Moritz Schlager	555f97becb	community[patch]: fix model initialization bug for deepinfra (#25727) ... ### Description adds an init method to ChatDeepInfra to set the model_name attribute accordings to the argument ### Issue currently, the model_name specified by the user during initialization of the ChatDeepInfra class is never set. Therefore, it always chooses the default model (meta-llama/Llama-2-70b-chat-hf, however probably since this is deprecated it always uses meta-llama/Llama-3-70b-Instruct). We stumbled across this issue and fixed it as proposed in this pull request. Feel free to change the fix according to your coding guidelines and style, this is just a proposal and we want to draw attention to this problem. ### Dependencies no additional dependencies required Feel free to contact me or @timo282 and @finitearth if you have any questions. --------- Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	3 weeks ago

rick-SOPTIM	cd563fb628	community[minor]: passthrough auth parameter on requests to Ollama-LLMs (#24068) ... Thank you for contributing to LangChain! **Description:** This PR allows users of `langchain_community.llms.ollama.Ollama` to specify the `auth` parameter, which is then forwarded to all internal calls of `requests.request`. This works in the same way as the existing `headers` parameters. The auth parameter enables the usage of the given class with Ollama instances, which are secured by more complex authentication mechanisms, that do not only rely on static headers. An example are AWS API Gateways secured by the IAM authorizer, which expects signatures dynamically calculated on the specific HTTP request. **Issue:** Integrating a remote LLM running through Ollama using `langchain_community.llms.ollama.Ollama` only allows setting static HTTP headers with the parameter `headers`. This does not work, if the given instance of Ollama is secured with an authentication mechanism that makes use of dynamically created HTTP headers which for example may depend on the content of a given request. **Dependencies:** None **Twitter handle:** None --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	2 months ago
