Sergei RazmetovandAnant Goel 7187d65774 language_models: Set support_thinking in Responses API for OpenAI-compatible provider (#59213)
# Objective

Fix OpenAI-compatible reasoning/thinking support. Previously,
`OpenAiCompatibleLanguageModel` never reported thinking support, so
configured `reasoning_effort` values did not reliably reach the wire and
Responses API reasoning state could miss `include:
["reasoning.encrypted_content"]`.

Fixes #58289
Addresses #59207 for OpenAI-compatible Responses models configured with
`reasoning_effort`.

## Solution

- Treat a non-`none` configured `reasoning_effort` as OpenAI-compatible
thinking support.
- Expose common OpenAI-style effort levels in the agent UI, using the
configured effort as the default.
- Honor selected reasoning effort for OpenAI-compatible chat-completions
requests.
- Send `reasoning_effort: "none"` when thinking is disabled for a
configured reasoning model.
- Preserve native OpenAI behavior by continuing to use native
model-specific supported efforts and `max_completion_tokens`.
- Add an OpenAI-compatible `max_tokens_parameter` capability for
endpoints that expect output limits as `max_tokens`.
- Parse common streamed thinking fields (`reasoning` and
`reasoning_content`).
- Add provider setup UI and docs for configuring OpenAI-compatible
reasoning models.

## Testing

- `cargo fmt -p language_model_core -p agent_ui -p language_models`
- `cargo test -p language_models provider::open_ai_compatible::tests
--lib`
- `cargo test -p language_models provider::open_ai::tests --lib`
- `cargo test -p open_ai completion::tests --lib`
- `cargo test -p agent_ui
agent_configuration::add_llm_provider_modal::tests --lib`

kinds:

* fim -- next edit is right under the cursor.
* same-file-near -- next edit is close to the cursor.
* same-file-far -- next edit is more than 30-lines away from cursor.
* cross-file -- next edit is in another file.

Oleksiy SyvokonandEric Holk ade2b219f7 ep: Editable context collectors and metrics (#58400)
This change adds metrics for evaluating editable context collectors and
the collectors themselves:

- `cursor excerpt`: small area around the cursor.
- `current-file`: the full file that contains the cursor.
- `edit-history`: excerpts around edit history edits.
- `edit-history-file`: full files referenced by the edit history.
- `git-log`: files related to the cursor file according to recent git
co-change history.
- `oracle-file`: full files referenced by the expected patches. This is
an oracle/evaluation-only source because it uses the target patch.

Individual collectors can be enabled by passing a comma-separated list
like this: `ep context --type=edit-history,current-file`. There's also a
preset, `--type=editable`, which will enable all collectors except
oracle.

This change also adds the
`.prompt_input.related_files[0].excerpts[0].context_source` field.

Editable context is only accessible via ep-cli for now.

Tom Houlé 5e717a06cd open_ai: Support fast mode in BYOK via the Responses API service_tier (#57412)
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.

Richard FeldmanandMartin Ye ad916ca1af anthropic: Use automatic prompt caching with long-lived anchors on tools and system (#56472)
Switches the Anthropic provider from hand-stamping `cache_control` onto
the last message content block over to Anthropic's top-level automatic
prompt caching, paired with explicit long-TTL (1h) anchors on the last
tool definition and on the system prompt.

The prefix order `tools` → `system` → `messages` satisfies Anthropic's
requirement that longer TTLs appear earlier in the prefix, so the static
prefix is cached for 1h (surviving idle gaps longer than the 5-minute
default) while the rapidly-changing conversation tail uses the
free-to-refresh 5-minute TTL via the top-level automatic breakpoint.
Three of the four available cache breakpoints are used (last tool,
system, automatic conversation), leaving one in reserve.

As a side benefit, this fixes a latent issue where the previous stamping
loop could place `cache_control` on a `Thinking` content block, which
the Anthropic API does not allow. Automatic caching is documented to
walk past ineligible blocks (including thinking) when selecting its
breakpoint, so we now delegate that responsibility to the server.

The new shape we send (when caching is enabled):

```json
{
  "tools": [{ "...": "...", "cache_control": {"type": "ephemeral", "ttl": "1h"} }],
  "system": [
    {"type": "text", "text": "...", "cache_control": {"type": "ephemeral", "ttl": "1h"}}
  ],
  "messages": [ /* no per-block cache_control */ ],
  "cache_control": {"type": "ephemeral"}
}
```

Release Notes:

- Improved Anthropic prompt cache utilization, reducing latency and cost
for ongoing conversations

https://github.com/ggml-org/llama.cpp/issues/20837.

In my testing, enabling interleaved_reasoning not only resolved the
tool-calling issues encountered by Qwen3.5 models in llama.cpp, but also
appeared to improve the model's coding capabilities. I have also
verified the outgoing requests using a proxy to ensure the parameter is
being sent correctly.It is also likely that this change will benefit
other models and providers as well.

Note: While I used AI to assist with the implementation, I have reviewed
and tested the changes. As I am relatively new to Rust and the Zed
codebase, I would appreciate any feedback or suggestions for
improvement. I am happy to make further adjustments if needed.

Thank you all for building such an amazing editor!

Oleksiy Syvokon c788dc5217 ep: Add LCS-based recall (#53509)
This PR adds the `correctly_deleted_chars` field and updates `kept_rate`
to account for it, not just inserted chars.

It also adds `recall_rate` to measure coverage of reference
insertions/deletions.

Finally, it renames "final" to "reference" and "prediction" to
"candidate".

Jakub Konka 29609d3599 language_model: Decouple from Zed-specific implementation details (#52913)
This PR decouples `language_model`'s dependence on Zed-specific
implementation details. In particular
* `credentials_provider` is split into a generic `credentials_provider`
crate that provides a trait, and `zed_credentials_provider` that
implements the said trait for Zed-specific providers and has functions
that can populate a global state with them
* `zed_env_vars` is split into a generic `env_var` crate that provides
generic tooling for managing env vars, and `zed_env_vars` that contains
Zed-specific statics
* `client` is now dependent on `language_model` and not vice versa

Oleksiy Syvokon 66ea4b89af ep: Move pure diffing functions to zeta_prompt:udiff (#52959)
This PR mostly moves some code around. It also adds a high-level
`format_expected_output` function that routes patch formatting to
specific prompt formats. This was `zeta_prompt` can format
`expected_output` for training.

Keeping everything prompt-related in a "pure" module (with no heavy
dependencies) makes it easier to write bindings.

3ce0cd11ec Extract language_core and grammars crates from language (#52238)
This extracts a `language_core` crate from the existing `language`
crate, and creates a `grammars` data crate. The goal is to separate
tree-sitter grammar infrastructure, language configuration, and LSP
adapter types from the heavier buffer/editor integration layer in
`language`.

## Motivation

The `language` crate pulls in `text`, `theme`, `settings`, `rpc`,
`task`, `fs`, `clock`, `sum_tree`, and `fuzzy` — all of which are needed
for buffer integration (`Buffer`, `SyntaxMap`, `Outline`,
`DiagnosticSet`) but not for grammar parsing or language configuration.
Extracting the core types lets downstream consumers depend on
`language_core` without pulling in the full integration stack.

## Dependency graph after extraction

```
language_core   ← gpui, lsp, tree-sitter, util, collections
grammars        ← language_core, rust_embed, tree-sitter-{rust,python,...}
language        ← language_core, text, theme, settings, rpc, task, fs, ...
languages       ← language, grammars
```

## What moved to `language_core`

- `Grammar`, `GrammarId`, and all query config/builder types
- `LanguageConfig`, `LanguageMatcher`, bracket/comment/indent config
types
- `HighlightMap`, `HighlightId` (theme-dependent free functions
`highlight_style` and `highlight_name` stay in `language`)
- `LanguageName`, `LanguageId`
- `LanguageQueries`, `QUERY_FILENAME_PREFIXES`
- `CodeLabel`, `CodeLabelBuilder`, `Symbol`
- `Diagnostic`, `DiagnosticSourceKind`
- `Toolchain`, `ToolchainScope`, `ToolchainList`, `ToolchainMetadata`
- `ManifestName`
- `SoftWrap`
- LSP data types: `BinaryStatus`, `ServerHealth`,
`LanguageServerStatusUpdate`, `PromptResponseContext`, `ToLspPosition`

## What stays in `language`

- `Buffer`, `BufferSnapshot`, `SyntaxMap`, `Outline`, `DiagnosticSet`,
`LanguageScope`
- `LspAdapter`, `CachedLspAdapter`, `LspAdapterDelegate` (reference
`Arc<Language>` and `WorktreeId`)
- `ToolchainLister`, `LanguageToolchainStore` (reference `task` and
`settings` types)
- `ManifestQuery`, `ManifestProvider`, `ManifestDelegate` (reference
`WorktreeId`)
- Parser/query cursor pools, `PLAIN_TEXT`, point conversion functions

## What the `grammars` crate provides

- Embedded `.scm` query files and `config.toml` files for all built-in
languages (via `rust_embed`)
- `load_queries(name)`, `load_config(name)`,
`load_config_for_feature(name, grammars_loaded)`, and `get_file(path)`
functions
- `native_grammars()` for tree-sitter grammar registration (behind
`load-grammars` feature)

## Pre-cleanup (also in this PR)

- Removed unused `Option<&Buffer>` from
`LspAdapter::process_diagnostics`
- Removed unused `&App` from `LspAdapter::retain_old_diagnostic`
- Removed `fs: &dyn Fs` from `ToolchainLister` trait methods
(`PythonToolchainProvider` captures `fs` at construction time instead)
- Moved `Diagnostic`/`DiagnosticSourceKind` out of `buffer.rs` into
their own module

## Backward compatibility

The `language` crate re-exports everything from `language_core`, so
existing `use language::Grammar` (etc.) continues to work unchanged. The
only downstream change required is importing `CodeLabelExt` where
`.fallback_for_completion()` is called on the now-foreign `CodeLabel`
type.

Release Notes:

- N/A
