-To use [LiteLLM](https://www.litellm.ai/), set the configs as outlined in the [doc](https://docs.litellm.ai/docs/set_keys). In `LiteLLMProvider`, you can pass `api_base` and `api_key`. The value of these configs will depend on your setup. For example, if you are using OpenAI models, then you need to pass `https://api.openai.com/v1` as the `api_base` and your OpenAI API key as the `api_key`. If you are using a LiteLLM proxy server running on your local machine, then you need to pass `http://localhost:<port>` as the `api_base` and your LiteLLM API key as the `api_key`.
