OpenAI Opens GPT-5.6 to Everyone After Government Review Clears Public Launch

OpenAI will begin rolling out its GPT-5.6 family (Sol, Terra and Luna) to all users from Thursday, July 9, after U.S. authorities cleared the models for broad release following additional testing and government review. The announcement marks the end of an unusual six-week rollout during which OpenAI’s most advanced models were available only to a small group of approved organisations through the OpenAI API and Codex.
