Comparing Vercel AI SDK, LangGraph, OpenAI Agents SDK
| Attribute | Vercel AI SDK | LangGraph | OpenAI Agents SDK |
|---|---|---|---|
| What it is | Vercel's TypeScript toolkit for building AI apps and agents. It gives one provider-agnostic API for models, plus tool calling and multi-step agent loops. | LangGraph is a low-level Python/JS framework for building agents as explicit graphs of steps. It is built for long-running, stateful agents where you need to pause for a human and resume later. | OpenAI's open-source Python SDK for multi-agent apps. Its core ideas are agents, handoffs between them, and guardrails on inputs and outputs, which map neatly onto triage-then-specialist support flows. |
