LangGraph vs CrewAI vs OpenAI Agents SDK 2026: Which AI Agent Framework?
A practical 2026 comparison of the three main ways to build AI agents in Python — LangGraph (the low-level, stateful graph runtime for maximum control and durable execution), CrewAI (the high-level, role-based framework where you assemble a crew of agents with roles and tasks), and the OpenAI Agents SDK (a minimal, unopinionated set of primitives — agents, handoffs, guardrails, and sessions). Control vs convenience, state and durability, multi-agent orchestration, model lock-in, observability, learning curve, and which to ship in the AI templates and starters you sell.
