**Short answer.** LangGraph is a graph runtime for explicit control flow with persistence and human-in-the-loop, and is model-agnostic. The OpenAI Agents SDK is a small, opinionated library (agents, handoffs, guardrails, tracing) that is simplest with OpenAI models. CrewAI is role-based multi-agent orchestration for teams of agents with defined tasks. Pick by how much control flow you want to write yourself.

## Comparison

| | LangGraph | OpenAI Agents SDK | CrewAI |
| --- | --- | --- | --- |
| Mental model | State graph | Agents with handoffs | Crew of role agents |
| Model support | Any | OpenAI first, others via adapters | Any via LiteLLM |
| Persistence and replay | Built in (checkpointers) | Sessions | Memory modules |
| Human in the loop | First-class | Guardrails | Limited |
| MCP | Yes | Yes | Yes |
| Best for | Complex, auditable workflows | Fast start on OpenAI | Parallel role-based teams |

## Guidance

- If you can draw the workflow as a flowchart with loops, LangGraph.
- If one model, a few tools, and handoffs cover it, the Agents SDK.
- If the task decomposes into roles (researcher, writer, reviewer), CrewAI.
