fix(anthropic): ignore LangSmith requests in VCR cassettes (#38547)
Anthropic integration tests can run with LangSmith tracing enabled in scheduled CI, which sends LangSmith API requests while VCR cassettes are active. Ignore LangSmith ingest endpoints in the Anthropic VCR config so cassette playback only matches Anthropic traffic. ## Changes - Add `api.smith.langchain.com` to the Anthropic VCR `ignore_hosts` configuration while preserving any hosts from the shared base config. - Keep existing Anthropic cassette serialization, request redaction, and response redaction behavior unchanged. |

fix(anthropic): keep initial text on content_block_start (#38442)
## Summary - Fix `ChatAnthropic._make_message_chunk_from_anthropic_event` dropping the first text chunk of an assistant turn when Anthropic carries the opening text on the `content_block_start` event rather than a following `text_delta`. This most often hits the assistant turn right after a tool result. - The dropped content streams to clients but never reaches the aggregated `AIMessage`, so anything reading message history back (e.g. a checkpointer) sees a truncated message (`Here's the answer.` → `'s the answer.`). Reported via Pylon 25478 (Zip), whose `<canvaspreview>` parser broke because the dropped chunk was the opening `<can` tag. - Add a `content_block_start` branch for `text` and `thinking` blocks: emit non-empty start-event content on both the string (`coerce_content_to_string=True`) and structured content paths; empty starts still emit no chunk (preserving prior behavior) and update `block_start_event` so following deltas resolve against the current block. --------- Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

fix(core): add messages to bare raise ValueError calls (#38158)
Closes #35727 --- Several internal code paths raised a bare `ValueError` with no message, so when one of these conditions tripped, users saw a traceback with no explanation of what actually went wrong. This adds descriptive messages to each of those `raise ValueError` calls: - `FewShotPromptWithTemplates._get_examples` / `_aget_examples` — when neither `examples` nor `example_selector` is set. - Prompt `loading` — when a referenced template file uses an unsupported (non-`.txt`) format. - The LangSmith document loader — when both `client` and `client_kwargs` are supplied. - The Anthropic file-search middleware brace expansion — for unbalanced or empty brace patterns.

chore: bump vcrpy from 8.1.1 to 8.2.1 in /libs/partners/anthropic (#38324)
Bumps [vcrpy](https://github.com/kevin1024/vcrpy) from 8.1.1 to 8.2.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/kevin1024/vcrpy/releases">vcrpy's releases</a>.</em></p> <blockquote> <h2>v8.2.1</h2> <h2>What's Changed</h2> <ul> <li><strong>SECURITY:</strong> Cassettes are now loaded with a safe YAML loader, preventing arbitrary code execution when a cassette from an untrusted source is loaded. Previously a crafted cassette containing a Python object tag (e.g. <code>!!python/object/apply:os.system</code>) would execute code on load, including via the normal <code>vcr.use_cassette()</code> path. Existing cassettes (including file-upload/streaming bodies) continue to load.

docs(anthropic): clarify prompt caching middleware docstring (#38206)
Updates the `AnthropicPromptCachingMiddleware` class docstring so it no longer implies the middleware itself tags the final message tail. It tags the system message and tool definitions and passes `cache_control` via `model_settings`; the chat model/provider applies the message-tail and provider-specific behavior. Docstring-only, no runtime change. Made by [Open SWE](https://openswe.vercel.app/agents/27913c08-b40c-015e-afee-cf66788b7f08) --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> |

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. |

test(core,langchain): update tests for explicit deserialization allowlists (#38118)
Core serialization tests now opt into the object allowlists they rely on instead of assuming default deserialization permits core objects. Compatibility tests that intentionally exercise deprecated runnable streaming and history APIs also suppress the expected deprecation warnings so they can keep covering those legacy paths cleanly. ## Changes - Updated serialization and prompt round-trip tests to pass `allowed_objects="core"` or targeted allowlists when loading `AIMessage`, prompt templates, structured prompts, runnable maps, and related core objects. - Adjusted secret-injection regression coverage to keep testing `secrets_from_env=True` behavior while explicitly allowing core deserialization paths. - Tightened prompt deserialization rejection tests so attribute-access payloads are loaded only through the specific prompt-template allowlist needed to reach validation. - Added module-level warning filters around legacy runnable compatibility coverage for `astream_log`, `astream_events(version="v1")`, and `RunnableWithMessageHistory`. - Bumped the `langchain` package's minimum `langgraph` dependency from `1.2.4` to `1.2.5`. ## Testing - Updated unit tests across core serialization, prompt, fake chat model, runnable history, and runnable event coverage. |

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. |

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. |

test(anthropic): make expected warnings explicit (#38044)

fix(core): support content block tokens in callbacks (#34739)
Supersedes #34727 Closes #30703 Related: * langchain-ai/langchain-google#1460 * langchain-ai/langchain-google#1501 Fixing this at the `langchain-core` callback layer instead of normalizing inside individual provider integrations, so structured streaming content is preserved consistently. --- Models are increasingly streaming structured content blocks instead of plain text tokens. For example, Gemini 3 can stream text as content-block lists, and Anthropic/tool-use flows can also produce non-text message content. Today those values already reach `on_llm_new_token`, but the callback API still advertises `token: str`, which makes custom callbacks, tracers, and streaming helpers assume every streamed value is text. User story: as a LangChain user building a streaming callback for chat models with tool calls, reasoning/thinking blocks, or provider-specific structured content, I need `on_llm_new_token` to accept the same content shape that chat model chunks can actually emit, so my callback can observe the stream without providers flattening or dropping non-text data. Fixing this in `langchain-core` makes the existing runtime behavior explicit at the shared callback boundary. Normalizing content blocks inside each provider would duplicate logic, produce inconsistent behavior across integrations, and in some cases lose required provider metadata such as Gemini thought signatures. ## Changes - Update the callback contract so streamed tokens can be either plain text or structured content blocks - Carry structured streamed content through tracing and event/log streaming paths without forcing provider data into text too early - Keep built-in text-oriented streaming callbacks working by converting structured tokens only at the display/queue boundary - Drop the now-incorrect `cast("str", ...)` on streamed content in `BaseChatModel` so the producer side matches the widened callback signature instead of asserting a string it doesn't always have (no runtime change — `cast` is erased) - Align Anthropic and Mistral content typing with the structured content shapes already used by chat model messages - Update callback tests to reflect that not every streamed value is text ## Compatibility No runtime behavior change: no producer emits anything it wasn't already emitting, and widening a parameter type is safe for existing callers and handlers that pass or receive `str`. The one caveat is downstream code that subclasses a callback handler or tracer and overrides `on_llm_new_token` with a `token: str` annotation — under strict type checking that override is now narrower than the base and will be flagged as incompatible with the supertype. Such code still runs unchanged; the fix is to widen the annotation to match. |

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. |

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. |

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. |

Sweep classic deprecations so every removal lands on `2.0.0`, runtime warnings carry the auto-generated since/removal/alternative line, and replacements steer at `langchain.agents.create_agent` and `with_structured_output(...)` instead of pre-v1 LangGraph + `python.langchain.com` links. ## Changes - **Bump removal targets from `1.0` / `1.0.0` to `2.0.0`** across agents, chains, memory, retrievers, structured-output, vectorstore toolkits, and the `langchain_classic._api.module_import` shim — gives users a real runway now that v1 has shipped. - **Move bespoke `message=` strings onto `addendum=`** (or split into `alternative=` + `addendum=`). `warn_deprecated` skips the auto-generated since/removal/alternative line whenever `message=` is set, so the prior pattern silently dropped that info from the runtime `LangChainDeprecationWarning`. Matches the pattern already used in `HTMLHeaderTextSplitter.split_text_from_url`, which is updated for consistency. - **Repoint `alternative=` at v1 replacements**: chains/memory/agent toolkits → `langchain.agents.create_agent` (with checkpointer or retrieval-tool guidance in the addendum); `openai_functions` and `chains/structured_output` → `ChatModel.with_structured_output(...)`; `openapi` chains → `ChatModel.bind_tools(...)` + HTTP client. `ConversationChain` no longer points at `RunnableWithMessageHistory`. - **Refresh `AGENT_DEPRECATION_WARNING`** in `langchain_classic._api.deprecation` — drop stale LangGraph and `python.langchain.com` links in favor of `langchain.agents.create_agent` and the `docs.langchain.com/oss/python/migrate/langchain-v1` guide. Propagates to all 13 caller sites in `agents/`. - **Newly deprecate `langchain_classic.chat_models.init_chat_model` and `langchain_classic.embeddings.init_embeddings`** with the framing *"maintained in `langchain`; `langchain-classic` retains this entry point for import-compatibility only"*. The classic docstring examples and the warning admonition both point at `langchain.chat_models`. - **Improve `init_chat_model` docstrings** in both `langchain_v1` and the classic copy: clarify `provider:model` prefix vs. `model_provider=`, recommend pinned IDs over moving aliases, add the `upstage` provider row, and refresh examples to GA models (`gpt-5.5`, `claude-opus-4-7`). - **Standardize partner Anthropic deprecations**: replace `AnthropicLLM`'s `model_validator(raise_warning)` with `@deprecated(since="0.1.0", removal="2.0.0", alternative="ChatAnthropic")`, and pin the `ChatAnthropic` `output_format` runtime warning at `langchain-anthropic 2.0.0` instead of "a future version". |
