OpenAI Agents SDK vs Claude Agent SDK
You are picking the official agent SDK from a model lab. The trade-off is GPT vs Claude as your primary model 鈥?and the SDK ergonomics that come with it.

Claude Agent SDK
Build agents with tool use, computer use, MCP, and Anthropic's safety primitives — Python and TypeScript.
Read review →Our take
For raw reliability on tool use and the broadest model selection, OpenAI. For safer long-horizon tasks, computer use, and arguably better reasoning at the top end, Claude. The honest answer for production: build one abstraction layer of your own, swap models freely, do not lock into either SDK pattern as if it were a framework.
- OpenAI Agents SDK wins 1
- Claude Agent SDK wins 2
- Ties: 3
Side-by-side
| OpenAI Agents SDK | Claude Agent SDK | |
|---|---|---|
| Tool use reliability | Strong, broad model coverage | Strong, with rich tool primitives |
| Computer use | Computer Use API | Computer use sandbox is your problem |
| MCP support | Yes | First-class |
| Safety primitives | Standard | More opinionated, constitution-shaped |
| Lock-in | High (SDK is the point) | High (SDK is the point) |
| Best paired with | OpenAI models, Azure | Anthropic models, AWS Bedrock |
