🧪 Been watching a question come up everywhere this month: can you actually build production AI agents with vibe coding tools in frameworks like LangGraph, LangChain, Autogen, OpenAI SDK, or CrewAI?
Short answer: yes — but the landscape just shifted hard.
✅ LangChain + LangGraph both hit 1.0 in October 2025
❌ Autogen moved to maintenance mode (Microsoft's new stack is MAF)
⚡ OpenAI Agents SDK shipped major sandbox + harness update last week
The 70/30 rule still holds: these tools save 70% of the time on scaffolding and glue, and hallucinate on the remaining 30% (orchestration, state bugs, framework-specific gotchas).
My take for agency owners: learn LangGraph first. Skip LangChain as a starter. Skip Autogen entirely.

🤔 Curious — anyone here building agents with Cursor or Claude Code? Which framework are you using, and where has it bitten you?
