OpenAI is limiting preview access to its latest GPT models at the request of the US government. The company said it previewed the capabilities of its new series of GPT-5.6 models, which includes Sol, Terra, and Luna, to the US government ahead of Friday's launch. "At their request, we are starting with a limited preview for a small group of trusted partners whose participation has been shared with the government, before releasing more broadly," the company said. OpenAI said they were complying as part of its earlier agreement with the Defense Department, which allows the Pentagon to use its AI models. Introducing a limited preview of GPT-5.6 Sol, our next generation frontier model, as well as GPT-5.6 Terra, a balanced model for efficient, everyday work, and GPT-5.6 Luna, a fast and affordable model for high-volume work. — OpenAI (@OpenAI) June 26, 2026 OpenAI, however, said such a process shouldn't become "the long-term default."
