docs: refresh README installation and resources (#38119)
README installation examples now use `uv add` consistently, matching the repo's `uv`-based Python workflow. The top-level README also gets a cleaner quickstart and resource section with current links for docs, community, learning, and contribution guidance. ## Changes - Replaced `pip install` snippets with `uv add` across package quick install docs, including the Hugging Face extras and `sentence-transformers` upgrade examples. - Updated the top-level quickstart to show only `uv add langchain` and refreshed the example model to `openai:gpt-5.5`. - Pointed the LangGraph orchestration link at the LangGraph GitHub repository. - Consolidated top-level documentation and additional-resource links under a single `Resources` section covering docs, ecosystem overview, API reference, discussions, Academy, contributing, and the Code of Conduct. - Added LangChain Academy and Code of Conduct links to package README resource sections. |

release(core): 1.4.7 (#38111)
Bumps `langchain-core` to `1.4.7` for the next patch release and updates downstream minimum `langchain-core` requirements so package locks resolve against the new core version. This also refreshes the runnable snapshots that embed `lc_versions` metadata so the version consistency check continues to validate checked-in artifacts. Validated with `python libs/core/scripts/check_version.py`, `uv lock --check` across package lockfiles, and the core runnable tests that own the updated snapshots with local LangSmith tracing env disabled. |

fix(core,partners): rename package version trace metadata (#38110)
Package-version trace metadata now uses the LangChain-owned `metadata["lc_versions"]` convention instead of the user-owned `metadata["versions"]` key. Metadata merging is narrowed so only `lc_versions` accumulates nested package-version entries, while generic nested metadata keeps normal last-writer-wins behavior. ## Changes - Renamed `BaseLanguageModel._add_version()` trace metadata from `versions` to `lc_versions`, including docstrings and the non-dict replacement warning. - Scoped `_merge_metadata_dicts()` nested-map accumulation to only `lc_versions`; duplicate package entries remain last-writer-wins and `lc_versions` mappings are copied defensively. - Preserved user-owned `metadata["versions"]` semantics by keeping it out of package-version tracking and generic nested metadata merging. - Updated runnable snapshots and partner package metadata assertions across Anthropic, DeepSeek, Fireworks, Groq, Hugging Face, MistralAI, Ollama, OpenAI, OpenRouter, Perplexity, and xAI to expect `lc_versions`. ## Testing - Added/adjusted core tests for `lc_versions` accumulation, duplicate package overwrite behavior, non-dict `lc_versions` replacement, defensive copying, and `metadata["versions"]` last-writer-wins behavior. - Ran focused core and partner metadata tests plus Ruff checks for changed areas. |

style(core,langchain,langchain-classic,partners): replace double backticks in docstrings (#38095)
Standardizes inline code markup in Python docstrings and comments by replacing Sphinx-style double backticks with single-backtick Markdown. The cleanup keeps existing code fences intact while aligning inline references with the repo's docstring convention. ## Changes - Converted inline code references in core prompt-loading docs and LangSmith tracer comments, including `..`, `allow_dangerous_paths`, and inheritable metadata keys. - Normalized agent-related docstrings and comments around `wrap_model_call`, `ExtendedModelResponse`, `Command`, `create_structured_chat_agent`, and `DockerExecutionPolicy`. - Updated partner package docstrings for inline references such as `json_schema`, `ToolCall`, `apply_patch_call_output`, OpenRouter content block keys, and Perplexity tool-call serialization. - Cleaned test and helper docstrings that referenced command separators, fake `resource` modules, stream event names, and xdist rate-limit environment variables. |

feat(core,partners): add package version tracking to tracing metadata (#35295)
Following on the heels of #35293 TODO: - Packages outside of this repo (e.g. LiteLLM, Nvidia, Google, AWS) --- ## Summary Surface partner package versions in `metadata.versions` on LangSmith traces. Mirrors the JS SDK's `_addVersion()` pattern ([langchainjs#10106](https://github.com/langchain-ai/langchainjs/pull/10106)). Each model constructor records its package version via `_add_version()` on `BaseLanguageModel`. The version dict accumulates through the class hierarchy — `langchain-core` is added in `BaseLanguageModel.model_post_init`, `langchain-openai` in `BaseChatOpenAI._set_openai_chat_version`, and each leaf partner in its uniquely-named `model_validator`. Traces end up with: ```json { "metadata": { "versions": { "langchain-core": "1.4.5", "langchain-openai": "1.3.0", "langchain-xai": "1.2.2" } } } ``` ### Changes - `BaseLanguageModel._add_version(pkg, version)` — appends to `self.metadata["versions"]`; accepts any `Mapping` type; emits a warning if a non-mapping value is found and replaced - `BaseLanguageModel.model_post_init` — adds `langchain-core` version; calls `super()` for MRO safety - `_merge_metadata_dicts` — one-level-deep (non-recursive) merge for nested dict metadata keys - `CallbackManager.add_metadata` — uses `_merge_metadata_dicts` instead of flat `dict.update()` so nested metadata dicts (like `versions`) coexist rather than clobber - `merge_configs` — uses `_merge_metadata_dicts` for config merging **Partners:** - Each now calls `self._add_version("langchain-<pkg>", __version__)` ### Design decisions - **Constructor-based, not `_get_ls_params`-based** — versions flow through `self.metadata` (local metadata on traces), not through `LangSmithParams`. This matches JS and makes child-class version inheritance automatic (no merge/clobber issues). - **`versions` is local (non-inheritable) metadata** — `self.metadata` is passed to `CallbackManager.configure` as `local_metadata` (`add_metadata(..., inherit=False)`), so `versions` is attached **once per chat-model run** and is **not** propagated to child runs or duplicated onto every streaming chunk. This is intentionally the opposite of the inheritable-per-chunk metadata that #36588 was reducing for performance — `versions` does not regress that path. - **`add_metadata` deep-merge is a correctness fix, not just for versions** — previously `add_metadata`/`merge_configs` did a flat top-level `dict.update`/spread, so any nested metadata dict baked into a config (e.g. via `.with_config({"metadata": {...}})`) would be wholly replaced when a caller also passed `metadata`. `_merge_metadata_dicts` merges one level deep so user-provided `config.metadata.versions` and model-set `versions` coexist instead of clobbering. The merge runs once per `configure` (not per chunk), so it is off the streaming hot path. - **One level deep only** — `_merge_metadata_dicts` is deliberately *not* a recursive deep merge; values nested more than one level are last-writer-wins. This covers the `versions` case without the ambiguity/cost of arbitrary-depth merging. - **Warn on non-dict `metadata["versions"]`** — if a user sets `metadata={"versions": "some-string"}`, `_add_version` emits a warning and replaces the value with the version dict rather than silently discarding user data or crashing. This is a soft breaking change for anyone who previously stored non-dict values at this key. ### Follow-ups (tracked separately, out of scope here) - JS `mergeConfigs` still flat-spreads nested metadata, so `metadata.versions` can still clobber on the JS side until an equivalent deep-merge lands. --- Made by [Open SWE](https://openswe.vercel.app) --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> |

chore(infra): bump mypy to 2.1 and unify type-check config across the monorepo (#36470)
Originally a narrow bump of mypy to `1.20` in four packages. Expanded to get the whole monorepo onto a single, current mypy and a consistent type-check configuration, so contributors no longer hit different mypy versions and divergent behavior depending on which package they touch. ### What changed - **Unified the mypy pin to `>=2.1.0,<2.2.0`** in every mypy-using package (6 libs + 14 partners), replacing the previously scattered pins (`1.10`/`1.17`/`1.18`/`1.19`/`1.20`, with assorted upper bounds). - **Unified the `[tool.mypy]` base per tier:** - libs: `plugins = ["pydantic.mypy"]`, `strict = true`, `enable_error_code = "deprecated"`, `warn_unreachable = true` - partners: `disallow_untyped_defs = true` - Normalized style (`disallow_untyped_defs = "True"` string → bool, quote/key consistency). - **Fixed the 20 real errors** mypy 2.1 surfaces: `redundant-cast` from improved narrowing (`core`, `langchain-classic`), a `var-annotated` for `_LOGGED`, a return-type widening in `langchain-groq`'s `_convert_from_v1_to_groq` (it can legitimately return a bare `str`), and stale `type-arg`/`unused-ignore` in `langchain-model-profiles` tests. ### Deliberate non-uniformity (documented inline in the relevant `pyproject.toml`s) Going fully byte-identical would surface ~196 additional errors that are *not* real bugs, so two settings are kept package-appropriate: - **`warn_unreachable`** is enabled on every strict lib **except `core`**, where it false-flags intentional defensive code — including the SSRF / IP-policy guards in `_security/` — as unreachable. - **`pydantic.mypy` plugin** is used only on `anthropic` and `perplexity` (their code is authored against it and reports ~99/~132 errors without it). It is *not* added to the other partners, where it only flags the public alias constructor API (e.g. `ChatGroq(model=...)`) in tests rather than finding bugs. - **`ollama`** is left on its `ty` type checker; it does not use mypy. --------- Co-authored-by: Mason Daugherty <github@mdrxy.com> |

feat(standard-tests): validate tool call chunks during streaming (#34707)
As a LangChain user streaming a tool-calling model, I expect each streamed chunk to expose structured `tool_call_chunk` content blocks so I can render or process tool calls live, instead of waiting for the final aggregated message. This adds `tool_call_streaming` to `ModelProfile` and uses it in the standard chat-model tool-calling tests. When a model profile opts in, `test_tool_calling` and `test_tool_calling_async` now validate that at least one streamed chunk includes a `tool_call_chunk` block via `content_blocks`, while preserving the existing final-message validation. This keeps the contract profile-gated so providers can opt in once their streaming chunk shape is verified. This PR opts in the providers verified by smoke testing with straightforward profile coverage: OpenAI, Anthropic, Fireworks, HuggingFace, OpenRouter, DeepSeek, and xAI. The generated profile artifacts are refreshed so runtime profiles expose the new capability flag. Perplexity Responses also passed the smoke test, but its current profile data is for the `sonar` family while the Responses smoke path used a routed model string. That profile strategy is left as follow-up. MistralAI currently streams `.tool_call_chunks`, but its content-block translator exposes a complete `tool_call` block instead of `tool_call_chunk`, so it also stays out of this flag until that integration is fixed. |

feat(perplexity): bind_tools and Responses-API tool round-trip (#37934)
## Summary Follow-up to #37911 (released in `langchain-perplexity` 1.3.2). That PR fixed the outbound `ToolMessage` / `AIMessage.tool_calls` serialization; this one implements **`ChatPerplexity.bind_tools`**, which flips `has_tool_calling` to `True` and lights up the full `langchain-tests` standard tool-calling suite — the suite that would have caught #37911 in the first place. Verified live against the Perplexity Agent API (`openai/gpt-5.5`, `use_responses_api=True`): a client-side function-tool round-trip (invoke + stream) works end-to-end. ## Core change (the `bind_tools` work + the Responses-API follow-up) - **`bind_tools`** mirrors `langchain-openai`: converts tools via `convert_to_openai_tool`, normalizes `tool_choice`, and passes Perplexity built-in tools (`web_search`, etc.) through unchanged. - **`_to_responses_payload`** now translates tool turns into the Responses (Agent) API's typed input items: `AIMessage.tool_calls` → `function_call`, `ToolMessage` → `function_call_output`, and flattens function tool specs. (The Responses API has no `tool` role, so this translation is required for round-trips.) ## Changes required to make standard-suite tests pass on the Responses route - Streaming: `_convert_responses_stream_event_to_chunk` emits a `tool_call_chunk` on `response.output_item.done` function calls — required by `test_tool_calling` (which streams and asserts tool calls). - `_content_to_text` reduces list-shaped assistant content to text in the tool-call branch — required by `test_agent_loop` and `test_tool_message_histories_list_content`. - `response_metadata["model_name"]` on the Responses route, mirroring Chat Completions — required by `test_usage_metadata` / `test_usage_metadata_streaming` (used by `langchain_core` usage callbacks). ## Tests - `sonar` standard class marked `has_tool_calling=False` (the family returns 400 "Tool calling is not supported for this model"). - New `TestPerplexityResponsesStandard` runs the full suite on `openai/gpt-5.5` + `use_responses_api` with `has_tool_choice=False`: **35 passed, 13 skipped, 2 xfailed**. - The 2 xfails (`test_unicode_tool_call_integration`, `test_structured_few_shot_examples`) hard-code `tool_choice="any"`. The Responses (Agent) API does not support `tool_choice` (verified: every form returns HTTP 200 without forcing a call), which `ChatPerplexity` surfaces as `ValueError` — **existing behavior, unchanged here.** Softening that to a warning can be a separate change. `make format lint` clean; unit + standard tests green. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

fix(perplexity): serialize ToolMessage and AIMessage.tool_calls (#37911)
Fixes #37912 `ChatPerplexity._convert_message_to_dict` raises `TypeError` on `ToolMessage` and drops `AIMessage.tool_calls`, which breaks tool-message round-trips through `ChatPerplexity` — a client-side tool-calling loop, or a shared message history across providers via `RunnableWithFallbacks`. Repro: ```python from langchain_perplexity import ChatPerplexity from langchain_core.messages import ToolMessage ChatPerplexity(model="sonar")._convert_message_to_dict( ToolMessage(content="result", tool_call_id="call_1") ) # TypeError: Got unknown type content='result' tool_call_id='call_1' ``` An `AIMessage` carrying `tool_calls` also serializes to `{"role": "assistant", "content": ...}` with the `tool_calls` silently dropped. This brings the converter to parity with `langchain-openai`: serialize `tool_calls` / `invalid_tool_calls`, send `content` as `null` when tool_calls are present, and add a `tool`-role branch for `ToolMessage`. How I verified: added unit tests for the `ToolMessage` and `AIMessage.tool_calls` / `invalid_tool_calls` cases; the perplexity package unit tests, lint, and format all pass. Scope: translating these to the Responses (Agent) API's `function_call` / `function_call_output` input items is a separate follow-up; this PR is the Chat Completions serialization parity fix. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

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. --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

ci(infra): harden Dependabot version-bound preservation (#37510)
Dependabot has been stripping upper/lower bounds from internal `langchain-*` deps in partner `pyproject.toml` files (e.g. #37288 reduced `langchain-core>=1.3.2,<2.0.0` to bare `langchain-core`). Locks down the config so bumps preserve existing specifiers, and restores the bounds it already mangled across the monorepo. ## Changes - Add `versioning-strategy: increase` to every `uv` ecosystem block in `.github/dependabot.yml` so future bumps move the lower bound in place instead of rewriting the constraint. - Ignore workspace-internal packages (`langchain-core`, `langchain`, `langchain-classic`, `langchain-text-splitters`, `langchain-tests`, `langchain-model-profiles`) on every `uv` block — these are editable installs from local paths and their published constraints are hand-curated for release, not Dependabot's to bump. - Restore stripped bounds across all `libs/` packages — runtime `dependencies` and every dep group (`test`, `dev`, `test_integration`, `typing`, `lint`) — to `>=1.4.0,<2.0.0` for `langchain-core` and `>=1.0.0,<2.0.0` for the other internal packages. |

feat(perplexity): add PerplexityEmbeddings (#37082)
## Description This PR adds a new `PerplexityEmbeddings` class to the `langchain-perplexity` partner package, providing first-class support for the Perplexity Embeddings API alongside the existing `ChatPerplexity`, `PerplexitySearchRetriever`, and `PerplexitySearchResults` integrations. ### What was added - `langchain_perplexity/embeddings.py` — `PerplexityEmbeddings` class implementing `langchain_core.embeddings.Embeddings` with sync (`embed_documents`, `embed_query`) and async (`aembed_documents`, `aembed_query`) methods. Defaults to model `pplx-embed-v1-4b` and reuses the existing `_utils.initialize_client` helper for API key resolution (`PPLX_API_KEY` / `PERPLEXITY_API_KEY`). - `__init__.py` exports `PerplexityEmbeddings` and adds it to `__all__`. - Unit tests under `tests/unit_tests/test_embeddings.py` covering sync/async paths with mocked clients (no network). - Integration tests under `tests/integration_tests/test_embeddings.py`, gated on `PPLX_API_KEY` (matches the pattern in `test_search_api.py`). - README updated to advertise the new component. ### Why LangChain users already get chat, search, and tool wrappers from `langchain-perplexity`, but had to drop down to the raw Perplexity SDK to use embeddings. This closes that gap. ### References - Perplexity Embeddings docs: https://docs.perplexity.ai/docs/embeddings - Perplexity Embeddings API reference: https://docs.perplexity.ai/api-reference/embeddings-post ### Issue Closes #36726 ## Testing - `cd libs/partners/perplexity && make lint` — passes (ruff, format, mypy). - `cd libs/partners/perplexity && make test` — all unit tests pass (59 passed, 1 skipped). - Integration tests will run in CI with secrets; they exercise real `embed_documents` / `embed_query` / async variants against the live API and assert vector dimensionality consistency. --------- Co-authored-by: Claude Agent <agent@anthropic.com> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

chore(partners): standardize integration test invocation (#36958)
Standardize the `integration_tests` Makefile target across all 15 partner packages in `libs/partners/`, mirroring the deepagents `libs/evals` pattern (`-v --tb=short`). Previously each partner had its own ad-hoc flag stack (some missing `-n auto`, some with `-vvv`, others with nothing), and every partner that used `-n auto` was emitting a `PytestBenchmarkWarning` because `pytest-benchmark` is pulled in transitively via `langchain-tests` even though no partner has benchmark tests. |

chore(deps): bump pytest to 9.0.3 (#36801)
CVE-2025-71176 (medium severity) All are dev-only (test dependency group) — no impact on published packages. ### Why syrupy was also bumped syrupy 4.x (`<5.0.0`) constrains pytest to `<9.0.0`, blocking the CVE fix. Widening to `<6.0.0` allows syrupy 5.x which supports pytest 9.x. |

chore(partners): bump langchain-core min to 1.2.21 (#36183)
Bump the minimum `langchain-core` dependency to `>=1.2.21` across all 14 partner packages in the monorepo. Aligns partner lower bounds with the latest core release so consumers pick up recent fixes (notably the `ModelProfile` schema drift fix from core 1.2.21). |

fix(core,model-profiles): add missing ModelProfile fields, warn on schema drift (#36129)
PR #35788 added 7 new fields to the `langchain-profiles` CLI output (`name`, `status`, `release_date`, `last_updated`, `open_weights`, `attachment`, `temperature`) but didn't update `ModelProfile` in `langchain-core`. Partner packages like `langchain-aws` that set `extra="forbid"` on their Pydantic models hit `extra_forbidden` validation errors when Pydantic encountered undeclared TypedDict keys at construction time. This adds the missing fields, makes `ModelProfile` forward-compatible, provides a base-class hook so partners can stop duplicating model-profile validator boilerplate, migrates all in-repo partners to the new hook, and adds runtime + CI-time warnings for schema drift. ## Changes ### `langchain-core` - Add `__pydantic_config__ = ConfigDict(extra="allow")` to `ModelProfile` so unknown profile keys pass Pydantic validation even on models with `extra="forbid"` — forward-compatibility for when the CLI schema evolves ahead of core - Declare the 7 missing fields on `ModelProfile`: `name`, `status`, `release_date`, `last_updated`, `open_weights` (metadata) and `attachment`, `temperature` (capabilities) - Add `_warn_unknown_profile_keys()` in `model_profile.py` — emits a `UserWarning` when a profile dict contains keys not in `ModelProfile`, suggesting a core upgrade. Wrapped in a bare `except` so introspection failures never crash model construction - Add `BaseChatModel._resolve_model_profile()` hook that returns `None` by default. Partners can override this single method instead of redefining the full `_set_model_profile` validator — the base validator calls it automatically - Add `BaseChatModel._check_profile_keys` as a separate `model_validator` that calls `_warn_unknown_profile_keys`. Uses a distinct method name so partner overrides of `_set_model_profile` don't inadvertently suppress the check ### `langchain-profiles` CLI - Add `_warn_undeclared_profile_keys()` to the CLI (`cli.py`), called after merging augmentations in `refresh()` — warns at profile-generation time (not just runtime) when emitted keys aren't declared in `ModelProfile`. Gracefully skips if `langchain-core` isn't installed - Add guard test `test_model_data_to_profile_keys_subset_of_model_profile` in model-profiles — feeds a fully-populated model dict to `_model_data_to_profile()` and asserts every emitted key exists in `ModelProfile.__annotations__`. CI fails before any release if someone adds a CLI field without updating the TypedDict ### Partner packages - Migrate all 10 in-repo partners to the `_resolve_model_profile()` hook, replacing duplicated `@model_validator` / `_set_model_profile` overrides: anthropic, deepseek, fireworks, groq, huggingface, mistralai, openai (base + azure), openrouter, perplexity, xai - Anthropic retains custom logic (context-1m beta → `max_input_tokens` override); all others reduce to a one-liner - Add `pr_lint.yml` scope for the new `model-profiles` package |

ci: suppress pytest streaming output in CI (#36092)
Reduce CI log noise by suppressing pytest's per-test dot/verbose streaming output. The `_test.yml` workflow now passes `PYTEST_EXTRA=-q` to `make test`, which overrides the default verbosity with quiet mode — failures still print in full, but the thousands of `.......` progress lines are gone. Local `make test` is unaffected since `PYTEST_EXTRA` defaults empty. ## Changes - Add `PYTEST_EXTRA ?=` variable to all 21 package Makefiles and inject it into each `test` target's pytest invocation - Pass `PYTEST_EXTRA=-q` in `_test.yml` for both the main test step and the min-version retest step |

ci: avoid unnecessary dep installs in lint targets (#36046)
CI lint jobs use `uv run --all-groups` for all tools, but ruff doesn't need dependency resolution — only mypy does. By splitting into `UV_RUN_LINT` (ruff) and `UV_RUN_TYPE` (mypy), the CI-facing targets run ruff with `--group lint` only, giving fast-fail feedback before mypy triggers the full environment sync. For packages where source code only conditionally imports heavy deps (text-splitters, huggingface), `lint_package` also overrides `UV_RUN_TYPE` to `--group lint --group typing`, skipping the ~3.5GB `test_integration` download entirely. `lint_tests` keeps `--all-groups` since test code legitimately imports those deps. Additionally, `lint_imports.sh` was inconsistently wired — most packages had the script but weren't calling it. ## Changes **Makefile optimization** - Introduce `UV_RUN_LINT` and `UV_RUN_TYPE` Make variables, both defaulting to `uv run --all-groups`. For `lint_package` and `lint_tests`, `UV_RUN_LINT` is overridden to `uv run --group lint` so ruff runs instantly without syncing heavy deps - For `text-splitters` and `huggingface`, override `UV_RUN_TYPE` on `lint_package` to `uv run --group lint --group typing` — mypy runs without downloading torch, CUDA, spacy, etc. **mypy config for lean groups** - Add `transformers` and `transformers.*` to `ignore_missing_imports` in `text-splitters` pyproject.toml (conditional `try/except` import, same treatment as existing `konlpy`/`nltk` entries) - Add `torch`, `torch.*`, `langchain_community`, `langchain_community.*` to `ignore_missing_imports` in `huggingface` pyproject.toml - Add dual `# type: ignore[unreachable, unused-ignore]` in `text-splitters/base.py` to handle the `PreTrainedTokenizerBase` isinstance check that behaves differently depending on whether transformers is installed **lint_imports.sh consistency** - Add `./scripts/lint_imports.sh` to the lint recipe in every package that wasn't calling it (standard-tests, model-profiles, all 15 partners), and create the script for the two packages missing it entirely (`model-profiles`, `openrouter`) - Update all `lint_imports.sh` scripts to allow `from langchain.agents` and `from langchain.tools` imports (legitimate v1 middleware dependencies used by `langchain-anthropic` and `langchain-openai`) |

feat(model-profiles): new fields + Makefile target (#35788)
Extract additional fields from models.dev into `_model_data_to_profile`: `name`, `status`, `release_date`, `last_updated`, `open_weights`, `attachment`, `temperature` Move the model profile refresh logic from an inline bash script in the GitHub Actions workflow into a `make refresh-profiles` target in `libs/model-profiles/Makefile`. This makes it runnable locally with a single command and keeps the provider map in one place instead of duplicated between CI and developer docs. |

fix(model-profiles): sort generated profiles by model ID for stable diffs (#35344)
- Sort model profiles alphabetically by model ID (the top-level `_PROFILES` dictionary keys, e.g. `claude-3-5-haiku-20241022`, `gpt-4o-mini`) before writing `_profiles.py`, so that regenerating profiles only shows actual data changes in diffs — not random reordering from the models.dev API response order - Regenerate all 10 partner profile files with the new sorted ordering |
