- OpenAI has received U.S. government approval for a broad release of its GPT-5.6 model.
- The initial launch was restricted to approximately 20 organizations approved by the U.S. government.
- The phased release is a result of government requests and ongoing testing.
- GPT-5.6 includes models named Sol, Terra, and Luna.
The U.S. Department of Commerce has approved a broad release of OpenAI's advanced GPT-5.6 model, according to reports. This follows an initial limited preview where access was granted to approximately 20 organizations whose participation was approved by the U.S. government. OpenAI had previously delayed a full public launch at the government's request, limiting initial access to vetted partners.
The GPT-5.6 model family includes three distinct models: Sol, described as OpenAI's strongest; Terra, a balanced model offering GPT-5-level performance at a lower cost; and Luna, a fast, low-cost option. The release strategy marks a departure from typical launches, with the government playing a role in managing access to this frontier AI model.
This phased rollout is part of a broader effort by the U.S. government to oversee the development and deployment of advanced AI, treating these models as strategic national security assets. This approach, termed 'soft nationalization' by some observers, involves government oversight and potential delays or restrictions on releases based on testing and cyber capabilities. OpenAI has expressed concerns that such processes could limit access for users and developers.
