053c368ba4 fix(core): remove Bedrock prevalidation from load (#37909) 
Removes the built-in Bedrock class init validator from `load` so Bedrock
kwargs such as `base_url` and `endpoint_url` are no longer specially
rejected during deserialization.

This keeps provider-specific SSRF policy out of core; callers should
continue to avoid untrusted manifests or use restrictive
`allowed_objects`.

Verified with `make format`, `make lint`, and the focused serialization
load unit tests.

<h2>1.0.0rc1 (February 23, 2026)</h2>
<p>We're ready! I'm thrilled to announce the first release candidate for
Starlette 1.0.</p>
<p>Starlette was created in June 2018 by Tom Christie, and has been on
ZeroVer for years. Today, it's downloaded
almost <a href="https://pypistats.org/packages/starlette">10 million
times a day</a>, serves as the foundation for FastAPI,
and has inspired many other frameworks. In the age of AI, Starlette
continues to play an important role as a
dependency of the Python MCP SDK.</p>
<p>This release focuses on removing deprecated features that were marked
for removal in 1.0.0, along with some
last minute bug fixes. It's a release candidate, so we can gather
feedback from the community before the final
1.0.0 release soon.</p>
<p>A huge thank you to all the contributors who have helped make
Starlette what it is today.
In particular, I'd like to recognize:</p>
<ul>
<li><a href="https://github.com/lovelydinosaur">Kim Christie</a> - The
original creator of Starlette, Uvicorn, and MkDocs, and the
current maintainer of HTTPX. Kim's work helped lay the foundation for
the modern async Python ecosystem.</li>
<li><a href="https://github.com/adriangb">Adrian Garcia Badaracco</a> -
One of the smartest people I know, whom I have the pleasure of working
with at Pydantic.</li>
<li><a href="https://github.com/graingert">Thomas Grainger</a> - My
async teacher, always ready to help with questions.</li>
<li><a href="https://github.com/agronholm">Alex Grönholm</a> - Another
async mentor, always prompt to help with questions.</li>
<li><a href="https://github.com/florimondmanca">Florimond Manca</a> -
Always present in the early days of both Starlette and Uvicorn, and
helped a lot in the ecosystem.</li>
<li><a href="https://github.com/aminalaee">Amin Alaee</a> - Contributed
a lot with file-related PRs.</li>
<li><a href="https://github.com/tiangolo">Sebastián Ramírez</a> -
Maintains FastAPI upstream, and always in contact to help with upstream
issues.</li>
<li><a href="https://github.com/alex-oleshkevich">Alex Oleshkevich</a> -
Helped a lot on templates and many discussions.</li>

586bcd46a1 docs(core): expand and link ModelProfile docstrings (#37904) 
Rewrote the `ModelProfile` docstrings to point readers at canonical
docs. The class docstring now explains how profiles are accessed and
where the data comes from, and several terse field docstrings gain a
one-line clarification or a link to the relevant guide.

3b999176c8 test(langchain,partners): disable pytest-benchmark under xdist to silence PytestBenchmarkWarning (#37901) 
Test targets run with `-n auto`, which makes `pytest-benchmark` (present
via `langchain-tests`) auto-disable itself and emit a
`PytestBenchmarkWarning` once per xdist worker. Passing
`--benchmark-disable` turns the plugin off explicitly so the warning
never fires, matching what `core` and `langchain_v1` already do.

## Changes
- Add `--benchmark-disable` to the `-n auto` test targets across
`langchain` (unit) and 14 partner packages' integration targets:
`anthropic`, `chroma`, `deepseek`, `exa`, `fireworks`, `groq`,
`huggingface`, `mistralai`, `nomic`, `ollama`, `openai`, `openrouter`,
`qdrant`, `xai`.
- Deliberately excluded `text-splitters` and `model-profiles`: their
`test` group doesn't install `pytest-benchmark`, so the flag would fail
with `unrecognized arguments`. Verified by importing the plugin under
each package's actual dependency group before editing.

34af59c1a6 fix(partners): cap aiohttp below 3.14 for vcrpy compat (#37898) 
aiohttp **3.14.0** (released 2026-06-01) removed
`aiohttp.streams.AsyncStreamReaderMixin`. The current release of `vcrpy`
(8.1.1) still subclasses it in its aiohttp stub:

```python
class MockStream(asyncio.StreamReader, streams.AsyncStreamReaderMixin):
```

As a result, the VCR fixture fails to import during test setup, and the
scheduled integration tests for the `fireworks` and `xai` partners error
out at `test_stream_time`:

```
AttributeError: module 'aiohttp.streams' has no attribute 'AsyncStreamReaderMixin'
```

Only these two partners are affected because their SDKs use `aiohttp`,
so VCR loads its aiohttp stub; partners on `httpx` (e.g. `anthropic`,
`openai`) are unaffected.

This is an upstream incompatibility tracked at kevin1024/vcrpy#995, with
a fix in kevin1024/vcrpy#996 that has not yet been released.

Until a fixed `vcrpy` ships, this caps `aiohttp<3.14.0` via `[tool.uv]
constraint-dependencies` (the same mechanism already used for the
`pygments` CVE pin) in both packages. Using a constraint rather than
tightening the published `aiohttp>=3.9.1,<4.0.0` range means the change
only affects local/CI resolution — the package metadata users install
against is untouched. Both lockfiles re-resolve to `aiohttp` 3.13.5,
which still provides the removed attribute. A code comment points back
to the upstream fix so the pin can be removed once it lands.

bae485bd5e chore: bump dependencies (#37892) 
## Summary
- Bump `langsmith` in `libs/partners/huggingface/uv.lock` from 0.7.31 to
0.8.9
- Bump `langchain-classic` in `libs/langchain_v1/uv.lock` from 1.0.0 to
1.0.7
- Bump transitive `langsmith` in `libs/langchain_v1/uv.lock` from 0.8.0
to 0.8.9

## Notes
- The open Chroma alert currently has no patched version in GitHub
Dependabot metadata. `chromadb` is already at 1.5.9 on `master`, and
PyPI shows 1.5.9 as the latest available release.

## Testing
- `uv lock --check` in `libs/partners/huggingface`
- `uv lock --check` in `libs/langchain_v1`
- `uv lock --check` in `libs/partners/chroma`
- `git diff --check`

17d1c274c4 fix(langchain): improve HITL rejection guidance (#37859) 
Improves the default `reject` `ToolMessage` so models see that the human
denied the action, the tool was not executed, and the same call should
not be retried unless the user asks. Also documents that clients can
provide a custom `reject` message for domain-specific guidance.

36be77b0f1 feat(langchain): add interrupt_mode and when predicate to HumanInTheLoopMiddleware (#37579) 
Adds an optional `when` predicate to `InterruptOnConfig`, allowing
dynamic per-tool-call control over whether a HITL interrupt fires.

---

**`when` predicate in `InterruptOnConfig`**

```python
class InterruptOnConfig(TypedDict):
    allowed_decisions: list[DecisionType]
    description: NotRequired[str | _DescriptionFactory]
    args_schema: NotRequired[dict[str, Any]]
    when: NotRequired[Callable[[ToolCallRequest], bool]]  # new
```

When provided, `when` is called before adding a tool call to the batch
interrupt. If it returns `False`, the call is auto-approved and
excluded. If it returns `True` (or `when` is absent), existing behaviour
is unchanged.

The predicate receives a `ToolCallRequest` with:
- `tool_call` — the raw tool call dict (name, args, id)
- `tool` — `None` (no `BaseTool` instance is available at the
`after_model` stage)
- `state` — current agent state
- `runtime` — a `ToolRuntime` constructed from the node-level `Runtime`,
with `tool_call_id` populated

Example:

```python
HumanInTheLoopMiddleware(
    interrupt_on={
        "delete_file": InterruptOnConfig(
            allowed_decisions=["approve", "reject"],
            when=lambda req: req.tool_call["args"].get("path", "").startswith("/etc"),
        )
    }
)
```

This change is fully backwards-compatible — `when` is `NotRequired` and
existing configs without it behave identically.

1a5403d848 fix(anthropic): normalize cross-provider tool-call IDs (#37756) 
Anthropic's API rejects `tool_use`/`tool_result` IDs that don't match
`^[a-zA-Z0-9_-]+$` with a 400. When a conversation thread is replayed
across providers — e.g. a user switches a running thread from Kimi (via
Fireworks) to Claude — the prior turns carry tool-call IDs minted by the
other provider (Kimi emits `functions.write_todos:0`, whose `.` and `:`
are invalid), and the request fails. Tool-call IDs are now normalized to
an Anthropic-compatible form during request formatting, with the
original `tool_use.id` and its paired `tool_use_id` mapped identically
so they stay linked.

8951e5666f chore(perplexity): bump perplexityai to 0.34.1 (#37710) 
## Description
Bumps `langchain-perplexity` to require the Perplexity SDK release with
fixed Responses streaming and removes the temporary SSE shim workaround.

## Release Note
`langchain-perplexity` now requires `perplexityai>=0.34.1` for Responses
API streaming.

## Test Plan
- [x] `NO_COLOR=1 uv run --group test pytest
tests/unit_tests/test_chat_models_responses.py --disable-socket
--allow-unix-socket`

_Opened collaboratively by Mason Daugherty and open-swe._

e3ce6e557c fix(fireworks): strip non-wire keys from all content parts before serialization (#37714) 
`_sanitize_chat_completions_content` now filters every content-part dict
against an allowlist derived at import time from the `fireworks-ai`
SDK's `ContentUnionMember1` TypedDict, and runs on every message role —
not just `ToolMessage`. Fixes 400s of the form `Extra inputs are not
permitted, field:
'messages[N].content.list[ChatMessageContent][i].<key>'` when
cross-provider history (e.g. an Anthropic-shaped `AIMessage` carrying
the v1 streaming-reassembly `index` marker) is forwarded to a
Fireworks-hosted model.

f9be3cc328 feat(perplexity): use_responses_api flag on ChatPerplexity (#37359) 
Closes #37360

Adds a `use_responses_api` flag to `ChatPerplexity` so requests can be
routed through Perplexity's Agent API (the Perplexity-flavored Responses
API) in addition to the existing Chat Completions endpoint. This mirrors
the `use_responses_api` flag on `ChatOpenAI`.

## Motivation

Perplexity exposes two HTTP surfaces from the same SDK client object:
`client.chat.completions.create()` (Chat Completions) and
`client.responses.create()` (Agent API, OpenAI-compatible Responses
shape). The Agent API supports built-in tools (`web_search`,
`fetch_url`, `finance_search`, `people_search`), `instructions`,
`input`, `previous_response_id`, and `include` — none of which exist on
Chat Completions. Today `ChatPerplexity` only calls Chat Completions, so
users who want the Agent API have to drop down to the raw SDK.

## What this changes

- New field `use_responses_api: bool | None = None` on `ChatPerplexity`.
- New module-level helper `_use_responses_api(payload)` that returns
`True` when the payload contains a built-in tool (any `tools[*]` whose
`type` is not `"function"`) or any of the Responses-only fields
`previous_response_id`, `instructions`, `input`, `include`.
- New instance method `ChatPerplexity._use_responses_api(payload)` that
honors `self.use_responses_api` when it is a `bool`, otherwise delegates
to the module helper.
- New converters `_convert_responses_to_chat_result(response)` and
`_convert_responses_stream_event_to_chunk(event)` that translate Agent
API objects/events into `AIMessage` and `AIMessageChunk` (preserving
`usage_metadata`, `response_metadata`, citations, images, related
questions, search results, and `function_call` tool calls).
- A surgical `_to_responses_payload(...)` helper that renames `messages`
→ `input` and `max_tokens` → `max_output_tokens`, passes through
Responses-supported fields, and parks anything Perplexity-specific under
`extra_body`.
- Each of the four API call sites (`_stream`, `_astream`, `_generate`,
`_agenerate`) now branches on `self._use_responses_api(payload)`. The
Chat Completions path is untouched.

## Auto-detection rules

When `use_responses_api` is unset (the default), routing is decided per
call from the outgoing payload:

- Has a built-in tool? → Responses
- Has `previous_response_id`, `instructions`, `input`, or `include`? →
Responses
- Otherwise → Chat Completions

Explicit `use_responses_api=True` or `=False` always overrides
auto-detection.

## Backwards compatibility

Existing usage is unchanged.
`ChatPerplexity(model="sonar").invoke("hi")` still calls
`client.chat.completions.create()`. No public field was renamed or
removed; the new field is purely additive.

## Tests

Adds `tests/unit_tests/test_chat_models_responses.py` covering the
helper, auto-detect routing, explicit overrides in both directions,
response-to-`AIMessage` conversion (content, `usage_metadata`,
`response_metadata.id`), `function_call` → `tool_calls` conversion, and
sync + async streaming of `response.output_text.delta` and
`response.completed` events. All mocks use `MagicMock`/`AsyncMock`; no
network calls.

## Notes for reviewers

This was implemented with help from an AI agent. The shape mirrors
`langchain-openai`'s `use_responses_api` — same field name, same helper
name, same docstring style — so the diff should be familiar.

Closes nothing — net new feature.

7bb4130c7d chore(langchain): bump to 1.3.2, require langgraph>=1.2.2 (#37703) 
- Bumps `langchain` to **1.3.2** (patch)
- Raises minimum `langgraph` requirement from `>=1.2.1` to `>=1.2.2`

langgraph 1.2.2 fixes a race condition where DeltaChannel checkpoint
writes
could serialize `BaseMessage` objects with `id=None` before
`apply_writes()`
ran the reducer, causing the same message to appear with a different ID
on
every `get_state()` call and across resumed invocations
(langchain-ai/langgraph#7913).

The lockfile will be updated once langgraph 1.2.2 is published to PyPI
(langchain-ai/langgraph#7914).

95c6a8aa76 chore(core): bump uuid-utils to 0.16.0 (#37699) 
Refresh `langchain-core`'s lockfile so the dev/CI environment resolves
`uuid-utils` to a release that ships free-threading wheels (`cp313t`,
`cp314t`). Unblocks `pip install` on Python 3.14 free-threaded builds —
previously the lock pinned `0.14.1`, which had no FT wheel and forced an
sdist build. Related to #34870.

c7858c46d8 test(anthropic): retry integration tests on transient failures (#37697) 
Enable `pytest-retry` on the `integration_tests` Make target so live API
flakes (e.g. `test_batch` timing out against `api.anthropic.com`) no
longer fail the job on first miss. Matches the existing convention in
`libs/partners/groq`.
