What you get

What you get

  1. 01Build agents that use tools and data
  2. 02Answers grounded in your own documents (RAG)
  3. 03Switch model providers without rewriting everything

For you if …

  • Python developers building AI applications
  • Teams who need lots of integrations

Pick something else if …

  • Need just one simple API call? The provider's SDK is enough

How to start

In three steps.

What you need
  • Python 3.10 or newer
  • A model API key
  • Python skills
  1. 1Install with pip install langchain plus your provider's package
  2. 2Connect a model, e.g. with init_chat_model
  3. 3Build a chain or an agent following the examples in the docs
