Framework vs. agent vs. model
A framework is a library or orchestration system developers use to build agents — it is not itself an end-user product. LangChain, LangGraph, CrewAI, and AutoGen appear here because their repository identity is verifiable, not because this site scores which one is "best"; the right framework depends on the orchestration pattern a specific project needs, which is not a fact this directory can determine in the abstract.
