OpenAI has done something it has never done before: pump the brakes on a product launch because the government asked nicely.

On June 26, the company unveiled a limited preview of its GPT-5.6 model family, which includes a variant called Sol, but restricted access to a small group of vetted enterprise partners. The reason? The Trump administration requested that OpenAI stage the rollout to allow federal authorities time to review and test the model’s advanced capabilities before it reaches the general public.

CEO Sam Altman acknowledged that the limited rollout complies with federal requests, a framing that stands in stark contrast to every previous OpenAI launch.

What the government is worried about

The administration’s concern centers on GPT-5.6’s capabilities in sensitive domains. Coding, biology, and cybersecurity are the specific areas flagged for review.
