Eugene Yurtsev	cdfb5b4ca1	core[minor]: Chat Models to fallback astream to fallback on sync stream if available (#18748) ... Allows all chat models that implement _stream, but not _astream to still have async streaming to work. Amongst other things this should resolve issues with streaming community model implementations through langserve since langserve is exclusively async.	6 months ago

Jan Nissen	b8922480ed	core[patch]: improve PydanticOutputParser typing (#18740) ... This PR adds generic typing to `PydanticOutputParser` so we get a typed output from `.parse` instead of `Any`. It should provide a better DX by way of Intellisense and for anyone strictly typing. Pre-change:  Post-change:  I haven't dug too deep, but I think a similar change could probably be added to `JsonOutputParser` so we don't have to pull up `.parse`.

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. **Issue:** https://github.com/langchain-ai/langchain/issues/17241, https://github.com/langchain-ai/langchain/discussions/16446	7 months ago
