FAQ

OffRail vs Vercel AI Gateway

Common questions about choosing OffRail over Vercel AI Gateway.

Can't find an answer? Contact us

Yes. OffRail is OpenAI-compatible, so the AI SDK's own `@ai-sdk/openai` provider works against it unchanged — you keep using `generateText` and `streamText`, just pointed at OffRail instead of the default gateway.
