (two for the 6-minute figures above). With no pauses, keep-alive sends no extra requests and so matches the 5-minute setting, yet the two differed by as much as 23% within a single run, so a difference of a few percent in a three-run average is not a clear effect. + * **5-minute and 1-hour settings, Claude Sonnet 5.5:** With 5% of turns paused the 5-minute setting cost 5% more than the 1-hour setting on average (2% less to 12% more across the three runs), which is within run-to-run variation: that draw’s pauses fell on small prefixes, as on Claude Sonnet 5, and re-billing each 5-minute session’s own tokens at 1-hour cache prices gives about 1% more. With 10% paused it cost 54% more (36% to 73% more). With no pauses, the 5-minute setting cost 19% less than the 1-hour setting on average (3% to 32% less across the three runs; the 1-hour setting’s higher write price predicts about 20%), and 21% to 24% less in every run with 2-minute pauses. + * **Keep-alive requests, Claude Sonnet 5.5:** Keep-alive requests cost 16% less than the 1-hour setting on average with 5% of turns paused (13% to 20% less across the three runs) and 8% less with 10% (3% to 10% less), and cost more with a pause of 6 minutes or more before every turn.

Each of these three sessions is one conversation of 40 requests over the job's 20 issues. At list prices as of October 12, 2026, the sessions cost $0.51 USD each on average, from the usage fields, against $3.70 USD with every input token at the input price and output tokens unchanged: a saving of 86% (86% to 87% across the three sessions), or a factor of 7.3. At the launch cache-read price of $0.20 USD the saving is 82%, so the rise over the Claude Sonnet 5 figure comes from the lower cache-read price. + * **Priced from recorded token counts, Claude Sonnet 5.5:** Anthropic also re-priced the recorded token counts of the three Claude Sonnet 5.5 sessions with the 5-minute cache and no pauses for the caching figure in [Why caching comes first](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#why-caching-comes-first).

At the launch cache-read price of $0.20 USD the saving is 82%, so the rise over the Claude Sonnet 5 figure comes from the lower cache-read price. * **Priced from recorded token counts, Claude Opus 5.5:** Re-priced the same way, the three Claude Opus 5.5 sessions at its default effort, `medium`, with the 5-minute cache and no pauses cost $1.02 USD each on average against $6.93 USD, a saving of 85%, or a factor of 6.8; the model used thinking in 79% of requests. - * **How thinking was set, two sets of runs only:** The requests of the three Claude Sonnet 5.5 sessions with the 5-minute cache and no pauses set no thinking option, so thinking was left at the model's default, and the model used it in 38% of requests. The requests of the Claude Sonnet 5 runs with caching off and with caching on also set no thinking option, so thinking was left at the model's default, and the model used it in 41 of 121 requests with caching off and 40 of 120 with caching on. + * **How thinking was set, two sets of runs only:** The requests of the three Claude Sonnet 5.5 sessions with the 5-minute cache and no pauses set no thinking option, so thinking was left at the model’s default, and the model used it in 38% of requests.

The conversations held about 5,000 or 100,000 tokens of filler text, with fixed one-word assistant turns and no thinking blocks. In a conversation cached at 5 minutes, the first 1-hour request that added a turn read nothing and wrote the whole prompt at the 1-hour price (55 of 55). The next 1-hour request read everything (36 of 36). A system prompt cached at 1 hour from the first request was still read (12 of 12). A 1-hour request that added nothing read the 5-minute entries (31 of 31) and did not extend them: 8 minutes later, the same request read nothing (12 of 12). In a conversation cached at 1 hour, a 5-minute request read everything and wrote only its new turn (12 of 12). The requests ran in one Anthropic-internal organization on the Claude API. * **Changing the duration mid-conversation, how priced:** From the `usage` fields at list prices, at just over 100,000 tokens, with `max_tokens` at 16, the first 1-hour request that added a turn cost $2.01 USD, $0.80 USD, $0.40 USD, and $0.10 USD on the four models in the order named. A turn that read the cache cost $0.026 USD, $0.020 USD, $0.010 USD, and $0.005 USD.

Once one request had cached the conversation, a second added one short turn, and each measured request sent that longer conversation with one change.

Once one request had cached the conversation, a second added one short turn, and each measured request sent that longer conversation with one change. Two conversations per model gave the same result. * **October 2026 test, tokens read and written:** With no change, and with a per-message effort change, the request read all 101,000 tokens and wrote none. With a 25-token mid-conversation system message, or a 25-token status line at the end of the newest user turn, it read them all and wrote only the new text. A top-level effort change (to `low` on Claude Fable 5.1 and Claude Sonnet 5.5, to `high` on Claude Opus 5.5 and Claude Haiku 5.5) read the 20,000-token system prompt and wrote 81,000 tokens. The same 25 tokens at the front or the end of the system prompt read nothing and wrote all 101,000. The request after a mid-conversation system message, a top-level effort change, or 25 tokens added to the end of the system prompt read the new prefix; a new status line at the front wrote everything again. A further test on October 21, 2026, on the same four models with conversations of 5,000 tokens, and on all but Claude Fable 5.1 with conversations of 100,000 tokens, all with one-word replies, sent a beta header for the first time mid-conversation, as a first per-message effort change may: that request read everything the request before it had cached, all 54 times. A system message sent with no beta header did the same, all 15 times. - * **October 2026 test, how priced:** The chart gives the prompt side of one request, from its `usage` fields at list prices. The chart's values, in the order system prompt edit, system message, top-level effort change, and per-message effort change: Claude Fable 5.1 $1.26 USD, $0.026 USD, $1.02 USD, and $0.025 USD; Claude Opus 5.5 $0.50 USD, $0.020 USD, $0.41 USD, and $0.020 USD; Claude Sonnet 5.5 $0.25 USD, $0.010 USD, $0.20 USD, and $0.010 USD. The unchanged request repeated an earlier request byte for byte; a new turn of about 25 tokens adds under $0.001 USD. On Claude Haiku 5.5, whose requests were over 100,000 prompt tokens and so at its [long context prices](https://platform.claude.com/docs/en/about-claude/pricing#long-context-pricing): $0.063 USD for the system prompt edit, $0.052 USD for the effort change, and $0.005 USD for the read.

On accounts created on or after August 31, 2026, 00:00 UTC, a request to one of these four models that sends earlier thinking blocks back gets a 400 error by default if it changes `system`, `tools`, or a message before one of them. - * **What was measured:** The triage agent's long variant from [Trim input and context tokens](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#trim-input-and-context-tokens), run August 24, 2026, on Claude Sonnet 5 with the 5-minute cache, cost from the usage fields at list prices, five sessions per arm: a no-change arm at the default effort throughout ($0.81 USD per session), and two arms that start at low effort and make the same two cache-breaking changes, a switch to the default effort and one added tool, either mid-session at requests 12 and 17 ($0.95 USD) or together on the first request after the first compaction ($0.75 USD). - * **Fourth arm:** A fourth arm of six sessions, run August 25, 2026, made the same two changes on the request that triggered the first compaction ($0.92 USD per session): that request's summarization pass wrote the 81,000-token context to the cache instead of reading it, so that pass cost $0.21 USD against $0.04 USD for the same pass in the boundary arm. - * **Compaction:** Sessions first compacted at request 21 to 25 (16 of the 21 sessions at request 22), once the prompt passed the 80,000-token compaction trigger, and two no-change sessions compacted a second time near the end. The boundary arm's lower total than the no-change arm reflects its low-effort requests before the change and those second compactions rather than caching: the two arms' re-write costs differ by under $0.01 USD. + * **October 2026 test, how priced:** The chart gives the prompt side of one request, from its `usage` fields at list prices.

The boundary arm’s lower total than the no-change arm reflects its low-effort requests before the change and those second compactions rather than caching: the two arms’ re-write costs differ by under $0.01 USD. * **Mid-session arm:** The mid-session arm paid $0.23 USD per session in cache re-writes; the difference between the mid-session and boundary arms was $0.20 USD with a 95% confidence interval of $0.11 USD to $0.29 USD. In the mid-session arm, the effort change and the added tool rewrote 39,000 and 60,000 cached tokens. One of its sessions ran cheap ($0.82 USD) after its model mis-called the search tool following compaction and got empty results; it is included, and without it the arm averages $0.98 USD. * **Accuracy and cache reads:** Accuracy averaged 14.2 of 20 labels in each August 24 arm and 14.7 in the August 25 arm; cache reads were 91% of prompt tokens with no changes, 85% mid-session, 91% at the boundary, and 86% with the changes on the triggering request. * **Separate measurement, status line:** A separate measurement on the 20-issue triage job from [Trim input and context tokens](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#trim-input-and-context-tokens), run August 18, 2026, also on Claude Sonnet 5 with the 5-minute cache, priced the same way, three runs per arm: with a 25-token status line at the front of the system prompt, a run cost $4.24 USD on average ($4.12 USD to $4.47 USD across the three runs) and read nothing from the cache; with the same line at the end of the newest user turn, after the last cache breakpoint, a run cost $0.59 USD ($0.55 USD to $0.61 USD). The first is more than the same job cost with caching off. A later re-run with the same configuration gave $4.28 USD and $0.61 USD. - * **Compaction trigger on Claude Haiku 5.5:** Measured October 21, 2026, on the Messages API with [compaction at a token threshold](https://platform.claude.com/docs/en/build-with-claude/compaction-threshold), no tools, adaptive thinking, the default effort (`medium`), the 5-minute cache, a cache breakpoint on the system prompt, and [automatic caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching#automatic-caching). Each session was one conversation of 45 requests: a 5,000-token system prompt, 10,000 tokens of filler text with every user turn, and one-word assistant turns, except that a reply with a compaction block was sent back whole. Four settings ran three sessions each: triggers of 150,000 tokens (the default), 90,000, and 50,000 (the lowest allowed), and no compaction. Costs within a setting agreed to within 4%. With the default trigger, 15 of each session's 45 replies and all 3 summaries had prompts over 100,000 tokens. With a trigger of 90,000, the largest prompt held 97,269 tokens. Compaction ran at the first request whose whole prompt had reached the trigger, counting the system prompt, cache reads, and cache writes. The summary was written from that prompt plus 44 tokens, up to 7,269 tokens over the trigger. Three more sessions, with a 22,000-token system prompt and a trigger of 50,000, showed that the system prompt counts. The summaries were short (184 to 640 output tokens) because the text was filler.

Schedules: no pauses, 10% of turns, and every turn at 6 minutes on all 20 issues, and 45-minute pauses on the 5-issue subset; three runs per cell (six for the August 26 keep-alive cell with 45-minute pauses), cost computed from each response's `usage` fields at list prices, accuracy against the same gold labels (12 to 18 exact labels of 20). Per-session means on August 26 for the 5-minute, 1-hour, and keep-alive settings: no pauses $2.42 USD, $3.09 USD, $2.29 USD; 10% paused $4.50 USD, $2.96 USD, $2.36 USD; every turn $22.89 USD, $3.01 USD, $2.62 USD; the August 23 cells agree within 6%. The 45-minute figures ($1.68 USD, $0.59 USD, and $0.71 USD per 5-issue session) are from later sessions of August 26: that day's first set of sessions was cut off when its machine was shut down, and the second was affected by a fault in the service and is set aside. The third set gives the 5-minute and 1-hour figures; its three keep-alive sessions sent each keep-alive request once, lost requests to rate-limit refusals, and are not in the mean. The keep-alive figure is the mean of six further sessions that sent any refused keep-alive request again within two seconds. The August 23 runs gave $1.67 USD, $0.58 USD, and $0.70 USD. The break-even between the 5-minute and 1-hour settings is 3.1% of turns, the same measure as reference 16. Claude Fable 5.1's cache read costs 0.025x the input price while its cache writes keep the standard multipliers, so a keep-alive request that re-reads the prefix is cheap and the 1-hour duration's write premium is the larger bill, except with 45-minute pauses, where the keep-alive requests cost more than the premium. +19. **Cache duration measurement on Claude Fable 5.1:** The same 20-issue triage job and harness as reference 16, with `max_tokens` raised to 4,096, run August 23 and August 26, 2026, on the Claude Fable 5.1 launch snapshot at its launch prices ($10 USD input, $12.50 USD 5-minute write, $20 USD 1-hour write, $0.25 USD cache read, $50 USD output per million tokens), three settings per schedule: the 5-minute cache, the 1-hour cache, and the 5-minute cache kept warm by a `max_tokens: 0` request on the unchanged prefix every 4 minutes, timed from the previous request’s start (the August 23 runs sent keep-alive requests with `max_tokens: 1`; in the August 26 cells reported here, every answered keep-alive request refreshed the cache and its response reported no output tokens).

These runs used Terminal-Bench version 3.0, and their scores are not comparable with the public Terminal-Bench leaderboard or with the Terminal-Bench 4.0 results in the Claude Opus 5.5 system card, which come from runs in Claude Code at `max` effort. Each task's time limits are 2.5 times the benchmark's own, which gives the agent between 75 minutes and 20 hours per task (5 hours for the median task), and each task gets three times the memory it specifies, from 6 GiB to 96 GiB, with extra memory for the 12 tasks that run helper services. The agent had no general internet access: its containers could reach an internal package mirror, a short list of download sites including GitHub and the Python Package Index, and a few sites specific to some tasks, and eight of the tasks had no network access at all. Scores are raw pass rates over the 148 attempts per model; single runs swing by 5 to 11 points. Costs are what a customer would be billed at list prices, re-priced request by request from the runs' usage records with the 5-minute cache lifetime. Claude Opus 4.7, Claude Opus 4.8, and Claude Opus 5 each spend $8 USD to $15 USD per task.

The team is a lead agent that can start helper agents of the same model through a tool, with no cap on their number. - * **The sentence:** The two changes are a sentence and a clock. The sentence, "Time matters here: do not spend time that can be avoided, and the earlier a correct result is obtained, the better.", goes at the end of the task in the agent's first `user` message, after a blank line, and at the end of each helper's brief. - * **The clock:** The clock is the elapsed time in whole seconds, such as `[elapsed 252s]`, added before every request, including the first, to the end of the newest `user` message: in its own text block after the task on the first request, and at the end of the last tool result's text, after a blank line, when the message carries tool results. Earlier clocks stay in place, so the cached prefix still matches on the next request. Every agent in a team reads the same clock, and the system prompt doesn't change. - * **In the measured runs:** The measured runs used this wording and format. Their clock started at the first token of the first response rather than at the start of the task. In the measured team runs, a helper's report reached the lead in a separate message after the clock, not inside the last tool result. + * **Configurations:** Every configuration ran on the Claude API with Claude Opus 5.5, the default adaptive thinking, the production safety classifiers on, and `max_tokens` at 128,000 with streaming: a single agent at `medium` effort (the model’s default) and at `low`, the single agent at `medium` with the sentence and the clock, and a team at `medium` with and without them.

In the measured team runs, a helper’s report reached the lead in a separate message after the clock, not inside the last tool result. * **When:** Each configuration made three attempts at each task, with a four-hour limit per attempt, run September 24, 2026, and all configurations of a set started together. * **Tools:** The agents used search and fetch tools that the evaluation harness hosts over an Anthropic web index, and Python and a shell in a sandbox with no network access. Those tools set part of the time, and yours will run at a different speed, so the page gives time as a ratio between configurations, not in minutes. - * **How timed:** Time is the wall-clock time of an attempt, from its first request to the end of the last request by any agent, including tool runs, averaged over a task's attempts. A typical-task figure is the median, over tasks, of each task's ratio between two configurations. - * **How priced:** Each task's cost is its requests priced at Claude Opus 5.5's public list prices, with prompt caching billed as it would be for a customer who sets a cache breakpoint at the end of each request and uses the 5-minute cache lifetime. Each request reads the previous request's prompt from the cache and writes the rest. An attempt's first request, and any request that starts more than 5 minutes after the one before it, writes its whole prompt. Costs cover model tokens only; the harness's tools add no charges. - * **How scored:** All intervals are 95% bootstrap intervals over tasks, and score changes are paired differences over tasks. Claude Opus 5 grades the answers, so Claude Opus 5.5 doesn't grade its own work, and each answer's score averages five judging runs. - * **Caveats:** A production safety classifier stopped three attempts in each configuration, all on one task, and those attempts score 0; leaving that task out changes no finding. The runs also passed each agent's tool use through an Anthropic-internal safety check that customer requests don't have, which adds time to each request in every configuration. On DRACO, the single agent without the changes made about twice as many requests, and the team about a third more, so the check probably makes the DRACO time savings look slightly larger. + * **How timed:** Time is the wall-clock time of an attempt, from its first request to the end of the last request by any agent, including tool runs, averaged over a task’s attempts.

At `low` effort, it scored 13.3 points lower on DRACO, 3.4 on HLE, and 14.0 on the physics set than at `medium`, and the typical task took 84%, 30%, and 47% less time. With the changes at `medium` effort, it scored 9.2, 2.5, and 11.0 points higher than at `low`, and the typical task took longer than at `low` by a factor of 1.2 to 3.2. - * **Results, team, helpers:** The team's lead rarely started helpers.

Expert reviewers corrected the problem statements. Claude Opus 4.6 grades each answer with partial credit, using the set's grading prompt, against expert reference solutions that aren't public, so the scores can't be compared with published results.

The caching before-and-after pair ran on September 8, 2026. - * **How scored:** In the searches, the starting points and the confirmed configuration are the mean of three held-out runs, kept steps were judged on two runs, and other candidates were scored on one or two runs. The caching pair: three runs each on all 114 tasks with only the harness's cache breakpoints toggled, the configuration the `cost-optimize` command produced in an earlier run. Held-out numbers are on 57 tasks the search never read. - * **How priced:** Cost per task prices the agent's and the simulated user's token counts at list prices (Claude Opus 5 $5 USD and $25 USD, Claude Sonnet 5 $2 USD and $10 USD per million input and output tokens, cache reads and writes at their published rates) and excludes the judge; percent changes come from unrounded costs; the monthly figure is the agent's tokens alone, $0.135 USD and $0.047 USD per task, times 10,000.

At 10,000 conversations a month, that is about $1,350 USD before the first search and $470 USD after. * **Caveats:** These measurements ran on the previous Claude Opus and Claude Sonnet models: the caching pair ran on Claude Sonnet 5, the second search started from Claude Sonnet 5, and the first search went from Claude Opus 5 to Claude Sonnet 5. * **Caching pair:** The pair ran on Claude Sonnet 5 at the default effort. The public harness, as shipped, sends the whole conversation uncached on every turn. The cached configuration has one breakpoint on the system prompt and one on the latest message. Both searches ran with that caching on. Cost per task went from $0.223 USD uncached to $0.062 USD cached, a 72% saving, and the pass rate from 79.2% to 76.0%. Identical cached runs of that configuration ranged from 85 to 93 of 114 across days. Every cached run scored at or below every uncached run, but the gap of under 4 tasks sits inside the spread of identical cached runs, so the accuracy change is too small to measure at this sample size. * **How the search ran.** The `hillclimb` command asks four questions, presents a plan, and waits for approval before it spends anything. In the first search, the plan left the user simulator, grader, caching, temperature, and tasks unchanged. The last of the four questions began: `One pass over the full set is 114 cases x 1 rep on claude-opus-5, roughly 22 minutes.` Each round, the search proposes one change and runs the full set. It keeps the change only when the number moved and the predicted mechanism shows in the usage data. It stops when three rounds in a row bring nothing, then confirms the winner on fresh runs. * **First search, result.** The search cut cost per task by 61% while holding the pass rate within a 2-point band set before the search: from Claude Opus 5 at the default effort ($0.142 USD a task, 76.0% passed) to Claude Sonnet 5 at `low` with one cost-neutral prompt edit ($0.055 USD, 74.3%). The search cost $179 USD in evaluation runs and $228 USD in its own tokens. * **First search, start: Claude Opus 5, default effort.** 76.0% at $0.142 USD. Three identical runs spanned 43 to 44 of 57.

Each task ran five times per model. * **Runs:** The figures are from one run per model on October 7, 2026, graded that day. In three more runs of the same tasks on October 8 and 9, 2026, Claude Haiku 5.5 passed 91% to 93% of attempts, and in one more run on October 8, Claude Haiku 4.5 passed 63%. - * **How scored:** An attempt passed only if the grader, Claude Sonnet 4.6, grading once, marked every line of the task's checklist as met, so pass rates depend on the grader. On all but one task, a separate call, shown the tool results in full, graded the line that checks the files and messages the agent wrote through its tools against those results. + * **How scored:** An attempt passed only if the grader, Claude Sonnet 4.6, grading once, marked every line of the task’s checklist as met, so pass rates depend on the grader. On all but one task, a separate call, shown the tool results in full, graded the line that checks the files and messages the agent wrote through its tools against those results. * **How priced:** Costs are token costs at list prices with 5-minute prompt caching, priced request by request, and exclude session runtime. - * **Results, token prices and cost:** Claude Haiku 4.5 did not cache 80% of its requests: each had a prompt of about 4,100 tokens or fewer, and its minimum cacheable prompt length is 4,096 tokens (512 for Claude Haiku 5.5). From Claude Haiku 4.5 to Claude Haiku 5.5, token prices fell by up to 90%, and the token cost of the 79 tasks fell by about 75%. The token cost fell less than the prices because about 5% of Claude Haiku 5.5's requests had prompts over 100,000 tokens, which pay higher prices ([Long context pricing](https://platform.claude.com/docs/en/about-claude/pricing#long-context-pricing)), and they carried 73% of its cost. - * **Thinking:** Anthropic set Claude Haiku 5.5's effort to `medium` and sent no thinking setting or output limit for either model, so thinking was left to Claude Managed Agents' own settings for each model. Claude Haiku 5.5 used thinking in 59% of requests, and Claude Haiku 4.5 in 22%. The comparison is of each model as served, not at equal settings. - * **Cost without caching, priced from recorded token counts:** Anthropic also re-priced the recorded token counts of Claude Haiku 5.5's October 7 run for the caching factor in [Why caching comes first](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#why-caching-comes-first). Claude Managed Agents applies prompt caching itself, so the factor compares two prices for the same requests, not two settings. - * **The factor:** The factor, 1.7, is the run's token cost with every input token at the input price, output tokens unchanged, divided by its token cost with each session priced by itself: each request's prior prompt as a cache read and its new tokens as a 5-minute cache write. Each request is priced for its own prompt length in both costs, so the 87 requests over 100,000 tokens pay the higher prices in both. On the token counts as recorded, which this guide's costs for the run use, the factor is 1.9, because the five attempts of a task ran side by side and read each other's cache entries. + * **Results, token prices and cost:** Claude Haiku 4.5 did not cache 80% of its requests: each had a prompt of about 4,100 tokens or fewer, and its minimum cacheable prompt length is 4,096 tokens (512 for Claude Haiku 5.5).

On the token counts as recorded, which this guide’s costs for the run use, the factor is 1.9, because the five attempts of a task ran side by side and read each other’s cache entries. * **Why the factor is low:** The factor is low because the sessions are short, a median of 4 requests: most input tokens arrive as tool results on the second or third request and are read from the cache only once or twice. Eight long-context tasks hold three quarters of the cost. A second run, on October 8, also gives 1.7. 26. **Answer-format measurement:** - * **What was measured:** The 20-issue triage job from [Trim input and context tokens](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#trim-input-and-context-tokens), run on Claude Sonnet 5 with prompt caching on and no thinking setting in the request, so thinking was left at the model's default, under three final-answer instructions, three runs per instruction. + * **What was measured:** The 20-issue triage job from [Trim input and context tokens](https://platform.claude.com/docs/en/about-claude/models/optimizing-for-cost-and-intelligence#trim-input-and-context-tokens), run on Claude Sonnet 5 with prompt caching on and no thinking setting in the request, so thinking was left at the model’s default, under three final-answer instructions, three runs per instruction. * **Two-line instruction:** The original asked for two lines: `4. Finish with exactly two lines: LABEL: SUMMARY: ` * **One-line instruction:** The shorter variant asked for one: `4. Finish with exactly one line in this form: DECISION | LABEL | REASON where DECISION is one of: triage-now, needs-info, close-duplicate; LABEL is one of: bug-confirmed, needs-more-info, duplicate-candidate, feature-request, upstream-issue, perf, ui-polish; REASON is one clause under 15 words. Output nothing after that line.` * **Memo instruction:** The longer variant asked for a memo with six headed sections: problem summary, evidence, duplicate check, recommended label, next steps, and confidence. - * **Also in the instructions as sent:** As sent, the two-line instruction also said "Be concise." and the memo instruction "Be thorough and explicit." + * **Also in the instructions as sent:** As sent, the two-line instruction also said “Be concise.” and the memo instruction “Be thorough and explicit.” * **When:** The two-line and one-line instructions ran on August 18, 2026, with `max_tokens` at 700, and the memo instruction on August 19, 2026, with `max_tokens` at 3,000. No response reached its cap. - * **How scored and priced:** Figures are the mean of the three runs at Claude Sonnet 5's list prices, and accuracy is exact match against the gold labels. - * **Results:** The one-line answer used 39% fewer output tokens than the two-line original and cost 13% less per run (from the unrounded means; the chart's rounded costs, $0.49 USD and $0.57 USD, give 14%).

The agent had its own two tools plus real tool definitions from public MCP servers, for a total of 7, 17, 52, 102, 252, or 502 tools, with every definition loaded or with the added ones marked `defer_loading` behind tool search. - * **How scored and priced:** Figures are the mean of the three runs at Claude Sonnet 5's list prices, and accuracy is exact match against the gold labels. - * **Results:** With every definition loaded, the run cost rose from $0.55 USD at 7 tools to $1.02 USD at 502 tools, nearly double.

The chart counts a change of under 10% as no change. * **Lever settings:** The lever settings differed between the two jobs: context editing cleared at least 2,000 tokens once the prompt passed 20,000 on the 20-issue job, and at least 40,000 once it passed 50,000 on the long one, keeping the three most recent tool uses, and compaction triggered at 50,000 input tokens on the 20-issue job and 80,000 on the long one. - * **How priced:** Each cost is the mean of the three runs, from the responses' usage fields at Claude Sonnet 5's list prices, with cache writes at $2.50 USD and cache reads at $0.20 USD per million tokens. + * **How priced:** Each cost is the mean of the three runs, from the responses’ usage fields at Claude Sonnet 5’s list prices, with cache writes at $2.50 USD and cache reads at $0.20 USD per million tokens. * **Results, input trimming:** A fifth setting, prompt caching with no input trimming, cost $0.57 USD a run on the 20-issue job and $1.38 USD on the long one, so input trimming took 26% off the first and 21% off the second. Against the same 20-issue job with caching off, which cost $3.36 USD a run (reference 16), prompt caching and input trimming together saved 88% (the unrounded means give 87.5%). * **Results, 20-issue run:** On the 20-issue run, where the job with no lever cost $0.42 USD a run, context editing cost 73% more, compaction ran once near the end of each run and cost 7% less, and the prune rewrote nothing, because no search result was over its 2,000-character threshold. * **Results, long run:** On the long run, where the job with no lever cost $1.09 USD a run, the prune cost 39% less, compaction 32% less, and context editing 4% more. diff --git a/content/en/about-claude/pricing.md b/content/en/about-claude/pricing.md index b41c16ccd4..012c817691 100644 --- a/content/en/about-claude/pricing.md +++ b/content/en/about-claude/pricing.md @@ -4,7 +4,7 @@ url: https://platform.claude.com/docs/en/about-claude/pricing description: Learn about Anthropic's pricing structure for models and features --- -This page provides detailed pricing information for Anthropic's models and features.

To reduce these risks, take precautions such as the following: 1. Run the browser and your executor in a dedicated container or virtual machine with minimal privileges, a fresh profile that holds no credentials, and no access to sensitive filesystems or internal networks; isolate any tool you run alongside it the same way. 2. Restrict the hosts the browser can reach to a domain allowlist enforced at the network layer and re-checked in your `navigate` handler after redirects, and block loopback, link-local, and private ranges unless the task needs them. - 3. Treat everything a page supplies as untrusted input. That includes the tab titles and URLs, and each download's `url`, `path`, and `error`, that you report in a [`browser_state`](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#track-tabs-and-page-state) block. Build page reads from what the page renders (the accessibility tree or visible text), not raw DOM source, so hidden text doesn't reach Claude. - 4. In your `navigate` handler, accept the history keywords `"back"`, `"forward"`, and `"reload"`, treat a URL without a scheme as `https://`, then parse the URL and refuse any scheme other than `http` or `https` (`javascript:`, `file:`, `data:`, `chrome:`, and so on) with an [error result](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#return-errors-from-your-executor).

When these classifiers identify a potential prompt injection, they will automatically steer the model to check whether the instruction really came from you before acting on it. -This extra protection isn't ideal for every use case (for example, use cases without a human in the loop), so if you'd like to opt out and turn it off, [contact support](https://support.claude.com/en/).

A [per-message effort](https://platform.claude.com/docs/en/build-with-claude/effort#change-effort-mid-conversation-beta) level they set isn’t carried over either: until a later message sets a level, turns run at the request’s top-level `output_config.effort`, or the model’s default if you don’t set one. To keep an instruction or effort level in force, state it again in a `role: "system"` message directly after the first new `user` turn that follows the kept turns. Tool changes inside those turns carry over on their own when the compaction request also carries `inline-tools-2026-09-15`: the returned block records their net effect in its `tool_changes` field, so send the block back unmodified.

You can also state the completion condition up front and have a separate, smaller model check the conversation against it at each end of turn, returning its reason as the next user message when the condition isn't met. Either way, stop after two or three automatic continuations on the same task rather than repeating them indefinitely, so that a run that is genuinely stuck ends and can be reviewed. +Treat a text-only end of turn as a report rather than as proof the task is done.

If your code builds the `messages` array itself, the Preserved thinking page covers: * [What counts as an edit](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#what-counts-as-an-edit), and [how to check whether your code makes an edit](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#how-to-tell-whether-your-integration-is-impacted). * The [API feature that replaces each common edit](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#replace-prefix-edits): mid-conversation system messages for new instructions and per-turn reminders, `tool_addition` and `tool_removal` blocks for tool changes, per-message `output_config` for effort changes, and server-side compaction and context editing for trimming. -* [Client-side compaction](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#custom-compaction-on-the-client): which patterns keep thinking valid and which don't. +* [Client-side compaction](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#custom-compaction-on-the-client): which patterns keep thinking valid and which don’t. * The [`thinking-binding-controls-2026-08-01` beta header](https://platform.claude.com/docs/en/build-with-claude/preserved-thinking#preserved-thinking-controls). It adds a `block_binding.prefix_mismatch_behavior` field (`"error"` or `"drop_block"`) to the thinking configuration and an `input_transformations` array to every response. The array lists each thinking block that the API dropped, or that failed the prefix check and was let through. ## Thinking and prompt caching [Prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching) interacts with thinking in a few specific ways. The following rules apply in both thinking modes. -**Configuration changes invalidate caching.** The thinking configuration and the resolved [`effort`](https://platform.claude.com/docs/en/build-with-claude/effort) level are rendered into the prompt itself, so changing any of them starts a new cache prefix. Switching between `adaptive`, `enabled`, and `disabled`, changing `budget_tokens`, and changing the effort value all invalidate cache breakpoints: message-level breakpoints always miss, and tool and system-prompt breakpoints can miss too, depending on where the model renders the configuration. Treat any thinking or top-level effort change as starting the cache over. On models that support [per-message effort](https://platform.claude.com/docs/en/build-with-claude/effort#change-effort-mid-conversation-beta), an effort change carried in a `role: "system"` message inside `messages` leaves the cached prefix intact. Consecutive requests that keep the same configuration preserve the cache, and setting a parameter explicitly to its default value is equivalent to omitting it. A thinking block the API drops under any [preserved-thinking condition](https://platform.claude.com/docs/en/build-with-claude/thinking#preserved-thinking) changes the cached prefix from that block's position onward. Blocks passed back unchanged keep the cache intact.

A worked demonstration with usage output is on the [Steering thinking](https://platform.claude.com/docs/en/build-with-claude/thinking-steering-and-cost#prompt-caching) page. **Thinking blocks are cached with tool results.** During a tool-use loop, caching occurs when you make a follow-up request that includes tool results. At that point the previous conversation history, including its thinking blocks, can be cached, and those cached thinking blocks count as input tokens in your usage metrics when read from the cache. This occurs automatically, even without explicit `cache_control` markers, and behaves the same for regular and interleaved thinking. The tradeoff: thinking blocks you never see again in responses still contribute to input token usage when read from cache. -**Whether prior blocks are in context at all is per-model.** The [preservation default](https://platform.claude.com/docs/en/build-with-claude/thinking#thinking-block-preservation-by-model) governs this.

Avoid cropping out key visual context solely to enlarge the text. * **Resizing:** Take into account that your image might be resized if it is too large (see [Resolution and token cost](https://platform.claude.com/docs/en/build-with-claude/vision#evaluate-image-size)); this might, for example, make text less legible. Consider pre-resizing your images, cropping them, or both. To have an oversized image rejected with an error instead of resized (important for [coordinate workflows](https://platform.claude.com/docs/en/build-with-claude/vision-coordinates)), mark the image block with [`"oversized_image": "error"`](https://platform.claude.com/docs/en/build-with-claude/vision-coordinates#oversized-image-error). * **Image compression:** Compressing images before sending them, using a lossy format such as JPEG or WebP (lossy mode), can reduce latency by reducing the size of requests. However, this can introduce artifacts that are detrimental to model performance, especially when multiple compression passes are applied. For example, heavy JPEG compression can make text difficult to read.

The second is when the event was recorded before your organization's log was created. For an organization enrolled before the transparency log was introduced, that includes its earlier history. Once your log exists and while you are enrolled, every event is appended to the log before the feed serves it. If a fault prevents the feed from obtaining the index, the feed delays the event rather than serving it without one. The event is not lost: it is already in the log and appears on the feed, index included, once the fault is remediated. An index-less event is not expected when it is dated after your log was created and falls inside a period when you were enrolled. +* **An event is served without `transparency_log_leaf_index` in only two cases.** The first is while your organization is not enrolled in Access Transparency, that is, before enrollment or between an un-enrollment and a re-enrollment.

Such IdPs include AWS IAM, Google Cloud, and any standards-compliant OIDC issuer (such as GitHub Actions, Kubernetes service accounts, SPIFFE, Microsoft Entra ID, or Okta). The workload exchanges its IdP-issued JWT at `POST /v1/oauth/token` for a short-lived Claude API access token, and the SDK refreshes that token automatically before it expires. There is no `sk-ant-api...` string to mint, distribute, or rotate. -Federation removes long-lived Claude API keys from your environment, which limits the damage that a leaked credential can cause and lets you manage access with the same IdP controls you already use for cloud resources. It does not, on its own, guarantee end-to-end security: the trust chain is only as strong as your identity provider's configuration, and a long-lived secret one step earlier in that chain (for example, a static cloud credential that can mint IdP tokens) can still undermine it. Pair federation with your provider's controls, such as IP allowlists, MFA, and audit logging. +Federation removes long-lived Claude API keys from your environment, which limits the damage that a leaked credential can cause and lets you manage access with the same IdP controls you already use for cloud resources.

Pair federation with your provider’s controls, such as IP allowlists, MFA, and audit logging. To configure federation, you create three resources in the Claude Console (a service account, a federation issuer, and a federation rule) and then point your SDK at the rule.

For Claude for Microsoft 365 and the Claude add-ins for Google Docs, Google Sheets, and Google Slides, deleting a conversation in the add-in occurs only on the client, so it is not reflected in the API: local sessions have no `deleted_at` field, and the session stays listed until retention removes it. -Local sessions carry an `updated_at` but no `status`: a local session has no server-side lifecycle status, and its visibility is governed by retention instead. A local session is captured as the series of Claude API calls (inference calls) that the client makes during the session, and retention applies to each captured call individually. `created_at` is the timestamp of the session's earliest retained call and `updated_at` the timestamp of its last, both UTC. As older calls age past the retention period, `created_at` advances accordingly, and once every call in a session has aged out, the session is no longer returned; `updated_at` tracks the most recent call and is unaffected until then. Because `created_at` can shift between runs, deduplicate on `id` when you re-walk the list over time. To keep transcripts current as sessions gain messages, poll with the `updated_at.gte` filter, overlapping consecutive windows. On the list endpoint `updated_at` is a lower bound: for a session still active at a page boundary or the upper end of a `created_at` window, it can momentarily lag the session's true last activity, and a new call only becomes queryable after the short processing delay noted earlier. Because of that lag, set each run's `updated_at.gte` a few minutes before your previous run's start time, not to the previous run's time exactly. A bound set to the exact previous time silently and permanently drops a session whose final call was still indexing at that moment, because once the bound advances past that call no later run returns it. Deduplicate the returned sessions on `id`, re-fetch their transcripts, and deduplicate messages on `id`. Retrieving a session, or its messages, always reflects the exact latest retained call, so a periodic reconciliation pass over an older window is a more thorough alternative to widening the overlap. +Local sessions carry an `updated_at` but no `status`: a local session has no server-side lifecycle status, and its visibility is governed by retention instead.

List cost is not your contracted price: if your organization has negotiated discounts, the session reaches its cap when the list-price total does, and your billed spend might be lower than the cap. Enforcement uses the exact, unrounded list cost. The `list_cost` (java, php: `listCost`; csharp, go: `ListCost`) figures reported on the session and its events are whole cents, rounded to the nearest cent, so a reported figure can read up to half a cent either side of the exact amount enforcement uses. ## When a session reaches its budget -The cap is enforced between model requests, not mid-request. Before each model request, the platform checks the session's consumed list cost, and once that total reaches the cap every thread pauses before its next request. The request that carried the total past the cap was admitted while the session was still under it and runs to completion. As a result, a paused session's recorded `list_cost` (java, php: `listCost`; csharp, go: `ListCost`) reads at or a fraction past `max_list_cost` (java, php: `maxListCost`; csharp, go: `MaxListCost`). For example, a session capped at `"50"` (50 cents) can pause with a `list_cost` (java, php: `listCost`; csharp, go: `ListCost`) of `"53"`. This is expected, not a billing error. Model spend past the cap is at most the cost of one model request for each thread.

No thinking blocks are carried over, so nothing fails.

For schema-valid JSON, keep `tool_choice: {"type": "auto"}` and set `strict: true` with [strict tool use](https://platform.claude.com/docs/en/agents-and-tools/tool-use/strict-tool-use), or move the schema to [structured outputs](https://platform.claude.com/docs/en/build-with-claude/structured-outputs).

Manual extended thinking (`budget_tokens`), the sampling parameters `temperature`, `top_p`, and `top_k`, and assistant message prefill can each return a 400 error. `computer_20250124` also returns a 400 error: use the `computer_toolset_20260801` toolset on the Claude API and Google Cloud, or `computer_20251124` on Amazon Bedrock. A request that sends thinking blocks back after a change to `system`, `tools`, or earlier turns can also return a 400 error. Adaptive thinking is on by default, so a response can begin with `thinking` blocks, and their text is omitted unless you set `thinking.display` to `"summarized"`. The same text also counts as more tokens. See the [migration guide](https://platform.claude.com/docs/en/models/haiku-5-5/migration-guide) for each change. For model-specific prompting patterns, see [Prompting Claude Haiku 5.5](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/prompting-claude-haiku-5-5). * The Python and TypeScript SDKs now include classes, in beta, for the [browser use tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool) and the [computer use tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool). You subclass one and write one method per tool against your own browser or desktop automation. The SDK runs the tool loop, the URL and file policies you set for the browser, and your approval callback.

A `web_fetch` call for a URL on a host that `allowed_hosts` does not match returns a `url_not_allowed` error result to the agent. `web_search` omits results from such hosts. When `allowed_hosts` lists no hosts, neither tool returns a page or a search result. `allow_package_managers` and `allow_mcp_servers` add no hosts for these tools. To let the tools reach a host, add it to `allowed_hosts`, which also opens it to the sandbox. `unrestricted` networking and self-hosted environments do not limit these tools. See [Environment networking](https://platform.claude.com/docs/en/managed-agents/environments#networking). -* With `limited` networking, creating a session fails with a 400 error when an enabled web tool's `allowed_domains` has an entry not within `allowed_hosts`. So does a session update that adds such an entry. An `allowed_hosts` entry matches one exact host unless it starts with `*.`, so `docs.example.com` is not within `["example.com"]`. To fix the error, add the host to `allowed_hosts` or remove the entry from `allowed_domains`.

This reduces the risk of data exfiltration. A URL that appears only in Claude's own output, the agent's system prompt, an attached document, or the output of a tool such as `bash`, `read`, or an MCP tool does not count: a `web_fetch` call for it returns a `url_not_in_prior_context` error result to the agent.

Usage and cost reports and the Claude Enterprise user-management and analytics endpoints remain curl-only. The CLI and SDKs read an Admin API key from `ANTHROPIC_API_KEY` or an `org:admin` OAuth token from `ANTHROPIC_AUTH_TOKEN`. ### August 20, 2026 -* We've released **v1.0 of the [Python SDK](https://platform.claude.com/docs/en/cli-sdks-libraries/sdks/python)**. The SDK's HTTP layer moves from `httpx` to [httpx2](https://httpx2.pydantic.dev), a maintained, API-compatible fork: build custom `http_client`, `Timeout`, and transport objects from `httpx2` (the `DefaultHttpxClient` helpers are unchanged), and call `httpx2.alias_httpx()` at startup if you rely on tracing or mocking libraries that patch `httpx`. v1.0 requires Python 3.10 or later and removes long-deprecated surface, including the legacy Text Completions API, the `temperature`, `top_p`, and `top_k` parameters on Messages methods, and the tool runner's client-side `compaction_control`. On the async client, `.with_raw_response` results now need `await response.parse()`, and `AnthropicBedrock` now raises an error when no AWS region is configured instead of defaulting to `us-east-1`.

The agents should do the following, then return a list of issues and the reason each issue was flagged (eg. CLAUDE.md adherence, bug, historical git context, etc.): - a. Agent #1: Audit the changes to make sure they compily with the CLAUDE.md. Note that CLAUDE.md is guidance for Claude as it writes code, so not all instructions will be applicable during code review. - b. Agent #2: Read the file changes in the pull request, then do a shallow scan for obvious bugs. Avoid reading extra context beyond the changes, focusing just on the changes themselves. Focus on large bugs, and avoid small issues and nitpicks. Ignore likely false positives. - c. Agent #3: Read the git blame and history of the code modified, to identify any bugs in light of that historical context - d. Agent #4: Read previous pull requests that touched these files, and check for any comments on those pull requests that may also apply to the current pull request. - e. Agent #5: Read code comments in the modified files, and make sure the changes in the pull request comply with any guidance in the comments. -5. For each issue found in #4, launch a parallel Haiku agent that takes the PR, issue description, and list of CLAUDE.md files (from step 2), and returns a score to indicate the agent's level of confidence for whether the issue is real or false positive. To do that, the agent should score each issue on a scale from 0-100, indicating its level of confidence. For issues that were flagged due to CLAUDE.md instructions, the agent should double check that the CLAUDE.md actually calls out that issue specifically. The scale is (give this rubric to the agent verbatim): - a. 0: Not confident at all. This is a false positive that doesn't stand up to light scrutiny, or is a pre-existing issue. - b. 25: Somewhat confident. This might be a real issue, but may also be a false positive. The agent wasn't able to verify that it's a real issue. If the issue is stylistic, it is one that was not explicitly called out in the relevant CLAUDE.md. - c. 50: Moderately confident. The agent was able to verify this is a real issue, but it might be a nitpick or not happen very often in practice. Relative to the rest of the PR, it's not very important. - d. 75: Highly confident. The agent double checked the issue, and verified that it is very likely it is a real issue that will be hit in practice. The existing approach in the PR is insufficient. The issue is very important and will directly impact the code's functionality, or it is an issue that is directly mentioned in the relevant CLAUDE.md. - e. 100: Absolutely certain. The agent double checked the issue, and confirmed that it is definitely a real issue, that will happen frequently in practice. The evidence directly confirms this. -6.

For example, if an issue such as "variable is not defined" was flagged, the subagent's job would be to validate that is actually true in the code. Another example would be CLAUDE.md issues. The agent should validate that the CLAUDE.md rule that was violated is scoped for this file and is actually violated.

Specification releases occur every six months, generally on the last Tuesday of March and September. Each release has an eight-month cycle: two months of planning, a defined Core Maintainer review window, and stabilization before publication. Successive cycles overlap by two months. + +A Working Group or the Core Maintainer group sponsors each SEP. Proposal development continues year-round, and all SEP types use the scheduled Core Maintainer review window. Release-bound proposals must be Final and merged by soft freeze. SDK implementation begins after acceptance. Unfinished proposals move to a later cycle without moving the release date. + +A primary and secondary release manager coordinate each cycle, with the secondary becoming primary for the following release. The proposed transition moves the December 2026 release target to late March 2027, followed by the recurring cadence. + +## Motivation + +Contributors need to know when priorities are set, when proposals can receive a decision, and when implementations must be ready. Core Maintainers have limited review capacity, while Working Groups and SDK maintainers need enough time to develop proposals, test implementations, and resolve ambiguities before a specification is released. + +The current [SEP guidelines](https://modelcontextprotocol.io/community/sep-guidelines.md) define sponsorship, review, acceptance, and finalization, but do not connect those stages to a recurring release calendar. The [SDK tiering policy](https://modelcontextprotocol.io/community/sdk-tiers.md) expects Tier 1 support before a specification release, with timelines agreed per release. Explicit milestones make that coordination predictable. + +The Core Maintainers established this proposed process during the latest Core Maintainer Day at MCPCon Europe. This SEP formalizes that proposal. Unfinished proposals move to the next release. + +## Specification + +### Release Cadence Overview + +MCP generally publishes specification releases on the last Tuesday of March and September. Release managers confirm the exact date in each cycle's published calendar. Each cycle begins eight calendar months before its target release date. The first two months are dedicated to planning, and the final two months overlap planning for the following release. + +All release milestones are expressed in calendar months before release, including half-month intervals. These offsets set the planning targets; the published release calendar defines the exact dates and deadlines. + +| Milestone | Timing before release | Outcome | +| - | - | - | +| Planning begins | 8 months | Propose a roadmap and gather maintainer and WG feedback. | +| CM review opens | 6 months | Publish priorities and begin scheduled SEP reviews. | +| Soft freeze | 2.5 months | Close review and freeze scope to Final, merged SEPs. | +| Next-cycle planning | 2 months | Begin planning the following release. | +| SDK beta | 1.5 months | Publish Tier 1 SDK betas for ecosystem testing. | +| Hard freeze | 1 month | Restrict specification changes to emergencies. | +| Release | 0 months | Publish the specification, release notes, and readiness guidance. | + +The two cycles below share one month axis. **Late January through late March is the two-month overlap:** the March release is stabilizing while planning for the September release is underway.

For a September release, the same overlap runs from late July through late September while the following March cycle begins planning. SDK beta and freeze timings are listed in the milestone table above. + +### Release Management + +Each release has a primary and secondary release manager. Release managers are Maintainers who self-nominate and are selected by affirmative votes from more than half of all eligible Core Maintainers (CMs). Voter eligibility follows [Voting and Recorded Outcomes](#voting-and-recorded-outcomes). + +Core Maintainers give both release managers the access needed for their duties, including repositories, release tooling, the review queue, and communication channels, and invite them to all CM meetings. + +A manager serves as secondary for one cycle and primary for the next. CMs select an incoming secondary before planning for the following release begins. + +The primary is accountable for the release calendar, review scheduling, scope tracking, freeze coordination, SDK readiness, publication, and communication. The secondary participates in that work, maintains the queue and handoff notes with the primary, and learns the release procedures. Release managers coordinate and escalate decisions; SEP acceptance and exception authority remain with the roles specified in this SEP. + +If a manager becomes unavailable, CMs select a replacement through the same nomination and voting process and record the revised assignments. + +After the first release under this process, release managers publish a retrospective covering queue wait times, readiness at soft freeze, SDK beta availability, emergency changes, and manager workload during overlap. Substantive changes to this process follow the SEP workflow. + +### Planning — 8 Months Before Release + +Planning begins 8 months before release and runs until the CM review window opens at 6 months before release. At the start of planning, release managers publish exact milestone dates and cutoff times for the cycle. + +During planning, Core Maintainers propose a roadmap, gather feedback from maintainers and Working Groups (WGs), and publish priorities covering a six-to-twelve-month horizon. Planning identifies dependencies across WGs and SDKs. Roadmap inclusion establishes review priority without guaranteeing acceptance or inclusion in a particular release. + +### CM SEP Review — 6 to 2.5 Months Before Release + +The CM review window opens six months before release and closes at soft freeze. It applies to Standards Track, Extensions Track, Process, and Informational SEPs. Scheduled pre-reviews and formal reviews take place within this window. Queue submissions can be made throughout the year. + +WGs continue drafting, prototyping, gathering community feedback, and conducting internal reviews throughout the cycle. Specification changes for later releases remain in proposal branches or PRs until the current release is published. + +Process and Informational SEPs can take effect after acceptance and completion of their implementation requirements. Extensions retain their own publication lifecycle. Their CM review timing follows this SEP, while specification freezes apply to the scope of the specification release being prepared. + +#### Sponsorship and Submission + +SEPs require sponsorship from a Working Group or the Core Maintainer group before formal review. A named representative acts on the sponsoring group's behalf. Sponsorship supports bringing the proposal to review; formal acceptance requires a separate decision. + +* **WG sponsorship:** Develop the proposal in a publicly readable WG-designated repository or fork and obtain approval through the existing [WG decision-making process](https://modelcontextprotocol.io/community/working-interest-groups.md#decision-making-process). The WG lead records the decision and unresolved concerns, then submits the ready SEP to the [SEP review queue](https://voting.modelcontextprotocol.io/p/seps). +* **Core Maintainer group sponsorship:** The Core Maintainers agree to sponsor the proposal and designate a CM to represent the group. That representative records the sponsorship decision, consults relevant WGs, and submits the ready SEP to the same queue. No separate WG approval is required. + +Before queue submission for formal review, both paths require a canonical SEP PR in the main MCP repository. Use a placeholder number until that PR supplies the SEP number, following [SEP-1850](https://modelcontextprotocol.io/seps/1850-pr-based-sep-workflow.md). WG-sponsored PRs link to the WG review and approval; proposals sponsored by the Core Maintainer group may start directly in the main repository. Record the sponsoring group's decision and consultation with affected WGs in the PR. + +The SEP's Sponsor field names the Maintainer or Core Maintainer acting on the sponsoring group's behalf and responsible for status, labels, and implementation tracking. A qualified WG lead may fill this role; for Core Maintainer group sponsorship, the designated CM does so. + +Both paths follow the same queue, review schedule, and acceptance requirements. When a SEP is selected for discussion, the release manager invites the WG lead or designated CM, as applicable, and all SEP authors to the CM meeting. + +#### Review Queue and Scheduling + +Release managers maintain the public [SEP review queue](https://voting.modelcontextprotocol.io/p/seps). Each entry records a link to the proposal, sponsoring group and representative, named maintainer sponsor when assigned, requested review type, readiness date, roadmap alignment, and target review cycle. Formal review entries link to the canonical upstream SEP PR. Pre-review entries may link to an initial proposal without an upstream SEP number or completed group approval. + +A WG lead or designated CM may request optional pre-review to discuss direction, dependencies, and major concerns before investing in a complete proposal. Pre-review provides guidance and does not grant acceptance or reserve release scope. + +For each agenda, release managers prioritize ready formal reviews, then pre-reviews. Within each category, roadmap-aligned proposals come first, followed by readiness date, oldest first. Record the reason for any scheduling exception in the queue. A proposal returned for substantive revision receives a new readiness date when resubmitted; a ready proposal deferred solely for lack of agenda time retains its readiness date. + +Formal reviews take place at regular Core Maintainer meetings during the review window. For each formal review: + +1. **Two weeks before the meeting:** Release managers select ready proposals with Core Maintainers and publish the agenda and proposal links. +2. **During the preceding week:** Reviewers leave asynchronous comments. Authors and sponsors respond and identify questions requiring discussion. +3. **At the meeting:** The author, WG lead, or designated CM presents the proposal, remaining questions, and available implementation feedback. +4. **After the presentation:** Open the recorded vote described below, then publish the outcome and required follow-up on the SEP PR and in the queue. + +Scheduled votes must conclude and pass before the applicable soft or hard freeze. Release-bound SEPs must be Final and merged before soft freeze; subsequent corrections must be merged before hard freeze. All applicable requirements, including conformance tests, must be met before merging. Changes after hard freeze require emergency approval. Queue placement guarantees neither review time nor release inclusion. + +#### Voting and Recorded Outcomes + +After presentation, the named maintainer sponsor opens a recorded seven-calendar-day vote in the maintainer Discord server and links the voting record from the SEP PR. The record identifies the proposal revision being voted on, the closing time, and eligible voters: the current Core Maintainer group, including Lead Maintainers and excluding emeritus members, as recorded when voting opens. + +Acceptance requires affirmative votes from more than half of all eligible voters. Abstentions and absences do not count as approval, and a majority of those attending a meeting alone is insufficient. A majority voting to reject produces a rejection; otherwise a proposal that does not reach the acceptance threshold returns for revision or later review. The sponsor records the tally, decision, rationale, and follow-up on the SEP PR and updates its status under the existing guidelines. + +The voting period remains open for all seven days, except for shortened emergency votes under [Hard Freeze](#hard-freeze--1-month-before-release). A material change to the proposal during that period returns it for review rather than being accepted under votes cast on the earlier revision. A vote that cannot conclude before the review window closes is deferred to the next window without a partial result counting as acceptance. + +The rules in effect when a vote concludes apply, even if voting began before a freeze. After soft freeze, only corrections within the frozen scope can proceed; after hard freeze, changes must meet the emergency criteria and full CM voting requirements. Approval does not exempt a change from the freeze rules in effect when it is merged. + +Existing [Lead Maintainer authority](https://modelcontextprotocol.io/community/governance.md#roles) remains in effect. Where a proposal amends governance, the stricter proposal, comment-period, and approval requirements of [SEP-2085](https://modelcontextprotocol.io/seps/2085-governance-succession-and-amendment.md) apply. + +#### Implementation After Acceptance + +SDK maintainers should begin implementation as soon as a SEP is accepted. Early implementations and prereleases should feed ambiguities and interoperability findings back to the author, sponsor, relevant WGs, and Core Maintainers while changes can still be made. + +SDK implementations are not required for a SEP to reach Final. + +### Soft Freeze — 2.5 Months Before Release + +At soft freeze, every SEP included in the specification release must be Final and its changes merged. This includes the specification text, applicable schema changes, changelog entry, completed reference implementation, and any conformance tests required by [SEP-2484](https://modelcontextprotocol.io/seps/2484-conformance-tests-required-for-final-seps.md). Acceptance alone does not meet the cutoff. + +Release managers publish the frozen scope and deferred proposals. From soft freeze until hard freeze, changes are limited to bug fixes, polish, and clarifications within that scope. New features and substantial redesign move to a later cycle. Corrective changes follow normal review and applicable testing requirements. + +An accepted proposal that misses finalization remains Accepted and is tracked for a later release. A proposal still awaiting a decision retains its existing status and returns to the queue. Deferral alone does not require repeating an acceptance vote, but a material redesign requires renewed review. Rejected proposals follow the existing rejection and resubmission process. + +Release inclusion in a later cycle still depends on readiness and that cycle's scope. The release date does not move to accommodate unfinished proposals. + +### Next-Cycle Planning — 2 Months Before Release + +Planning for the following release begins 2 months before the current release, while the current release remains in stabilization. This is 8 months before the following release. The next cycle follows the planning process above, ending planning and opening its CM review window on the current release day. + +During this two-month overlap, the current secondary release manager also serves as primary for the following cycle. They support current-release stabilization while leading next-cycle planning with the incoming secondary. The outgoing primary remains accountable for the current release through publication. + +### SDK Beta — 1.5 Months Before Release + +Tier 1 SDKs publish beta versions supporting the frozen specification scope 1.5 months before release, giving client and server developers half a month to report issues before hard freeze. Beta release notes identify the target specification release, available functionality, known gaps, and where to report feedback. SDK maintainers provide conformance results and outstanding blockers to the release managers. + +This milestone covers features required by the SDK tiering policy; it does not make experimental features or extensions mandatory for Tier 1. Other SDKs are encouraged to join the beta milestone and continue to follow their existing tier commitments. + +Release managers maintain a public readiness summary with SDK versions, conformance results, gaps, owners, and expected resolution dates. Missed beta or stable milestones are escalated to Core Maintainers and the SDK WG and disclosed in release guidance. An individual SDK delay does not postpone specification publication or automatically change that SDK's tier; tier decisions remain under the existing tiering policy. + +### Hard Freeze — 1 Month Before Release + +Hard freeze begins 1 month before release. Every change to the frozen specification requires approval through a full Core Maintainer vote. Only changes addressing critical security vulnerabilities or release-blocking correctness or interoperability defects are eligible for a vote. Feature additions and discretionary redesign do not qualify. + +The primary release manager coordinates each exception through the normal PR workflow: + +1. Confirm that the proposed change meets the emergency criteria above. Document the qualifying defect, why it cannot wait, the smallest proposed correction, and its effect on SDKs and release artifacts. Changes that do not meet the criteria must not be submitted for a vote. +2. The primary release manager opens a recorded vote for the corrective PR to the full Core Maintainer group. A separate SEP, SEP sponsor, or meeting presentation is not required. +3. Obtain review from affected implementation maintainers and run relevant regression and conformance checks before merging. Where observable protocol behavior changes, update applicable conformance coverage. +4. Record the vote, decision, validation results, and any changed implementation guidance. Notify affected SDK maintainers and update the readiness summary and release notes. + +Emergency votes may take place and conclude outside the CM review window. The primary release manager may shorten the seven-day voting period when needed, notifying all eligible CMs of the deadline and reason. Approval still requires affirmative votes from more than half of all eligible CMs. Voter eligibility and Lead Maintainer authority follow [Voting and Recorded Outcomes](#voting-and-recorded-outcomes). + +Approval and validation must be complete before merging. If a defect cannot be corrected safely in time, removing the affected new feature and its dependent changes also requires a qualifying emergency and approval through the same full CM vote. The remaining specification proceeds on schedule. + +Security-sensitive details follow the existing [security reporting and disclosure process](https://modelcontextprotocol.io/community/security.md). Keep the decision and validation record in the restricted channel during an embargo and publish it when disclosure permits. + +### Release — 0 Months Before Release + +Tier 1 SDKs publish stable support before specification publication, consistent with their existing feature-support commitments. + +On release day, publish the dated specification, release notes, implementation and migration guidance, and SDK readiness summary using the existing release procedures. Protocol versions retain their date-based format. Complete the handoff notes with outstanding issues and follow-up owners. The incoming primary continues leading the next cycle, whose review window now opens. + +### Transition and Adoption + +This SEP proposes moving the release previously targeted for December 2026 to March 30, 2027, the last Tuesday of March, subject to confirmation in the transition calendar. The last specification release was July 28, 2026. The first cycle uses the planning completed in August 2026. + +Within two weeks of adoption, Core Maintainers select the initial primary and secondary through the nomination and voting process above, and those managers publish the transition calendar, review meetings, and exact freeze, beta, and release deadlines. The first primary need not have served a preceding secondary cycle. The transition calendar opens the first review window when the process becomes operational and closes it at the March release's calculated soft freeze. Only meetings that allow the full agenda lead time and voting period are scheduled. + +Planning for September 2027 begins in late January 2027. Planning for March 2028 begins in late July 2027. Subsequent cycles follow the full recurring calendar. + +Existing upstream SEP PRs remain valid and retain their numbers, discussions, and completed decisions. Before their next formal review, proposals obtain sponsorship from a WG or the Core Maintainer group and enter the queue; authors do not need to close and recreate their PRs in a WG repository. Already accepted proposals retain acceptance and must meet release-readiness requirements. This SEP itself is considered under the process in force before its adoption. + +## Rationale + +### Predictable Dates with Flexible Scope + +A six-month release cadence gives implementers a regular planning horizon. Eight-month cycles allow roadmap planning to overlap stabilization, so one release can finish while priorities for the next are prepared. Expressing every release milestone in months makes the timeline easier to compare, while the published calendar provides exact deadlines. + +Delaying releases for unfinished proposals would make the next release harder to plan. Deferring scope instead gives unfinished work another opportunity without treating a missed deadline as rejection. + +### Review Capacity and Sponsorship + +WG review brings domain feedback and prototypes into proposals before they consume CM agenda time. A public queue makes priorities and deferrals visible. Applying the same CM window to every SEP type simplifies scheduling, although it can delay process and extension proposals that are ready outside the window. Continuous WG development and optional pre-review help contributors prepare for the next opportunity. + +Sponsorship by the Core Maintainer group provides a direct path for process changes, proposals spanning multiple groups, and topics without an established WG. Consultation with relevant WGs preserves domain feedback, and the same review and acceptance requirements apply to both paths. The named sponsor preserves accountability for status and implementation duties. + +### Readiness Before Stabilization + +Requiring Final, merged SEPs at soft freeze gives SDK maintainers a concrete specification to implement and test. Allowing merely accepted designs to enter stabilization would leave specification text or conformance work competing with bug fixes. Early SDK implementation reduces that risk without making every SDK implementation a condition of SEP finalization. + +### Recorded Votes and Emergency Review + +A seven-day vote allows participation across time zones and gives absent meeting attendees a defined opportunity to vote. Requiring a majority of the eligible group avoids acceptance based on a small meeting turnout, at the cost of needing enough participation before each deadline. + +Full Core Maintainer votes keep changes to frozen release scope accountable to the group. + +### Rotation and Transition + +Serving as secondary prepares a release manager to lead the next cycle. Naming responsibility for each overlapping cycle avoids an ambiguous handoff. Moving the upcoming target to late March 2027 creates time to introduce the calendar and readiness milestones while crediting planning already performed. + +## Backward Compatibility + +This SEP changes contribution and release processes. It introduces no protocol messages, schema changes, version-negotiation changes, or new requirements for deployed clients and servers. Existing date-based specification versions remain valid. + +WG-sponsored proposals gain a group approval stage, while proposals sponsored by the Core Maintainer group may proceed directly to upstream submission. Both paths use a seasonal CM review window. Existing proposal history and acceptance decisions are preserved as described in the transition procedure. This SEP updates the sponsorship and scheduling portions of SEP-1850 while retaining canonical upstream PRs, PR-based numbering, sponsor-managed statuses, and existing finalization requirements. + +SDK beta and stable milestones make release expectations explicit while preserving tier assignment procedures and the existing exclusion of experimental features and extensions from mandatory tier coverage. Final SEPs remain historical records; process adoption updates the current contributor guidance rather than rewriting those records. + +## Security Implications + +No new protocol attack surface, authentication behavior, or handling of user data is introduced. A fixed calendar must still allow critical security corrections during freezes. The emergency process requires a full Core Maintainer vote, implementation review, and relevant validation while preserving coordinated disclosure. Public queue entries and release notes must not disclose embargoed vulnerability details prematurely. + +## Reference Implementation + +For this Process SEP, implementation consists of contributor documentation and operational setup. The work required before Final status is: + +1. Update the current SEP guidelines and WG guidance to explain sponsorship, upstream submission, review scheduling, voting, and transition handling. +2. Publish release-cycle documentation and the first calendar, including exact UTC deadlines and review meetings. +3. Set up the public [SEP review queue](https://voting.modelcontextprotocol.io/p/seps), publish the SDK readiness summary, assign their maintainers, and record the initial release-manager appointments. +4. Publish a release checklist covering freeze scope, emergency approvals, SDK milestones, publication, and handoff. + +Link the documentation changes, calendar, queue, and assignments here as they become available. Process SEPs are exempt from protocol conformance-test requirements; existing release tooling can continue to perform publication. diff --git a/content/support/10310342-how-do-i-log-out-of-all-active-sessions.md b/content/support/10310342-how-do-i-log-out-of-all-active-sessions.md index 752b1b2d5f..5973c4c1d6 100644 --- a/content/support/10310342-how-do-i-log-out-of-all-active-sessions.md +++ b/content/support/10310342-how-do-i-log-out-of-all-active-sessions.md @@ -46,7 +46,7 @@ Logging out of all active sessions also logs you out of Claude Code.
