Is gpt-5.2 the same as GPT‑5.2 Thinking?
Yes. OpenAI maps GPT‑5.2 Thinking to the API name gpt-5.2. Instant uses gpt-5.2-chat-latest, and Pro uses gpt-5.2-pro. When calling this model, select gpt-5.2; do not interpret it as Instant merely because it belongs to the chat category.
How do I use GPT‑5.2 to analyze images?

When is it worth using xhigh?
Complex code diagnosis, comparing solutions with multiple constraints, and difficult reasoning are better suited to trying xhigh. It emphasizes reasoning quality rather than applying the highest intensity to every simple question. Responses uses the reasoning configuration, while Chat Completions uses reasoning_effort; adjust them according to task difficulty and compare results.
How should I choose among the three entry points?
Use Chat Completions or Responses and provide the complete model ID. Chat Completions uses messages and choices, while Responses uses input and its corresponding response structure; handle history management, streaming events, and tool parameters separately according to the selected interface, and do not mix the two formats.
Can I have GPT‑5.2 output JSON or directly perform fixes?
Chat Completions can be configured for JSON or JSON Schema output, making it suitable for delivering classification results, issue lists, and analysis fields; your program still needs to validate the content. Performing fixes requires the application to provide tools and permissions; the model generating code or a function-call request does not mean that the modification has been completed or that tests have passed.
