About this tag
GPT-5.6 is a family of AI models from OpenAI that reached general availability on July 9, 2026, with three tiers: Sol, Terra, and Luna. The models are integrated into ChatGPT, Codex, and the OpenAI API, and have become the preferred model for Microsoft 365 Copilot, affecting Word, Excel, and PowerPoint. Discussions on WindowsForum cover practical aspects such as outcome-first prompting to reduce API token usage, the lifting of a five-hour usage limit for Sol on paid plans, and the model's role in enterprise workflows like ChatGPT Work. A notable claim involves Sol Ultra generating a proof for the Cycle Double Cover Conjecture, pending peer review. The tag also touches on cost management and model routing in enterprise AI deployments.
