Pro has a different output allowance and tool set

Its model page lists a 400,000-token window and a 272,000-token maximum output. It does not support Code Interpreter. Requests may take several minutes, so the documentation recommends background mode for long-running work.GPT-5 Pro official model documentation

Review an existing integration

Practical guidance. When migrating a difficult analysis task, check the actual tool set rather than assuming every Pro model has identical tools. Preserve the request identifier and completion state. Compare whether the result resolves the original question with reviewable evidence.
