What is AutoGen?
AutoGen is an open-source framework by Microsoft for building multi-agent systems where agents collaborate through structured conversations — supporting customizable agents, human-in-the-loop patterns, and complex multi-agent workflows.
WHY IT MATTERS
AutoGen models multi-agent interaction as conversations. Agents exchange messages, with each agent having its own system prompt, tools, and capabilities. A 'group chat' manager coordinates which agent speaks next, creating structured multi-agent dialogues.
The framework supports various agent types: AssistantAgent (LLM-powered), UserProxyAgent (human-in-the-loop), and custom agents. AutoGen 0.4 introduced an event-driven architecture with better support for production deployments.
For financial applications, AutoGen's conversational model lets you design workflows where agents discuss and verify financial decisions before execution — a research agent presents findings, an analyst agent evaluates risk, and a human proxy approves the final action.
HOW POLICYLAYER USES THIS
PolicyLayer adds spending controls to AutoGen multi-agent conversations that involve financial actions. When an agent in the conversation proposes a financial transaction, PolicyLayer validates it before execution.
