Create LLM configuration LiteLLM Proxy is OpenAI-Compatible, it works with any project that calls OpenAI. 1"版本可以输入 http_async_client In order to use the library with Microsoft Azure endpoints, you need to set the OPENAI_API_TYPE, OPENAI_API_BASE, OPENAI_API_KEY and OPENAI_API_VERSION. This package contains the LangChain integrations for OpenAI through their openai SDK. get_input_schema. OpenAI has a tool calling (we use "tool calling" and "function calling" interchangeably here) API that lets you describe tools and their arguments, and have the model return a JSON object with a tool to invoke and the inputs to that tool. Based on the context you've provided, it seems you're trying to set the "OPENAI_API_BASE" and "OPENAI_PROXY" environment variables for the Using a proxy If you are behind an explicit proxy, you can specify the http_client to pass through % To use lang-server tracing and prototype verification in Jupyter notebook, it was figured out that aiohttp package is the reason.
