fix(langchain): sanitize anthropic cache markers on fallback retries (#37867)
## Summary Fixes #33709. When `AnthropicPromptCachingMiddleware` runs before `ModelFallbackMiddleware`, Anthropic-specific `cache_control` markers can leak into fallback attempts targeting non-Anthropic models. This change makes fallback retries sanitize those markers only on non-primary attempts, preserving primary-call behavior and avoiding API changes. Related: langchain-ai/deepagentsjs#551. ## Changes ### libs/langchain_v1 - Added a private fallback sanitizer in `model_fallback.py` to remove Anthropic `cache_control` markers from fallback requests. - Sanitization covers `model_settings`, system/content message blocks, and tool payloads (`BaseTool.extras` plus dict-style tools/extras). - Applied sanitization in both sync and async fallback retry paths (`wrap_model_call` and `awrap_model_call`) while leaving the primary attempt unchanged. ### libs/langchain_v1 tests - Added sync and async regression tests in `test_model_fallback.py` that simulate primary failure and assert fallback calls only succeed when cache markers are stripped. - Verified non-cache settings (for example `temperature` and `top_p`) are preserved on fallback. - Preserved existing fallback behavior coverage (ordering, exhaustion, and error propagation). ## Compatibility with `BedrockPromptCachingMiddleware` The sanitizer also covers `BedrockPromptCachingMiddleware`, which injects `cache_control` into `model_settings` only. Bedrock-specific markers (`cachePoint` blocks, content-block `cache_control`) are applied by the chat model classes at API-call time and never appear in the `ModelRequest`, so no additional handling is needed. --------- Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com> |

fix(langchain): detect provider strategy for dated gpt-5.2/gpt-5.4 snapshots (#38222)
Closes #38220 --- Users calling `create_agent(..., response_format=<schema>)` with an OpenAI model pinned to a dated snapshot (e.g. `gpt-5.4-2026-03-05`) were silently downgraded from native structured output (`ProviderStrategy`) to tool-calling (`ToolStrategy`). This changes runtime behavior: extra tool-call traces, different token usage, and no provider-side schema enforcement. The cause is in `_supports_provider_strategy`'s fallback patterns: the `gpt-5.2` and `gpt-5.4` base patterns terminated with `($|[/:])`, which — unlike their sibling families — rejected a trailing `-`, so OpenAI's `-YYYY-MM-DD` dated-snapshot suffix matched none of the patterns. The base patterns were deliberately strict to keep `gpt-5.2-pro`/`gpt-5.4-pro` blocked, so rather than allowing any trailing `-` (which would re-admit those `-pro` variants) this change adds an optional dated-snapshot group `(-\d{4}-\d{2}-\d{2})?`. Dated snapshots now resolve to `ProviderStrategy` while `-pro` variants stay blocked.

chore: bump pyjwt from 2.12.0 to 2.13.0 in /libs/langchain_v1 (#38168)
Bumps [pyjwt](https://github.com/jpadilla/pyjwt) from 2.12.0 to 2.13.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/jpadilla/pyjwt/releases">pyjwt's releases</a>.</em></p> <blockquote> <h2>2.13.0</h2> <h1>PyJWT 2.13.0 — Security Release</h1> <p>This release bundles five security fixes plus three additional hardening / spec-compliance changes. We recommend all users upgrade.</p> <h2>Security</h2> <ul> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx"><code>GHSA-xgmm-8j9v-c9wx</code></a> — JWK JSON accepted as HMAC secret (algorithm confusion).</strong> <code>HMACAlgorithm.prepare_key</code> previously rejected PEM- and SSH-formatted asymmetric keys but did not catch a JWK passed as a raw JSON string. In a verifier configured with both symmetric and asymmetric algorithms in <code>algorithms=[…]</code> and a raw-JSON JWK as the key, an attacker could forge HS256 tokens using the JWK text as the HMAC secret. The guard has been extended to reject any JWK-shaped JSON. <em>Reported by <a href="https://github.com/aradona91"><code>@aradona91</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-jq35-7prp-9v3f"><code>GHSA-jq35-7prp-9v3f</code></a> — Algorithm allow-list bypass with <code>PyJWK</code> / <code>PyJWKClient</code>.</strong> When verifying with a <code>PyJWK</code>, the caller's <code>algorithms=[…]</code> allow-list was checked against the token header <code>alg</code> as a string only; actual verification used the algorithm bound to the <code>PyJWK</code>. An attacker who controlled a registered JWKS key could sign with one algorithm and advertise another on the header. PyJWT now requires the token header <code>alg</code> to match the <code>PyJWK</code>'s algorithm before verification. <em>Reported by <a href="https://github.com/sushi-gif"><code>@sushi-gif</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w7vc-732c-9m39"><code>GHSA-w7vc-732c-9m39</code></a> — DoS via base64 decode of unused payload segment when <code>b64=false</code>.</strong> For detached-payload JWS (<code>b64=false</code>), the compact-form payload segment was base64-decoded before being discarded in favor of the caller-supplied <code>detached_payload</code>. An attacker could inflate the unused segment to force CPU + memory cost without holding a valid signature. The segment is now required to be empty per RFC 7515 Appendix F, and is no longer decoded. <em>Reported by <a href="https://github.com/thesmartshadow"><code>@thesmartshadow</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-993g-76c3-p5m4"><code>GHSA-993g-76c3-p5m4</code></a> — <code>PyJWKClient</code> accepts non-HTTP(S) URIs.</strong> <code>PyJWKClient.fetch_data</code> passed its URI to <code>urllib.request.urlopen</code>, which by default also handles <code>file://</code>, <code>ftp://</code>, and <code>data:</code> schemes. An application that fed an attacker-influenced URI into <code>PyJWKClient</code> could be coerced into reading local files or reaching other unintended schemes. <code>PyJWKClient</code> now rejects any URI whose scheme isn't <code>http</code> or <code>https</code>. <em>Reported by <a href="https://github.com/KEIJOT"><code>@KEIJOT</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-fhv5-28vv-h8m8"><code>GHSA-fhv5-28vv-h8m8</code></a> — <code>PyJWKClient</code> cache wiped on fetch error.</strong> A <code>finally</code>-block <code>put(jwk_set=None)</code> cleared the JWK Set cache whenever a fetch raised, turning a transient JWKS-endpoint outage into application-wide auth failure. The cache write was moved into the success path; transient errors no longer evict valid cached keys. <em>Reported by <a href="https://github.com/eddieran"><code>@eddieran</code></a>.</em></p> </li> </ul> <h2>Fixed</h2> <ul> <li>Reject empty HMAC keys outright in <code>HMACAlgorithm.prepare_key</code> with <code>InvalidKeyError</code> instead of accepting them with only a warning. Defends against the <code>os.getenv("JWT_SECRET", "")</code> footgun. <em>Thanks to <a href="https://github.com/SnailSploit"><code>@SnailSploit</code></a> and <a href="https://github.com/spartan8806"><code>@spartan8806</code></a> for the reports.</em></li> <li>Forward per-call <code>options</code> (including <code>enforce_minimum_key_length</code>) from <code>PyJWT.decode</code> through to <code>PyJWS._verify_signature</code>. The option was previously silently dropped between the two layers, so it only took effect when set on the <code>PyJWT</code> instance. <em>Thanks to <a href="https://github.com/WLUB"><code>@WLUB</code></a> for the report.</em></li> <li><strong>RFC 7797 §3 compliance for <code>b64=false</code>:</strong> the encoder now auto-adds <code>"b64"</code> to <code>crit</code>, and the decoder rejects tokens that set <code>b64=false</code> without listing it in <code>crit</code>. <em>Thanks to <a href="https://github.com/MachineLearning-Nerd"><code>@MachineLearning-Nerd</code></a> for the report.</em></li> </ul> <h2>Changed</h2> <ul> <li>Migrate the <code>dev</code>, <code>docs</code>, and <code>tests</code> package extras to dependency groups, by <a href="https://github.com/kurtmckee"><code>@kurtmckee</code></a> in <a href="https://redirect.github.com/jpadilla/pyjwt/pull/1152">#1152</a>.</li> </ul> <h2>Upgrade notes</h2> <p>Most fixes are invisible to correctly-configured callers. A few behavioral changes you may encounter:</p> <ul> <li><strong>Empty HMAC keys now raise.</strong> If your app passed <code>""</code> or <code>b""</code> as a secret (often via a missing env var, e.g. <code>os.getenv("JWT_SECRET", "")</code>), <code>encode</code>/<code>decode</code> will now raise <code>InvalidKeyError</code>.

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. |

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(openai): support apply_patch built-in tool (#37157)
[Docs](https://github.com/langchain-ai/docs/pull/4370) Fixes #37031 Adds support for OpenAI Responses API `apply_patch` built-in tool. This PR: - Adds `apply_patch` to the OpenAI well-known tools list so `bind_tools([{"type": "apply_patch"}])` works. - Preserves `apply_patch_call` and `apply_patch_call_output` items when converting OpenAI Responses API outputs into LangChain `AIMessage.content`. - Preserves the same item types in streaming `AIMessageChunk` conversion. - Supports round-trip input conversion for `apply_patch_call` and `apply_patch_call_output`. - Adds unit tests for core tool passthrough, non-streaming conversion, streaming conversion, and round-trip input conversion. ## Testing - `cd libs/core && uv run --group test pytest tests/unit_tests/utils/test_function_calling.py -k "apply_patch" -vv` - `cd libs/partners/openai && uv run --group test pytest tests/unit_tests/chat_models/test_base.py -k "apply_patch" -vv` - `cd libs/core && uv run --all-groups ruff check langchain_core/utils/function_calling.py tests/unit_tests/utils/test_function_calling.py` - `cd libs/partners/openai && uv run --all-groups ruff check langchain_openai/chat_models/base.py tests/unit_tests/chat_models/test_base.py` --------- Co-authored-by: Mason Daugherty <github@mdrxy.com> Co-authored-by: Mason Daugherty <mason@langchain.dev> |

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). |

feat(langchain): redact streamed PII in flight on PIIMiddleware (#37616)
`PIIMiddleware` previously scrubbed detected PII only at the state level via its `after_model` / `before_model` hooks. Consumers reading the live stream — `astream_events(version="v3")` or `run.messages` / `run.tool_calls` / `run.values` — saw the raw model text, the raw tool-call args, the raw tool outputs, and the raw state snapshots until the run finished and the canonical conversation history was written. This change registers a stream transformer ahead of `MessagesTransformer` that redacts every wire surface of an agent run. The transformer holds a sliding lookback buffer (default 128 characters) per `(run_id, content-block index)` so PII patterns that straddle delta boundaries are caught before the safe prefix is released downstream. Anything older than the lookback is run through the configured detector and emitted; the trailing tail stays buffered until a later delta extends it past the cap or the block finishes. `_finalize_block` always re-runs detection over the full block snapshot so the finalized content lands fully redacted even when the in-flight buffer never released a tail (short responses, or PII arriving in the final delta). The `block` strategy is now supported on the streaming path via a buffering mode that withholds every delta until the block resolves — clean blocks release the full text at finalize, PII-bearing blocks zero the wire and let `after_model` / `apply_to_tool_results` raise `PIIDetectionError` on the original state message. Activation is gated on `apply_to_output=True`, matching the existing post-hoc semantics. The middleware's transformer factory is cloned by `StreamMux._make_child` into every subgraph scope, so attaching `PIIMiddleware` at the outer agent also redacts streamed deltas from sub-agents invoked inside tools. ## Tool-call and tools-channel coverage The transformer covers every wire surface of an agent run, not just AI message text: - **Streamed AI text deltas** (`content-block-delta` of type `text-delta`) — lookback machinery, redacted in place. - **Streamed tool-call args** (`content-block-delta` with `tool_call_chunk` / `server_tool_call_chunk` fields) — each delta carries the full cumulative args string; detection runs on the field directly and redacts in place. Verified empirically against `_compat_bridge.py` and the consumer-side `_merge_block_delta_into_store` snapshot-replace semantics. - **Finalized tool-call blocks** (`content-block-finish` with `tool_call` / `server_tool_call` / `invalid_tool_call`) — `args` dict walked recursively and each string leaf redacted. - **Tool execution events on the `tools` channel** — `tool-started.input`, `tool-output-delta`, `tool-finished.output`, `tool-error.message` all run through detection. String deltas use the same lookback machinery as text-deltas keyed by `tool_call_id`; structured payloads walk recursively. - **State snapshots on the `values` channel** — message lists are walked and each message's `.content` is redacted on a fresh copy. Graph state itself stays intact for the state-level enforcer (`apply_to_tool_results` via `before_model`) to act on independently. - **Legacy `(BaseMessage, metadata)` payloads** on the `messages` channel (Python 3.10 path, where `langgraph`'s `ASYNCIO_ACCEPTS_CONTEXT = sys.version_info >= (3, 11)` falls back to a code path that doesn't propagate the streaming callback into the chat model) — `.content` and `AIMessage.tool_calls[*].args` are scrubbed. For `block`, the event's `data` tuple is replaced with an empty-content copy so the original message stays in state for `after_model` to raise on. ## Worth a careful look - `_PIIStreamTransformer._mutate_text_delta` — lookback partition. Anything older than `lookback` characters is released after redaction; the tail stays buffered. Bulletproof against whitespace-permissive detectors (notably `credit_card`, whose regex matches across spaces). - `_PIIStreamTransformer._mutate_tool_call_chunk_delta` — direct in-place redaction of the cumulative args string. No buffer; the wire shape is cumulative-snapshot, the consumer-side merge is replace-not-append. - `_PIIStreamTransformer._mutate_legacy_payload` — the dual path: mutate-in-place for non-`block` (idempotent with `after_model`), replace-with-empty-copy for `block` (keeps original in graph state for `after_model` to raise on). - `_PIIStreamTransformer._redact_value` — the recursive walker. `BaseMessage` branch returns a fresh `.content`-redacted copy via `model_copy(update=...)` — never mutates in place — so tool-output payloads that wrap a `ToolMessage` and message lists in state snapshots flow through cleanly. - The new `transformers` attribute on `PIIMiddleware`: this is what makes `create_agent` pick the factory up. Multiple `PIIMiddleware` instances each register one transformer; ordering is preserved within the `before_builtins` lane. ## Compatibility Bumps `langgraph` to `>=1.2.1` for the `before_builtins` opt-in on `StreamTransformer`. |

chore(langchain-classic): deprecate hub, limit loads/dumps (#37234)
deprecate hub classic and hub runnable. This code path isn't expected to be active for most users (it's dependent on having a very old version of the langsmith sdk). harden usage of loads/dumps. |

chore(langchain,langchain-classic): uncomment optional deps (#37163)
Re-enable the `[community]`, `[azure-ai]`, and `[cohere]` extras on `langchain-classic`, and the `[cohere]` extra on `langchain` (v1). These had been commented out as a temporary workaround during the `langchain` -> `langchain-classic` rename so the renamed package could ship before downstream partners were re-released against it. Now that `langchain-community` 0.4.1, `langchain-cohere` 0.5.1, and `langchain-azure-ai` 1.2.3 are published with the correct dependency targets, the extras can be restored. |
