Did some bit cleanup of code for loading models for settings as that is
not required as we are fetching all the models from openrouter so it's
better to maintain one source of truth
Release Notes:
- Add thinking support to OpenRouter provider
Having `Thread::last_usage` as an override of the initially fetched
usage could cause the initial usage to be displayed when the current
thread is empty or in text threads. Fix is to just store last usage info
in `UserStore` and not have these overrides
Release Notes:
- Agent: Fixed request usage display to always include the most recently
known usage - there were some cases where it would show the initially
requested usage.
Previously, the OpenRouter models list (~412kb) was being downloaded
around 10 times during startup -- even when OpenRouter was not
configured.
This update addresses the issue by:
1. Fetching the models list only when OpenRouter settings change.
2. Skipping API calls if OpenRouter is not configured.
Release Notes:
- Avoid unnecessary requests to OpenRouter
Ran into this while adding support for Vercel v0s models:
- The timestamp seems to be returned in Milliseconds instead of seconds
so it breaks the bounds of `created: u32`. We did not use this field
anywhere so just decided to remove it
- Sometimes the `choices` field can be empty when the last chunk comes
in because it only contains `usage`
Release Notes:
- N/A
The `api_url` setting is one that most providers already support and can
be changed via the `settings.json`. We're adding the ability to change
it via the UI for OpenAI specifically so it can be more easily connected
to v0.
Release Notes:
- agent: Added ability to change the API base URL for OpenAI via the UI

Related to #32888, but will not fix the issue.
Turns out these assertions are wrong (Not sure if they were correct at
some point).
I tested with this code:
```
request = LanguageModelRequest {
messages: vec![
LanguageModelRequestMessage {
role: Role::User,
content: vec![MessageContent::Text("Give me 10 jokes".to_string())],
cache: false,
},
LanguageModelRequestMessage {
role: Role::Assistant,
content: vec![MessageContent::Text("Sure, here are 10 jokes:".to_string())],
cache: false,
},
],
..request
};
```
The API happily accepted this and Claude proceeded to tell me 10 jokes.

Updates google_ai to use latest model information from the respective

Release Notes:
- google: Update to latest Gemini 2.5 models
Previously we were using a mix of `u32` and `usize`, e.g. `max_tokens:
usize, max_output_tokens: Option<u32>` in the same `struct`.
Although [tiktoken](https://github.com/openai/tiktoken) uses `usize`,
token counts should be consistent across targets (e.g. the same model
doesn't suddenly get a smaller context window if you're compiling for
wasm32), and these token counts could end up getting serialized using a
binary protocol, so `usize` is not the right choice for token counts.
I chose to standardize on `u64` over `u32` because we don't store many
of them (so the extra size should be insignificant) and future models
may exceed `u32::MAX` tokens.
Release Notes:
- N/A
We push the usage data whenever we receive it from the provider to make
sure the counting is correct after the turn has ended.

This addresses:
https://github.com/zed-industries/zed/pull/32248#issuecomment-2952060834.
This PR address two main things one allowing enterprise users to use
copilot chat and completion while also introducing the new way to handle
copilot url specific their subscription. Simplifying the UX around the
github copilot and removes the burden of users figuring out what url to
use for their subscription.
- [x] Pass enterprise_uri to copilot lsp so that it can redirect users
to their enterprise server. Ref:
https://github.com/github/copilot-language-server-release#configuration-management
- [x] Remove the old ui and config language_models.copilot which allowed
users to specify their copilot_chat specific endpoint. We now derive
that automatically using token endpoint for copilot so that we can send
the requests to specific copilot endpoint for depending upon the url
returned by copilot server.
- [x] Tested this for checking the both enterprise and non-enterprise
flow work. Thanks to @theherk for the help to debug and test it.
- [ ] Udpdate the zed.dev/docs to refelect how to setup enterprise
copilot.
What this doesn't do at the moment:
* Currently zed doesn't allow to have two seperate accounts as the token
used in chat is same as the one generated by lsp. After this changes
also this behaviour remains same and users can't have both enterprise
and personal copilot installed.
P.S: Might need to do some bit of code cleanup and other things but
overall I felt this PR was ready for atleast first pass of review to
gather feedback around the implementation and code itself.

It works similar to how deepseek works where the thinking is returned as
reasoning_content and we don't have to send the reasoning_content back
in the request.

Recently in this PR: https://github.com/zed-industries/zed/pull/32248
github copilot settings was introduced. This had missing settings update

The info for `max_tokens` for the model is included in
`{api_url}/models`
I don't think this needs to be `.clamp` like in
`crates/ollama/src/ollama.rs` `get_max_tokens`, but it might need to be
## Before:
Every model shows 2k
## After:
### Json from `{api_url}/models` with model not loaded
```json
{
"id": "qwen2.5-coder-1.5b-instruct-mlx",
"object": "model",
"type": "llm",
"publisher": "lmstudio-community",
"arch": "qwen2",
"compatibility_type": "mlx",
"quantization": "4bit",
"state": "not-loaded",
"max_context_length": 32768
},
```
## Notes
The response from `{api_url}/models` seems to return the `max_tokens`
for the model, not the currently configured context length, but I think
showing the `max_tokens` for the model is better than setting 2k for
everything
`loaded_context_length` exists, but only if the model is loaded at the
startup of zed, which usually isn't the case
maybe `fetch_models` should be rerun when swapping lmstudio models
### Currently configured context
this isn't shown in `{api_url}/models`
### Json from `{api_url}/models` with model loaded
```json
{
"id": "qwen2.5-coder-1.5b-instruct-mlx",
"object": "model",
"type": "llm",
"publisher": "lmstudio-community",

Release Notes:
- lmstudio: Fixed showing `max_tokens` in the assistant panel
---------
Co-authored-by: Peter Tripp <peter@zed.dev>
Closes#31491
### Problem
Mistral API enforces strict conversation flow requirements that other
providers don't. Specifically, after a `tool` message, the next message
**must** be from the `assistant` role, not `user`. This causes the
error:
```
"Unexpected role 'user' after role 'tool'"
```
This can also occur in normal conversation flow where mistral doesn't
return the assistant message but that is something which can't be
reproduce reliably.
### Root Cause
When users interrupt an ongoing tool call sequence by sending a new
message, we insert a `user` message directly after a `tool` message,
violating Mistral's protocol.
**Expected Mistral flow:**
```
user → assistant (with tool_calls) → tool (results) → assistant (processes results) → user (next input)
```
**What we were doing:**
```
user → assistant (with tool_calls) → tool (results) → user (interruption) ❌
```
### Solution
Insert an empty `assistant` message between any `tool` → `user` sequence
in the Mistral provider's request construction. This satisfies Mistral's
API requirements without affecting other providers or requiring UX
changes.
### Testing
To reproduce the original error:
1. Start agent chat with `codestral-latest`
2. Send: "Describe this project using tool call only"
3. Once tool calls begin, send: "stop this"
4. Main branch: API error
5. This fix: Works correctly

- Fixed Mistral tool calling in some cases

Release Notes:

This pull request adds full integration with OpenRouter, allowing users
to access a wide variety of language models through a single API key.
**Implementation Details:**
* **Provider Registration:** Registers OpenRouter as a new language
model provider within the application's model registry. This includes UI
for API key authentication, token counting, streaming completions, and
tool-call handling.
* **Dedicated Crate:** Adds a new `open_router` crate to manage
interactions with the OpenRouter HTTP API, including model discovery and
streaming helpers.
* **UI & Configuration:** Extends workspace manifests, the settings
schema, icons, and default configurations to surface the OpenRouter
provider and its settings within the UI.
* **Readability:** Reformats JSON arrays within the settings files for
improved readability.
**Design Decisions & Discussion Points:**
* **Code Reuse:** I leveraged much of the existing logic from the
`openai` provider integration due to the significant similarities
between the OpenAI and OpenRouter API specifications.
* **Default Model:** I set the default model to `openrouter/auto`. This
model automatically routes user prompts to the most suitable underlying
model on OpenRouter, providing a convenient starting point.
* **Model Population Strategy:**
* <strike>I've implemented dynamic population of available models by
querying the OpenRouter API upon initialization.
* Currently, this involves three separate API calls: one for all models,
one for tool-use models, and one for models good at programming.
* The data from the tool-use API call sets a `tool_use` flag for
relevant models.
* The data from the programming models API call is used to sort the
list, prioritizing coding-focused models in the dropdown.</strike>
* <strike>**Feedback Welcome:** I acknowledge this multi-call approach
is API-intensive. I am open to feedback and alternative implementation
suggestions if the team believes this can be optimized.</strike>
* **Update: Now this has been simplified to one api call.**
* **UI/UX Considerations:**
* <strike>Authentication Method: Currently, I've implemented the
standard API key input in settings, similar to other providers like
OpenAI/Anthropic. However, OpenRouter also supports OAuth 2.0 with PKCE.
This could offer a potentially smoother, more integrated setup
experience for users (e.g., clicking a button to authorize instead of
copy-pasting a key). Should we prioritize implementing OAuth PKCE now,
or perhaps add it as an alternative option later?</strike>(PKCE is not
straight forward and complicated so skipping this for now. So that we
can add the support and work on this later.)
* <strike>To visually distinguish models better suited for programming,
I've considered adding a marker (e.g., `</>` or `🧠`) next to their
names. Thoughts on this proposal?</strike>. (This will require a changes
and discussion across model provider. This doesn't fall under the scope
of current PR).
* OpenRouter offers 300+ models. The current implementation loads all of
them. **Feedback Needed:** Should we refine this list or implement more
sophisticated filtering/categorization for better usability?
**Motivation:**
This integration directly addresses one of the most highly upvoted
feature requests/discussions within the Zed community. Adding OpenRouter
support significantly expands the range of AI models accessible to
users.
I welcome feedback from the Zed team on this implementation and the
design choices made. I am eager to refine this feature and make it
available to users.

Hello,
This is my first contribution so apologies if I'm not following the
proper process (I haven't seen anything special in
https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md). Also,
I have tested my changes manually, but I could not figure out an easy we
to instantiate a `LanguageModelSelector` in the unit tests, so I didn't
write a test. If you can provide some guidance I'd be happy to write a
test.

This PR updates how we handle Ollama responses, leveraging the new
[v0.9.0](https://github.com/ollama/ollama/releases/tag/v0.9.0) release.
Previously, thinking text was embedded within the model's main content,
leading to it appearing directly in the agent's response. Now, thinking
content is provided as a separate parameter, allowing us to display it
correctly within the agent panel, similar to other providers. I have
tested this with qwen3:8b and works nicely. ~~We can release this once
the ollama is release is stable.~~ It's released now as stable.

This expands our deserialization of JSON from models to be more tolerant
of different variations that the model may send, including
capitalization, wrapping things in objects vs. being plain strings, etc.
Also when deserialization fails, it reports the entire error in the JSON
so we can see what failed to deserialize. (Previously these errors were
very unhelpful at diagnosing the problem.)
Finally, also removes the `WrappedText` variant since the custom
deserializer just turns that style of JSON into a normal `Text` variant.

**Additional notes:**
I've tried to stick to existing code in OpenAI provider as much as
possible without changing much to keep the diff small.
This PR is done in collaboration with @yagil from LM Studio. We agreed
upon the format in which LM Studio will return information about tool
use support for the model in the upcoming version. As of current stable
version nothing is going to change for the users, but once they update
to a newer LM Studio tool use gets automatically enabled for them. I
think this is much better UX then defaulting to true right now.

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`
