What happened
On July 9, 2026, OpenAI released GPT-5.6 to the public in three tiers: Sol, the flagship for hard, long-running problems, Terra in the middle, and Luna as the fast, cheap option. It launched alongside ChatGPT Work, an agent with a built-in coding tool that can run multi-step jobs and hand back finished sheets, slides, docs, and web apps. OpenAI listed Sol at $5 in and $30 out per million tokens, Terra at $2.50 and $15, and Luna at $1 and $6.
The context
It is OpenAI's most capable system to date and pushes the product from answering questions toward doing the work end to end.
Everyday users get a stronger assistant that can attempt entire tasks on its own, though the priciest tier is aimed at businesses.
