OpenAI has launched its new GPT-5.6 models—Sol, Terra and Luna—in a limited preview for trusted partners after a US government request, pending a framework for evaluating advanced AI. The company plans a wider rollout across ChatGPT, API and Codex in the coming weeks while opposing permanent government preview requirements for future AI releases.
New Delhi: US-based AI company OpenAI has announced that new GPT‑5.6 models, such as Sol, Terra and Luna, will be rolled out with a limited preview for trusted partners, with a wider release planned in the coming weeks.
These models bring advances in reasoning, coding and cybersecurity, according to the company.
OpenAI said it briefed the US government on GPT‑5.6’s capabilities before launch and agreed to the government’s request of a limited launch, while federal authorities develop a broader framework for evaluating advanced models under a recent cybersecurity executive order, according to multiple reports.
The company said it intends to make the models available across ChatGPT, the API and Codex in the coming weeks, and added that it does not want government preview requirements to become a permanent standard for frontier AI releases.
