OpenAI makes GPT-5.6 models available to everyone

OpenAI has now opened its GPT-5.6 Sol, Terra and Luna models to the general public. The company simultaneously introduced a fresh set of voice models known as GPT-Live.

OpenAI expands GPT-5.6 availability globally. The models reached ordinary users on Thursday, about two weeks after the firm had confined early access to only a "small group of trusted partners" at the request of the U.S. government. "Happy building," OpenAI CEO Sam Altman wrote in a post on X late Tuesday. The firm first introduced the GPT-5.6 lineup in June and at that point consented to supply the technology solely to chosen groups whose involvement "has been shared with the government."

New GPT-Live voice models enable simultaneous listening and speaking. Versions labeled GPT-Live-1 and GPT-Live-1 mini started reaching ChatGPT customers across the world on Wednesday. According to an OpenAI blog post the systems can process speech and generate replies at once, making exchanges feel "much more like having a real conversation."

Release follows government review process established in June. In June the company declared support for "broad access" and pledged to widen distribution in the weeks ahead. OpenAI added that it does not think this variety of government review "should become the long-term default" since it withholds advanced capabilities from users, developers, enterprises, cyber defenders and international partners. The firm called GPT-5.6 Sol its "strongest model yet" and noted superior performance in coding, biology and cybersecurity.

Timing aligns with rival Anthropic's restored model access. The wider debut arrives shortly after chief competitor Anthropic regained permission to offer its Claude Fable 5 and Mythos 5 models after a weeks-long dispute with officials. Anthropic had blocked those releases to meet an export control directive that the U.S. Department of Commerce removed late last month. OpenAI is broadening preview access to the GPT-5.6 models around the planet, the firm stated in a post on X late Tuesday.

Trump administration AI order shapes voluntary reviews. The Trump administration has assumed a larger part in AI rollouts since President Donald Trump issued an executive order on the topic in June. That directive calls on developers to supply their most advanced systems to federal reviewers for capability checks before general distribution and instructed agencies to craft an evaluation framework inside 60 days. OpenAI reported in June that it is collaborating with officials to shape assessment standards and create "a repeatable process for future model releases."
