AutoGen

Microsoft's framework for multi-agent conversation systems

Live preview of microsoft.github.io/autogen

Overview

AutoGen was one of the first frameworks to treat agent-to-agent conversation as the unit of computation. Two or more agents talk; one might be a coder, another a critic, another a user proxy that executes code in a sandbox. The "conversation" is the trace of the work.

The strength is research-grade flexibility: almost any multi-agent pattern can be expressed. The cost is that you'll write more glue code than with CrewAI or LangGraph for the same workflow.

AutoGen v0.4 split the project into Core, AgentChat, and Extensions for cleaner separation of concerns.

Why We Recommend AutoGen

When the workflow doesn't fit a graph or a crew, AutoGen's conversation primitive is the most flexible escape hatch.
