Luca Dorigo	f19229c564	core[patch]: fix beta, deprecated typing (#18877 ) Description: While not technically incorrect, the TypeVar used for the `@beta` decorator prevented pyright (and thus most vscode users) from correctly seeing the types of functions/classes decorated with `@beta`. This is in part due to a small bug in pyright (https://github.com/microsoft/pyright/issues/7448 ) - however, the `Type` bound in the typevar `C = TypeVar("C", Type, Callable)` is not doing anything - classes are `Callables` by default, so by my understanding binding to `Type` does not actually provide any more safety - the modified annotation still works correctly for both functions, properties, and classes. --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	2 months ago

Nuno Campos	fdfb51ad8d	core: Two updates to chat model interface (#19684 ) - .stream() and .astream() call on_llm_new_token, removing the need for subclasses to do so. Backwards compatible because now we don't pass run_manager into ._stream and ._astream - .generate() and .agenerate() now handle `stream: bool` kwarg for _generate and _agenerate. Subclasses handle this arg by delegating to ._stream(), now one less thing they need to do. Backwards compat because this is an optional arg that we now never pass to the subclasses - .generate() and .agenerate() now inspect callback handlers to decide on a default value for stream:bool if not passed in. This auto enables streaming when using astream_events and astream_log - as a result of these three changes any usage of .astream_events and .astream_log should now yield chat model stream events - In future PRs we can update all subclasses to reflect these two things now handled by base class, but in meantime all will continue to work	2 months ago

This PR adds a separate `PydanticV2OutputParser`, as well as a `langchain_core.pydantic_v2` namespace that will fail on import to any projects using pydantic<2. Happy to update the docs for output parsers if this is something we're interesting in adding.

William FH	68298cdc82	[Feat] Accept non-dict if only 1 prompt input variable (#19156 ) For prompt templates with only 1 variable (common in e.g., MessageGraph), it's convenient to wrap the incoming object in the variable before formatting. The downside of this, of course, would be that some number of invocations will successfully format when the user may have intended to format it properly before	2 months ago

Leonid Ganeline	8609afbd10	core[patch]: Update `messages` namespace to fix API reference docs (#19161 ) Classes and functions defined in __init__.py are not parsed into the API Reference.

Opinionated: __init__.py is not a typical place to define artifacts. Moved artifacts from __init__ into utils.py. Added `MessageLikeRepresentation` to __all__ since it is used outside of `messages`, for example, in `libs/core/langchain_core/language_models/base.py` Added `_message_from_dict` to __all__ since it is used outside of `messages`(???) I would add `message_from_dict` (without underscore) as an alias. Please, advise.	2 months ago
Christophe Bornet	4c2e887276	core: Simplify astream logic in BaseChatModel and BaseLLM (#19332 ) Covered by tests in `libs/core/tests/unit_tests/language_models/chat_models/test_base.py`, `libs/core/tests/unit_tests/language_models/llms/test_base.py` and `libs/core/tests/unit_tests/runnables/test_runnable_events.py`	2 months ago
Chris Papademetrious	305d74c67a	core: implement a batch_size parameter for CacheBackedEmbeddings (#18070 ) Description: Currently, `CacheBackedEmbeddings` computes vectors for all uncached documents before updating the store. This pull request updates the embedding computation loop to compute embeddings in batches, updating the store after each batch. I noticed this when I tried `CacheBackedEmbeddings` on our 30k document set and the cache directory hadn't appeared on disk after 30 minutes. The motivation is to minimize compute/data loss when problems occur: * If there is a transient embedding failure (e.g. a network outage at the embedding endpoint triggers an exception), at least the completed vectors are written to the store instead of being discarded. * If there is an issue with the store (e.g. no write permissions), the condition is detected early without computing (and discarding!) all the vectors. Issue: Implements enhancement #18026. Testing: I was unable to run unit tests; details in [this post](https://github.com/langchain-ai/langchain/discussions/15019#discussioncomment-8576684). --------- Signed-off-by: chrispy <chrispy@synopsys.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	2 months ago

Roshan Santhosh	7afecec280	core: update _rm_titles to account for title argument name bug (#19036 ) Issue : For functions which have an argument with the name 'title', the convert_pydantic_to_openai_function generates an incorrect output and omits the argument all together. This is because the _rm_titles function removes all instances of the the key 'title' from the output. Description : Updates the _rm_titles function to check the presence of the 'type' key as well before removing the 'title' key. As the title key that we wish to omit always has a type key along with it. Potential gap if there is a function defined which has both title and key as argument names, in which case this would fail. Maybe we could set a filter on the function argument names and reject those with keyword argument names. No dependencies.

William FH	780337488e	[Enhancement] Add support for directly providing a run_id (#18990 ) The root run id (~trace id's) is useful for assigning feedback, but the current recommended approach is to use callbacks to retrieve it, which has some drawbacks: 1. Doesn't work for streaming until after the first event 2. Doesn't let you call other endpoints with the same trace ID in parallel (since you have to wait until the call is completed/started to use This PR lets you provide = "run_id" in the runnable config. Couple considerations: 1. For batch calls, we split the trace up into separate trees (to permit better rendering). We keep the provided run ID for the first one and generate a unique one for other elements of the batch. 2. For nested calls, the provided ID is ONLY used on the top root/trace. ### Example Usage ``` chain.invoke("foo", {"run_id": uuid.uuid4()}) ```	2 months ago

ccurme	1b0802babe	core: fix .bind when used with RunnableLambda async methods (#17739 ) Description: Here is a minimal example to illustrate behavior: ```python from langchain_core.runnables import RunnableLambda def my_function(args, kwargs): return 3 + kwargs.get("n", 0) runnable = RunnableLambda(my_function).bind(n=1) assert 4 == runnable.invoke({}) assert [4] == list(runnable.stream({})) assert 4 == await runnable.ainvoke({}) assert [4] == [item async for item in runnable.astream({})] ``` Here, `runnable.invoke({})` and `runnable.stream({})` work fine, but `runnable.ainvoke({})` raises ``` TypeError: RunnableLambda._ainvoke.<locals>.func() got an unexpected keyword argument 'n' ``` and similarly for `runnable.astream({})`: ``` TypeError: RunnableLambda._atransform.<locals>.func() got an unexpected keyword argument 'n' ``` Here we assume that this behavior is undesired and attempt to fix it.
