About gpt-5.6-sol

GPT-5.6 Sol is the GPT-5.6 family model aimed at complex professional work. Its official text and image inputs produce text, making it a candidate for code analysis, option comparison and multi-step workflows. Evaluate completion quality and reasoning overhead on representative tasks.

Use the specific model name shown here. The official gpt-5.6 alias does not establish how a third-party route maps names. Check reasoning, structured output and tools against the selected interface; use this site’s group prices and usage records for cost decisions.

Official reference, checked 2026-10-14.

Use cases and prompting

For code analysis, provide relevant files, the failure and acceptance criteria. Ask for verified facts separately from assumptions.
Split multi-step work into inspectable intermediate results before combining the final recommendation.
Reuse the same samples when changing reasoning effort. Record completion rate, latency, output and reasoning usage rather than answer length alone.
Compare tasks with GPT-5.6 Terra or GPT-6.1 Sol. See the integration guide.
