GPT-5.6 Sol Pro

The highest-capability GPT-5.6 option for difficult tasks and longer-running workflows; in ChatGPT it powers the Pro setting of the reasoning slider. It has no separate public API model id — the developers.openai.com model page for gpt-5.6-sol-pro returns 404, only gpt-5.6-sol exists.

Дату отдельного анонса именно Sol Pro вендор не публикует; поколение GPT-5.6 раскатано на платные планы ChatGPT 9 июля 2026 (https://help.openai.com/en/articles/9624314-model-release-notes). Отсутствие API-страницы проверено: https://developers.openai.com/api/docs/models/gpt-5.6-sol-pro — 404.
