LangChain Python integrations | LangChain Español

LangChain offers an extensive ecosystem with 1000+ integrations across chat & embedding models, tools & toolkits, document loaders, vector stores, and more.

A provider is a company or platform that hosts AI models and exposes them through an API (e.g., OpenAI, Anthropic, Google). Many providers have a dedicated langchain-<provider> package that implements one or more of LangChain's standard interfaces—chat models, embedding models, vector stores, and more—giving you a consistent API regardless of the underlying provider. Install the package, pick a model name, and swap providers without changing your code.

To see a full list of integrations by component type, refer to the categories in the sidebar.

Tip

For a conceptual overview of how providers and models work in LangChain, including how to find model names, use new models immediately, and work with routers—see Providers and models.
