- R · What Makes It Special
- GPT-5.6 Sol (July 9, 2026), the flagship of OpenAI's GPT-5.6 family alongside the cheaper Terra and the faster Luna, built for complex professional work: a 1.05M-token context, 128K output tokens, reasoning effort up to max and an ultra mode that runs four agents in parallel. OpenAI reports 64.6% on SWE-Bench Pro, 88.8% on Terminal-Bench 2.1 and 7.78% on ARC-AGI-3; it also runs on Cerebras at up to 750 tokens a second, and OpenAI says Sol's own kernel work cut its serving cost by 20%.
