OpenAI Previews GPT-5.6

OpenAI introduced a limited preview of GPT-5.6, a new model family led by Sol, its next-generation frontier model, alongside Terra and Luna for cheaper, higher-volume work.

• Three tiers: Sol is the flagship for ambitious agentic work, Terra delivers GPT-5.5-competitive performance at 2x lower cost, and Luna is the fastest, most affordable option for high-volume tasks.
• Agentic SOTA: Sol sets a new state of the art on Terminal-Bench 2.1, which tests complex command-line workflows requiring planning, iteration, and tool coordination.
• Security frontier: Billed as OpenAI's most capable model for cybersecurity, Sol shifts the performance-efficiency frontier on long-horizon tasks like vulnerability research and exploitation.
• Gated rollout: At the request of the US government, OpenAI is starting with a limited preview for trusted partners in Codex and the API, with general availability planned in the coming weeks.
