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.

Eugene Yurtsev	6dd9f053e3	core[patch]: Deprecating beta upsert APIs in vectorstore (#25069 ) This PR deprecates the beta upsert APIs in vectorstore. We'll introduce them in a V2 abstraction instead to keep the existing vectorstore implementations lighter weight. The main problem with the existing APIs is that it's a bit more challenging to implement the correct behavior w/ respect to IDs since ID can be present in both the function signature and as an optional attribute on the document object. But VectorStores that pass the standard tests should have implemented the semantics properly! --------- Co-authored-by: Erick Friis <erick@langchain.dev>	2 months ago

blueoom	c3ced4c6ce	core[patch]: use time.monotonic() instead time.time() in InMemoryRateLimiter Description: The get time point method in the _consume() method of core.rate_limiters.InMemoryRateLimiter uses time.time(), which can be affected by system time backwards. Therefore, it is recommended to use the monotonically increasing monotonic() to obtain the time ```python with self._consume_lock: now = time.time() # time.time() -> time.monotonic() # initialize on first call to avoid a burst if self.last is None: self.last = now elapsed = now - self.last # when use time.time(), elapsed may be negative when system time backwards ```	2 months ago
