We tested 8 AI agent frameworks in production across healthcare, logistics, and fintech. Here’s what actually works - and what breaks when real users show up. Six months ago, picking an AI agent framework meant choosing between LangGraph, CrewAI, and AutoGen. That was the entire conversation. Now every major AI lab ships its own agent SDK. OpenAI, Anthropic, and Google all launched agent development kits in 2026. Microsoft rebuilt AutoGen from scratch. LangGraph hit 126,000 GitHub stars. CrewAI raised funding and shipped enterprise features.
