What are the best AI agent frameworks in 2026?

LangGraph for production workflows, CrewAI for quick prototypes, LlamaIndex if retrieval rules your world. Skip the rest unless they fit tight.

Does LangGraph beat CrewAI for memory?

Yes — native checkpointing crushes it, but add Mem0 for semantics. CrewAI's task memory fades fast.

Will AI agent frameworks consolidate soon?

Bet on it. Two survivors by 2027, like Kubernetes did for orchestration hell.
