AutoGen (Microsoft)

Microsoft's open-source framework for building multi-agent AI systems — agents can converse, write and execute code, collaborate in groups, and use tools in configurable chat patterns.

Code execution by default uses local subprocess — major security risk in production. Always use Docker-sandboxed code executor. Secrets managed via environment variables. MIT licensed with active Microsoft security practices for dependencies.

Best When

You need complex multi-agent collaboration patterns, especially code-generating agents that execute and iterate on their output.

Avoid When

Your use case is straightforward — CrewAI or PydanticAI have simpler APIs for standard agent patterns.

Use Cases

  • Code generation workflows where an agent writes and another executes and tests
  • Multi-agent research tasks with specialized agents (critic, planner, executor)
  • Automated software engineering with code-executing agents in sandboxes
  • Group chat agent patterns where multiple agents debate and refine solutions
  • Building custom agent topologies for complex problem solving

Not For

  • Simple single-agent tasks (significant framework overhead for basic use cases)
  • Real-time latency-sensitive applications (multi-agent conversation adds significant latency)
  • Production systems requiring strict output determinism

Authentication

Methods: api_key
OAuth: No Scopes: No

Passes through to underlying LLM providers. Multi-provider support (OpenAI, Anthropic, Azure OpenAI, Gemini, local models via Ollama). Config-driven model selection.

Pricing

Model: open_source
Free tier: Yes
Requires CC: No

Framework is free. Primary costs are LLM API calls — multi-agent systems can use significant token budgets due to cross-agent communication.

Known Gotchas

  • AutoGen v0.2 vs v0.4 (AgentChat) have very different APIs — breaking changes between major versions
  • Code execution requires Docker or a sandboxed environment — default local execution is a security risk
  • Group chat agent selection can be non-deterministic — conversations may not converge predictably
  • Token costs grow super-linearly with number of agents (each sees full conversation history)
  • Infinite loops are possible if termination conditions are not carefully set
