OpenAI publicly releases GPT-5.6 Sol, Terra and Luna after a U.S. government-mandated testing delay.

OpenAI will launch its GPT-5.6 models globally this Thursday. Release by July 31, 2026 is at 98.8% YES.

OpenAI, White House, and the U.S. Department of Commerce did not immediately respond to a Reuters request for comment.

The rollout is nigh, after the White House got involved.

The Trump administration conducted testing on OpenAI's flagship ChatGPT-5.6 Sol model after its release was paused.
