AutoGen
The framework that popularized multi-agent conversation programming.
AutoGen pioneered agents that talk to each other (and to tools) to solve tasks. Microsoft is converging it with Semantic Kernel into the new Microsoft Agent Framework, which succeeds it.
Pros & cons
Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.
Pros
Cons
- DocsThe README says the project is archived and no longer maintained, warns that vulnerabilities may go unfixed, advises against production use, and points new users to Microsoft Agent Framework.[1]
- MetadataContributions are limited to bug fixes, security patches and docs, support is community-managed, and the last release (python-v0.7.5) was in September 2025.[1]
- User reportsA user says the v0.2-to-v0.4 rewrite split its APIs, so coding models mix incompatible versions; they rate it worst for AI-generated code.[1]
- User reportsOne developer used it only for demos and was unsure how to add production guardrails.[1]
- Best for
- Studying multi-agent conversation patterns, or maintaining an existing AutoGen deployment while you migrate.
- Watch out for
- Do not start new projects on it; it is archived. Check whether 'autogen' on PyPI resolves to the AG2 fork.
