Jiejun Tan	2be66a38d8	huggingface: Fix huggingface tei support (#22653 ) Update former pull request: https://github.com/langchain-ai/langchain/pull/22595. Modified `libs/partners/huggingface/langchain_huggingface/embeddings/huggingface_endpoint.py`, where the API call function does not match current [Text Embeddings Inference API](https://huggingface.github.io/text-embeddings-inference/#/Text%20Embeddings%20Inference/embed). One example is: ```json { "inputs": "string", "normalize": true, "truncate": false } ``` Parameters in `_model_kwargs` are not passed properly in the latest version. By the way, the issue [why cause 413? #50](https://github.com/huggingface/text-embeddings-inference/issues/50) might be solved.	3 months ago
Eugene Yurtsev	9ccc4b1616	core[patch]: Fix logic in BaseChatModel that processes the llm string that is used as a key for caching chat models responses (#23842 ) This PR should fix the following issue: https://github.com/langchain-ai/langchain/issues/23824 Introduced as part of this PR: https://github.com/langchain-ai/langchain/pull/23416 I am unable to reproduce the issue locally though it's clear that we're getting a `serialized` object which is not a dictionary somehow. The test below passes for me prior to the PR as well ```python def test_cache_with_sqllite() -> None: from langchain_community.cache import SQLiteCache from langchain_core.globals import set_llm_cache cache = SQLiteCache(database_path=".langchain.db") set_llm_cache(cache) chat_model = FakeListChatModel(responses=["hello", "goodbye"], cache=True) assert chat_model.invoke("How are you?").content == "hello" assert chat_model.invoke("How are you?").content == "hello" ```	3 months ago

kiarina	dc396835ed	langchain_anthropic: add stop_reason in ChatAnthropic stream result (#23689 ) `ChatAnthropic` can get `stop_reason` from the resulting `AIMessage` in `invoke` and `ainvoke`, but not in `stream` and `astream`. This is a different behavior from `ChatOpenAI`. It is possible to get `stop_reason` from `stream` as well, since it is needed to determine the next action after the LLM call. This would be easier to handle in situations where only `stop_reason` is needed. - Issue: NA - Dependencies: NA - Twitter handle: https://x.com/kiarina37	3 months ago

SN	acc457f645	core[patch]: fix nested sections for mustache templating (#23747 ) The prompt template variable detection only worked for singly-nested sections because we just kept track of whether we were in a section and then set that to false as soon as we encountered an end block. i.e. the following: ``` {{#outerSection}} {{variableThatShouldntShowUp}} {{#nestedSection}} {{nestedVal}} {{/nestedSection}} {{anotherVariableThatShouldntShowUp}} {{/outerSection}} ``` Would yield `['outerSection', 'anotherVariableThatShouldntShowUp']` as input_variables (whereas it should just yield `['outerSection']`). This fixes that by keeping track of the current depth and using a stack.	3 months ago
