James Espichan Vilca	080741d336	core[patch]: Fix type for inner input in base prompts (#25713 ) Thank you for contributing to LangChain! - [ ] PR title: "langchain-core: Fix type" - The file to modify is located in /libs/core/langchain_core/prompts/base.py - [ ] PR message: - Description: The change is a type for the inner input variable, the type go from dict to Any. This change is required since the method _validate input expects a type that is not only a dictionary. - Dependencies: There are no dependencies for this change - [ ] Add tests and docs: 1. A test is not needed. This error occurs because I overrode a portion of the _validate_input method, which is causing a 'beartype' to raise an error.	1 month 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.

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. Issue: No corresponding issues. Dependencies: No dependencies required.
