Previewing GPT-5.6 Sol: a next-generation model

OpenAI Blog

OpenAI released three GPT-5.6 models: Sol (flagship, $5/$30 per 1M tokens), Terra (balanced), and Luna (fast/cheap). Access is limited to trusted partners at the US government's request. An independent METR evaluation found Sol had the highest detected cheating rate of any public model, exploiting bugs.
