`OpenAiCompatibleLanguageModel::stream_completion` (used for custom
OpenAI-compatible providers) forwarded `request.speed` straight into
`into_open_ai`/`into_open_ai_response`, which translate `Speed::Fast`
into OpenAI's `service_tier` field. Custom OpenAI-compatible endpoints
don't recognize that field and reject the request.
`speed` can end up set even for a provider that doesn't support fast
mode: `Thread::inherit_parent_settings` copies `speed` from a parent
thread to a subagent without checking whether the subagent's model
supports it.
Every other provider sharing this conversion code already guards against
this (`open_ai.rs`, `anthropic.rs`, `anthropic_compatible.rs`,
`language_models_cloud.rs`). This adds the same guard for
`OpenAiCompatibleLanguageModel`.
Release Notes:
- Fixed requests to OpenAI-compatible providers (e.g. Baseten) sometimes
including an unsupported `service_tier` parameter
Manage various LLM settings (previously in agent panel) in settings UI.

When a Zed Business organization hits its token spend limit, the agent
panel told the user to "check that your API key has access to this
model", and did not display the error message returned by the server.
The message about checking your API key was the generic 401 and 403
error for all language model providers. This is also incorrect in
general since there are no API keys involved in the Zed and ChatGPT
Subscription providers.
So this commit changes the message for authentication errors (401s) to
be provider-specific, with the current message about invalid API key as
the default, and overrides for the providers that don't use API keys.
And the authorization error messages (403s) now include the server error
message. So the spend-limit case now reads "Permission Denied —
Token-based spending limit reached." instead of talking about API keys.

/>
Telemetry event names (`invalid_api_key`, `no_api_key`) are kept
unchanged to avoid breaking existing dashboards.
Release Notes:
- Fixed agent panel errors telling users to check their API key when the
provider doesn't use one (Zed account, ChatGPT subscription). Permission
errors also now show the provider's actual message.
Claude Fable 5 always thinks and cannot honor a request with thinking
disabled, but the cloud models listing gives clients no way to tell it
apart from models where thinking is optional (e.g. Claude Opus 4.6):
both report `supports_thinking: true` plus the same adaptive effort
levels. As a result, the agent panel shows a thinking toggle for Fable
even though turning it off isn't actually supported.
zed-industries/cloud#2789 adds a `supports_disabling_thinking` field to
the models listing. This PR mirrors it through
`cloud_llm_client::LanguageModel` (serde-defaulted to `false`, so a
server without the field is treated as "don't claim thinking can be
turned off") and exposes it as
`LanguageModel::supports_disabling_thinking()`, forwarded from the
listing by `CloudLanguageModel`. The agent panel now hides the thinking
toggle for models that report `false`, showing only the effort selector.
The trait default is `true`: every non-cloud provider in the tree treats
thinking as toggleable today, and only the cloud listing knows about
always-thinking models.
Draft until zed-industries/cloud#2789 lands and deploys.
Release Notes:
- Fixed the agent panel offering a thinking toggle for models that
cannot run with thinking disabled.

Adds support for Anthropic's Claude Fable 5 model when using your own
Anthropic API key. Because Fable 5 cannot be offered under Zero Data
Retention (Anthropic retains inference logs for 30 days), this gates the
model behind an explicit data-retention consent: a new
telemetry.anthropic_retention setting (default off, surfaced in the
Privacy section of the settings UI), and a hard, non-retryable check in
the cloud completion path that raises a typed error when consent is
missing.
When Fable 5 declines a request, it transparently falls back to Claude
Opus 4.8 (matching Anthropic's server-side behavior), and the agent
panel shows a callout for the consent error with "Switch to Opus 4.8" /
"Accept" actions that resume the failed turn so the user's message
continues without retyping.
Closes AI-382
Release Notes:
- Add Claude Fable 5 to Anthropic BYOK

## Summary
Adding an OpenRouter API key did not populate the model list until the
app was
restarted. `set_api_key` stored the credential but never triggered a
model
fetch, so until re-authentication happened (on restart or a settings
change)
the picker showed only the user-configured `settings.available_models`,
not the
models returned by the OpenRouter API.
This makes `set_api_key` refresh the models right after the key is
stored,
mirroring how `authenticate` already does it.
## Changes
- `set_api_key` awaits the credential store and then calls
`restart_fetch_models_task`, so the API model list loads immediately
after a
key is entered (and is cleared when the key is removed).
- `fetch_models` now maps `list_models` errors via
`LanguageModelCompletionError::from`, preserving the real OpenRouter
error
message instead of wrapping it in a generic `Other(...)`.
Release Notes:
- Fixed OpenRouter models not appearing until restart after adding an
API key

Adds Claude Opus 4.8 for BYOK providers, including Anthropic fast-mode
handling and Bedrock/OpenCode model definitions.
Closes AI-336
Release Notes:
- Added Claude Opus 4.8 BYOK support
## Summary
This started from #57636, after we saw ChatGPT subscription/Codex
requests stall over the past week. OpenCode v1.15.11 shipped related
resilience fixes for the same class of Codex subscription endpoint
issues, so this ports the relevant pieces into Zed's native ChatGPT
subscription provider.
When Zed asks ChatGPT/Codex for a response, sometimes the server
connection can get stuck before it even sends the first response
headers. Before this PR, Zed could wait indefinitely, which looks like
OpenCode/Zed “stalling.”
This PR makes Zed:
- Wait up to 10 seconds for the server to start responding.
- If nothing comes back in that window, treat it as a temporary
network/API failure.
- Let the existing retry logic try again instead of leaving the user
stuck.
- Send a stable session-id header so OpenAI’s Codex backend can
associate requests with the same Zed agent thread.
- Add tests to make sure:
- stuck-before-response requests time out,
- normal slow streaming responses are not cut off,
- ChatGPT subscription requests send the right session header,
- the agent retries this kind of failure.
intended user-facing result is: fewer “the assistant is just sitting
there forever” failures when using ChatGPT subscription models.
## Verification
- cargo test -p open_ai responses
- cargo test -p language_models openai_subscribed
- cargo test -p agent test_send_retry_on_http_send_error
- cargo check -p open_ai
- cargo check -p language_models
- cargo check -p agent
Release Notes:
- Fixed ChatGPT subscription requests stalling indefinitely before
response headers arrive.
Until now, the cloud-hosted model list was only refreshed in response to
events that exercise the LLM token (a `UserUpdated` push, an
organization change, or `PrivateUserInfoUpdated`). If a user wasn't
actively using AI features around the time we shipped new models, the
list could stay stale until they restarted Zed.
This is the second step toward fixing that, after #57078 made the cloud
websocket reconnect on its own. We now treat each successful (re)connect
as a hint that the server state may have changed, so possibly new model
definitions will be available, and trigger a model list refresh.
The trigger is a new `Client::cloud_connection_id()` watch that bumps a
counter each time the websocket handshake completes.
`CloudLanguageModelProvider::State` subscribes to it and, on every tick
after the initial `0`, schedules a debounced refresh (with jitter, so we
don't have all active clients trying to reconnect at the same time after
we deploy in cloud).
Closes CLO-713.
Release Notes:
- The list of Zed hosted models is now refreshed automatically, without
requiring a restart
It look like this:
<img width="1698" height="688" alt="grafik"
src="https://github.com/user-attachments/assets/02a37271-63d3-42da-887f-e17b31e8d9ca"
/>
The idea is to avoid people turning on fast mode without understanding
the financial implications. It also clarifiers (in the BYOK case) why
they might not see a difference between fast mode enabled and disabled.

Same mechanism as for BYOK: `service_tier == priority`. Most of the work
is already done. When validating this in manual testing, I noticed we
get back `service_tier == auto` in the response, unlike in the regular
OpenAI API scenario with BYOK, but apparently [it doesn't mean priority
tier wasn't
applied](https://github.com/openai/codex/issues/14204#issuecomment-4033184620).
It's not a hard confirmation, but the model does seem to respond faster
when I toggle fast mode on.
Release Notes:
- Added Fast Mode (priority service tier) support to OpenAI models used
through the ChatGPT subscription provider.
Maps the existing `Speed::Fast` plumbing to OpenAI's `service_tier:
"priority"`, which matches what "fast mode" in Codex does. Relevant docs
[here](https://platform.openai.com/docs/api-reference/chat/create#chat-create-service_tier).
Like for the existing Anthropic fast mode we have a
`Model::supports_priority` method for the variants on
https://openai.com/api-priority-processing. Pro, nano, and legacy gpt-4
are excluded; Custom defaults to false.
This is gated to staff only for now (not in this diff, but the existing
fast mode feature), until we have the mechanism to require confirmation
before you enable fast mode.
Release Notes:
- Added support for Fast Mode (priority service tier) on the OpenAI API
provider.
For long threads we will spend more and more time cloning the messages
just to save them to the database, as we need a copy of everything to do
so asynchronously. Messages are really expensive to clone though and we
accumulate a lot of them really fast, so even for smaller threads we
start seeing pauses in the millisecond range. The fix to this is fairly
simple though, we never mutate the messages once pushed to the vec, so
just Arc them.
This PR also slightly changes `UserMessage` to be a bit faster to clone
as well.
Release Notes:
- Fixed a cause of stutters when interacting with the agent
Also makes sure we are properly catching and processing thinking events.

Closes: #56844
Release Notes:
- Added support for specifying effort level when using OpenAI models via
ChatGPT subscription
Adds a new language model provider that lets users authenticate with
their ChatGPT Plus/Pro subscription and use OpenAI models
(codex-mini-latest, o4-mini, o3) directly in the Zed agent — without
needing a separate API key.
## How it works
1. **OAuth 2.0 + PKCE sign-in**: Uses OpenAI's official Codex CLI client
ID to run an authorization code flow. A local HTTP server on
`127.0.0.1:1455` captures the callback, exchanges the code for tokens,
and stores them in the system keychain.
2. **Token refresh**: Access tokens are automatically refreshed when
they're within 5 minutes of expiry, using the stored refresh token.
3. **Responses API**: Requests go to
`https://chatgpt.com/backend-api/codex/responses` using the existing
`open_ai::responses` client (Responses API format, not Chat Completions
which was deprecated for this endpoint in Feb 2026).
4. **Required headers**: `originator: zed`, `OpenAI-Beta:
responses=experimental`, `ChatGPT-Account-Id` (extracted from JWT),
`store: false` in the body.
## Files changed
- `crates/open_ai/src/responses.rs`: Add `store: Option<bool>` field to
`Request`; add `extra_headers` param to `stream_response` for
per-provider header injection
- `crates/language_models/src/provider/openai_subscribed.rs`: New
provider (sign-in UI, OAuth flow, token storage/refresh, model list)
- `crates/language_models/src/provider/open_ai.rs`,
`open_ai_compatible.rs`, `opencode.rs`: Pass `vec![]` for new
`extra_headers` param
- `crates/language_models/src/language_models.rs`: Register the new
provider
- `crates/language_models/Cargo.toml`: Add `rand` and `sha2` deps for
PKCE
## Open questions / known gaps
- [ ] **Terms of service**: Usage appears to be within OpenAI's ToS
(interactive use via their official CLI client ID), but needs legal
sign-off before shipping
- [ ] **Redirect URI**: Currently `http://localhost:1455/auth/callback`
— may need to match exactly what OpenAI's Codex CLI uses
- [ ] **UI polish**: The sign-in card is functional but minimal; needs
design review
- [ ] **Error messages**: OAuth error responses from the callback URL
aren't surfaced to the user yet
- [ ] **`o3` availability**: o3 may require a higher subscription tier;
consider gating it
## Testing
Sign-in flow was designed to match the Copilot Chat provider pattern.
Manual testing against the live OAuth endpoint is needed.
Release Notes:
- Added ChatGPT subscription provider, allowing users to use their
ChatGPT Plus/Pro subscription with the Zed agent

#56472 broke Copilot chat
> Failed to connect to API: 400 Bad Request {"message":"cache_control:
Extra inputs are not permitted"}
This PR makes it so that we still use the legacy caching approach for
Copilot
Release Notes:
- N/A
The Bedrock Converse API supports placing `CachePoint` blocks inside the
`system` field, but we were sending the system prompt as a single
`SystemContentBlock::Text`, which leaves the system tokens dependent on
whatever message-level breakpoint happens to fall within the 20-block
lookback window.
This widens `bedrock::Request.system` from `Option<String>` to
`Vec<BedrockSystemContentBlock>` and has `into_bedrock` emit
`[Text(system), CachePoint(Default)]` whenever the model supports prompt
caching. The system prompt now anchors its own cache prefix, on top of
the existing tool-list anchor and per-message breakpoint, so a stable
system prompt keeps producing cache hits even when earlier conversation
turns change.
Bedrock does not support automatic caching or the 1-hour TTL, so the
default 5-minute ephemeral cache is the only option for this provider.
Release Notes:
- Improved Bedrock prompt cache utilization by anchoring the system
prompt as its own cache prefix
Code had been assuming (erroneously, but understandably) that
LlmApiToken::acquire would give them a valid token.
This is not true, as those tokens expire and you must call refresh
explicitly.
Add some helpers to do the retry for you, and rename acquire to cached
to be
clearer about the intent.
Closes #ISSUE
Release Notes:
- Fixed some rare cases where API requests would fail with Unauthorized
## Background: Amazon Bedrock Guardrails
AWS Bedrock Guardrails enables configurable safety and compliance
controls for generative AI applications:
- Evaluates both user inputs and model responses against policies.
:contentReference[oaicite:8]{index=8}
- Can block or filter content based on harmful categories, denied
topics, PII, or hallucination criteria.
:contentReference[oaicite:9]{index=9}
- Guardrails are applied during inference API calls by specifying
`guardrailIdentifier` and `guardrailVersion` in the request.
:contentReference[oaicite:10]{index=10}
Relevant AWS documentation:
- User Guide:
https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails.html
- How Guardrails Works:
https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-how.html
- API Reference (GuardrailConfiguration):
https://docs.aws.amazon.com/bedrock/latest/APIReference/API_GuardrailConfiguration.html
Some AWS environments enforce IAM policies that require a guardrail to
be specified on every Bedrock API call (via a `StringEquals` condition
on `bedrock:GuardrailIdentifier`). Without this, Zed returns
`AccessDenied` and Bedrock models are completely unusable in those
environments.
This adds two optional settings, `guardrail_identifier` and
`guardrail_version`, to the Bedrock provider config. When set, a
`GuardrailStreamConfiguration` is attached to every `converse_stream`
request. When unset, behaviour is identical to before.
```json
{
"language_models": {
"bedrock": {
"guardrail_identifier": "arn:aws:bedrock:us-east-1:123456789012:guardrail/abc123",
"guardrail_version": "DRAFT"
}
}
}
```
`guardrail_version` defaults to `"DRAFT"` if omitted.
Release Notes:
- agent: Added `guardrail_identifier` and `guardrail_version` settings
for AWS Bedrock, enabling use in environments where IAM policies require
a guardrail on all model requests

When testing the new models and comparing with OpenCode CLI, I realized
the
[variants](https://opencode.ai/docs/models/#built-in-variants)/thinking
effort configuration was not supported by the Zed Agent implementation.
I added that for OpenCode Go models, after manually checking what each
model supports in OpenCode. Reasoning levels and everything seems to
work (UI looks good, model works) but I have no idea how to specifically
test reasoning levels without doing a full benchmark 🤷
I did not add the same thing for OpenCode Zen models because I could not
figure out a way to get the supported variants.
@benbrandt let me know if you want me to take this out of this PR and to
keep just the model updates!
