LangChain has a lot of chat model integrations, and it can be hard to remember how to import each.

To make things simple, we've added a universal model initializer in LangChain for Python and JavaScript. This lets you use any common chat model without having to remember different import paths and class names.

Use it with OpenAI, Anthropic, Gemini, Bedrock, Cohere, and more!
