Ian	64ace25eb8	<Community>: tidb vector support vector index (#19984 ) This PR introduces adjustments to ensure compatibility with the recently released preview version of [TiDB Serverless Vector Search](https://tidb.cloud/ai), aiming to prevent user confusion. - TiDB Vector now supports vector indexing with cosine and l2 distance strategies, although inner_product remains unsupported. - Changing the distance strategy is currently not supported, so the test cased should be adjusted.	4 weeks ago
Austin Burdette	f355a98bb6	community:yuan2[patch]: standardize init args (#21462 ) updated stop and request_timeout so they aliased to stop_sequences, and timeout respectively.

James Espichan Vilca	644e0d3463	Use extend method for embeddings concatenation in mlflow_gateway (#14358 ) ## Description There is a bug in the concatenation of embeddings obtained from MLflow that does not conform to the type hint requested by the function. ``` python def _query(self, texts: List[str]) -> List[List[float]]: ``` It is logical to expect a List[List[float]] for a List[str]. However, the append method encapsulates the response in a global List. To avoid this, the extend method should be used, which will add the embeddings of all strings at the same list level. ## Testing I have tried using OpenAI-ADA to obtain the embeddings, and the result of executing this snippet is as follows: ``` python embeds = await MlflowAIGatewayEmbeddings().aembed_documents(texts=["hi", "how are you?"]) print(embeds) ``` ``` python [[[-0.03512698, -0.020624293, -0.015343423, ...], [-0.021260535, -0.011461929, -0.00033121882, ...]]] ``` When in reality, the expected result should be: ``` python [[-0.03512698, -0.020624293, -0.015343423, ...], [-0.021260535, -0.011461929, -0.00033121882, ...]] ``` The above result complies with the expected type hint: List[List[float]] . As I mentioned, we can achieve that by using the extend method instead of the append method. --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: ccurme <chester.curme@gmail.com>	4 weeks ago

Yusuke Fukasawa	0258cb96fa	core[patch]: add additionalProperties recursively to oai function if strict (#25169 ) Hello. First of all, thank you for maintaining such a great project. ## Description In https://github.com/langchain-ai/langchain/pull/25123, support for structured_output is added. However, `"additionalProperties": false` needs to be included at all levels when a nested object is generated. error from current code: https://gist.github.com/fufufukakaka/e9b475300e6934853d119428e390f204 ``` BadRequestError: Error code: 400 - {'error': {'message': "Invalid schema for response_format 'JokeWithEvaluation': In context=('properties', 'self_evaluation'), 'additionalProperties' is required to be supplied and to be false", 'type': 'invalid_request_error', 'param': 'response_format', 'code': None}} ``` Reference: [Introducing Structured Outputs in the API](https://openai.com/index/introducing-structured-outputs-in-the-api/) ```json { "model": "gpt-4o-2024-08-06", "messages": [ { "role": "system", "content": "You are a helpful math tutor." }, { "role": "user", "content": "solve 8x + 31 = 2" } ], "response_format": { "type": "json_schema", "json_schema": { "name": "math_response", "strict": true, "schema": { "type": "object", "properties": { "steps": { "type": "array", "items": { "type": "object", "properties": { "explanation": { "type": "string" }, "output": { "type": "string" } }, "required": ["explanation", "output"], "additionalProperties": false } }, "final_answer": { "type": "string" } }, "required": ["steps", "final_answer"], "additionalProperties": false } } } } ``` In the current code, `"additionalProperties": false` is only added at the last level. This PR introduces the `_add_additional_properties_key` function, which recursively adds `"additionalProperties": false` to the entire JSON schema for the request.

Currently, the `file_extension` argument of `GithubFileLoader` does not change its behavior at all. 1. The `GithubFileLoader` sample code in `docs/docs/integrations/document_loaders/github.ipynb` does not work as it stands. The respective solutions I propose are the following: 1. Remove `file_extension` argument from `GithubFileLoader`. 1.

CastaChick	7d13a2f958	core[patch]: add option to specify the chunk separator in `merge_message_runs` (#24783 ) Description: LLM will stop generating text even in the middle of a sentence if `finish_reason` is `length` (for OpenAI) or `stop_reason` is `max_tokens` (for Anthropic). To obtain longer outputs from LLM, we should call the message generation API multiple times and merge the results into the text to circumvent the API's output token limit. The extra line breaks forced by the `merge_message_runs` function when seamlessly merging messages can be annoying, so I added the option to specify the chunk separator.
