GPT-5.6 goes public July 9 with full-duplex voice.
Story
Two weeks after a government-requested limit to "trusted partners," OpenAI confirmed the full GPT-5.6 family (Sol, Terra, Luna) goes public, with Altman marking it "Happy building." Alongside it, GPT-Live-1 listens and speaks simultaneously for genuine conversational turn-taking. The real signal for builders is the government-hold-then-release pattern. Frontier launches are now gated by national-security review, which is a new variable in your roadmap planning.
