About gpt-5-mini
gpt-5-mini is the smaller GPT-5 version for clearly specified tasks, with text and image input, text output and reasoning support. Existing extraction, constrained question answering and code assistance workflows can retain it as a versioned reference.
OpenAI currently points new low-latency, high-volume projects toward GPT-5.6 Terra. Choose using task accuracy and measured latency, and budget context for reasoning and answers.
Official reference, checked 2026-10-14.
Use cases and prompting
- Define fields, a few examples and missing-value rules, then validate the parsed object.
- Supply allowed sources for constrained answers and require an unknown result when evidence is absent.
- Record reasoning settings and output budgets and use failure cases to assess escalation.
- Compare the same test cases with gpt-5.6-terra; check request and response formats in the API documentation.
