For setup and usage, refer to the guides listed on this page. ## LLM providers

**Using LangChain?** LangChain provides a unified interface to 100+ LLM providers, which allows you to switch between models by setting environment variables. [Initialize a model](/oss/python/langchain/models#initialize-a-model) and LangSmith will automatically trace your application. ## Agent frameworks
