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	3 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. For example: - libs/core/langchain_core/messages/__init__.py : AnyMessage, MessageLikeRepresentation, get_buffer_string(), messages_from_dict(), ... 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`(???)

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>	3 months ago

Anthony Shaw	bb0dd8f82f	docs: Embellish article on splitting by tokens with more examples and missing details (#18997 ) Description This PR adds some missing details from the "Split by tokens" page in the documentation. Specifically: - The `.from_tiktoken_encoder()` class methods for both the `CharacterTextSplitter` and `RecursiveCharacterTextSplitter` default to the old `gpt-2` encoding. I've added a comment to suggest specifying `model_name` or `encoding` - The docs didn't mention that the `from_tiktoken_encoder()` class method passes additional kwargs down to the constructor of the splitter. I only discovered this by reading the source code - Added an example of using the `.from_tiktoken_encoder()` class method with `RecursiveCharacterTextSplitter` which is the recommended approach for most scenarios above `CharacterTextSplitter` - Added a warning that `TokenTextSplitter` can split characters which have multiple tokens (e.g. 猫 has 3 cl100k_base tokens) between multiple chunks which creates malformed Unicode strings and should not be used in these situations. Side note: I think the default argument of `gpt2` for `.from_tiktoken_encoder()` should be updated?

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.
