Noah Stapp	34e6f3ff72	community[patch]: Implement similarity_score_threshold for MongoDB Vector Store (#14740) ... Adds the option for `similarity_score_threshold` when using `MongoDBAtlasVectorSearch` as a vector store retriever. Example use: ``` vector_search = MongoDBAtlasVectorSearch.from_documents(...) qa_retriever = vector_search.as_retriever( search_type="similarity_score_threshold", search_kwargs={ "score_threshold": 0.5, } ) qa = RetrievalQA.from_chain_type( llm=OpenAI(), chain_type="stuff", retriever=qa_retriever, ) docs = qa({"query": "..."}) ``` I've tested this feature locally, using a MongoDB Atlas Cluster with a vector search index.	7 months ago

William FH	c5296fd42c	[Documentation] Updates to NVIDIA Playground/Foundation Model naming.… (#14770) ... … (#14723) - **Description:** Minor updates per marketing requests. Namely, name decisions (AI Foundation Models / AI Playground) - **Tag maintainer:** @hinthornw Do want to pass around the PR for a bit and ask a few more marketing questions before merge, but just want to make sure I'm not working in a vacuum. No major changes to code functionality intended; the PR should be for documentation and only minor tweaks. Note: QA model is a bit borked across staging/prod right now. Relevant teams have been informed and are looking into it, and I'm placeholdered the response to that of a working version in the notebook.

葛尧	e780433f6b	Fix token_usage None issue in ChatOpenAI with local Chatglm2-6B (#14493) ... When using local Chatglm2-6B by changing OPENAI_BASE_URL to localhost, the token_usage in ChatOpenAI becomes None. This leads to an AttributeError when trying to access token_usage.items(). This commit adds a check to ensure token_usage is not None before accessing its items. This change prevents the AttributeError and allows ChatOpenAI to work seamlessly with a local Chatglm2-6B model, aligning with the way it operates with the OpenAI API. <!-- Thank you for contributing to LangChain!

Thomas B	b4e3e47c92	feat: Yaml output parser (#14496) ... ## Description New YAML output parser as a drop-in replacement for the Pydantic output parser. Yaml is a much more token-efficient format than JSON, proving to be **~35% faster and using the same percentage fewer completion tokens**. ☑️ Formatted ☑️ Linted ☑️ Tested (analogous to the existing`test_pydantic_parser.py`) The YAML parser excels in situations where a list of objects is required, where the root object needs no key: ```python class Products(BaseModel): __root__: list[Product] ``` I ran the prompt `Generate 10 healthy, organic products` 10 times on one chain using the `PydanticOutputParser`, the other one using the`YamlOutputParser` with `Products` (see below) being the targeted model to be created. LLMs used were Fireworks' `lama-v2-34b-code-instruct` and OpenAI `gpt-3.5-turbo`. All runs succeeded without validation errors. ```python class Nutrition(BaseModel): sugar: int = Field(description="Sugar in grams") fat: float = Field(description="% of daily fat intake") class Product(BaseModel): name: str = Field(description="Product name") stats: Nutrition class Products(BaseModel): """A list of products""" products: list[Product] # Used `__root__` for the yaml chain ``` Stats after 10 runs reach were as follows: ### JSON ø time: 7.75s ø tokens: 380.8 ### YAML ø time: 5.12s ø tokens: 242.2 Looking forward to feedback, tips and contributions!	7 months ago
