AutoGen (Microsoft) (microsoft.github.io) Review

AutoGen is Microsoft's open-source programming framework for building AI agents and multi-agent applications in Python. Its layered architecture includes AgentChat for high-level conversational agents and AutoGen Core for low-level distributed agent runtimes, plus AutoGen Studio, a no-code interface for prototyping agent workflows. The project is maintained on GitHub under the MIT license and is free to use, with agents able to call models, tools, and human input across asynchronous, event-driven systems. AutoGen suits researchers and developers building custom agentic systems who want a code-first framework backed by an active open-source community rather than a managed platform.
