FAQ

API Call Issues

Why can't I use gpt-5.2-pro?

The gpt-5.2-pro model only supports OpenAI's Response API (/v1/responses), not the traditional Chat Completions API (/v1/chat/completions).

Solutions:

• If your application supports the Response API, use the /v1/responses endpoint
• If your application doesn't support the Response API, use gpt-5.2 instead, which maintains /v1/chat/completions compatibility

For more details, see OpenAI Compatible API Documentation (Sidebar: API Reference → OpenAI Compatible API).
