OpenAI Unveils GPT-5.6 Sol, Terra and Luna Models — but only Accessible to Limited Preview Partners for Now, per US Gov
OpenAI says the new models include stronger reasoning and safety protections, with Sol aimed at coding, biology and cybersecurity.
- Today, OpenAI launched a limited preview of the GPT-5.6 series, featuring flagship model Sol, Terra, and Luna, with access restricted to a small group of approved partners.
- Following a June 2 Executive Order, The Trump administration is enforcing a new benchmarking process for frontier AI models, mirroring restrictions previously applied to Anthropic's Claude Mythos and Claude Fable.
- Flagship Sol features OpenAI's "most robust safety stack yet," hardened through over 700,000 A100 GPU-equivalent hours of automated testing, alongside new "Max" and "Ultra" modes for complex workflows.
- Despite pushing back against the administration's request to hold the model back, OpenAI agreed to the limited preview while working through the required security vetting process.
- GPT-5.6 will be available in ChatGPT, Codex, and the API "soon," though the company has not yet shared a specific timeline for broader public rollout.
