GPT-5.6 Sol
OpenAI's flagship tier, GA 9 Jul 2026. The 5.6 generation replaced the old one-model-with-a-dial approach with three durable tiers — Sol (flagship), Terra (balanced), Luna (cheap) — and `gpt-5.6` is now an alias for `gpt-5.6-sol`. There is no separate Pro model ID; Pro is a reasoning mode on Sol. Artificial Analysis Intelligence Index 61.0, SWE-bench Verified 88.1%, SWE-bench Pro 66.4%, Terminal-Bench 2.1 72.9%. 1.05M context (922K input / 128K output). Pricing holds at $5/$30 with cache reads at 10% of input; requests over 272K tokens move to a long-context meter at $10/$45.
