By Agentic Weekly, operated independently from Texas, US · Last updated (America/Chicago) · How we work
Microsoft's open-source multi-agent framework; its README now says the project is in maintenance mode and points to Microsoft Agent Framework.
AutoGen's README says the project is no longer actively developed with new features, warns that without ongoing maintenance and security fixes vulnerabilities may remain unaddressed, and links an AutoGen to Microsoft Agent Framework migration guide. The latest release tag we saw is python-v0.7.5 from Sep 30, 2025.
What it does well: MIT-licensed code; Large community.
Where it falls short: Maintenance mode per its own README; Last release tag we saw is from Sep 2025; Our test was one small task on a local 3B model; it does not show behaviour with hosted models or larger jobs.
Latest version we cover: python-v0.7.5 (Sep 30, 2025). Vendor: Microsoft.
When to look beyond AutoGen
Skip AutoGen if:
You are starting a new production project: Microsoft points to Agent Framework instead
Existing AutoGen projects that need reference material
Researchers studying multi-agent patterns
AutoGen: Official page, dated. Open-source library; costs come from the model APIs you call. Evidence: Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B)).
Before you switch, note what we could not verify about AutoGen:
Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B))
Official page, dated
n/a
Evidence labels: Reported means written from official sources; Tested means a small smoke test with its scope stated. See methodology. Pricing status shows how well we could verify prices; open each tool page for the note.
Verdict: Reasonable if you like the crew-of-agents mental model; the memory and tool-loop fixes in this release are worth taking.
Pick CrewAI if: Developers who want role-based multi-agent flows; Teams that want a built-in eval command.
For agent building: CrewAI is #5, AutoGen is not ranked.
Latest release we cover: CrewAI 1.15.30 on Oct 23, 2026. AutoGen python-v0.7.5 on Sep 30, 2025.
Evidence: CrewAI: Tested (smoke test, 2026-10-25, local Qwen2.5-3B-Instruct, not vendor models). AutoGen: Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B)).
Strength: CrewAI: MIT license and a large GitHub following. AutoGen: MIT-licensed code.
Main caveat: CrewAI: Very fast release cadence (several versions per week). AutoGen: Maintenance mode per its own README.
Verdict: A dependable foundation for stateful agents; this release is a routine fix, so only update if the RemoteGraph or recursion fixes affect you.
Pick LangGraph if: Developers who want explicit control over agent state and flow; Teams running long-lived, resumable agents.
For agent building: LangGraph is #3, AutoGen is not ranked.
Latest release we cover: LangGraph 1.2.17 on Oct 24, 2026. AutoGen python-v0.7.5 on Sep 30, 2025.
Evidence: LangGraph: Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B)). AutoGen: Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B)).
Strength: LangGraph: MIT license, large community. AutoGen: MIT-licensed code.
Main caveat: LangGraph: More concepts to learn than simpler SDKs. AutoGen: Maintenance mode per its own README.
Verdict: Vercel's TypeScript SDK that gives one API across many model providers, with streaming and agent helpers.
Pick Vercel AI SDK if: TypeScript and Next.js teams building chat or agent UIs.
For agent building: neither Vercel AI SDK nor AutoGen has an editorial rank in this category.
Pricing model: Vercel AI SDK is Free and open source; AutoGen is Free and open source.
Free tier: Vercel AI SDK: Free to self-host. AutoGen: Free to self-host.
