OpenAI said it will publicly release its GPT-5.6 Sol, Terra and Luna models on Thursday, roughly two weeks after the artificial intelligence company limited the rollout to 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.
OpenAI also announced a new generation of voice models, called GPT-Live, on Wednesday. The company said the models can listen and speak at the same time, which means engaging with the models feels "much more like having a real conversation," according to a blog post.
Two versions of the voice models, GPT‑Live‑1 and GPT‑Live‑1 mini, are rolling out to ChatGPT users around the globe on Wednesday, OpenAI said.
OpenAI rolled out its GPT-5.6 series of models in June, and it initially agreed to release them to a select group of organizations whose "participation has been shared with the government," according to a blog post. The company said it believes in "broad access," and that it would work to make the models more widely available over the coming weeks.
"We don't believe this kind of government access process should become the long-term default," OpenAI said at the time. "It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them."
