GPT-5.6 access: OpenAI ships its newest model one approved customer at a time
AnalysisA frontier model now reaches paying users only after a federal office signs off on each one. OpenAI put GPT-5.6 into limited preview on June 26 in three tiers, Sol for hard problems, Terra for everyday use, and Luna for cheap high-volume calls, with Sol priced at $5 per million input tokens. Then the Office of the National Cyber Director and the Office of Science and Technology Policy capped early access at roughly 20 vetted partners. Executive Order 14409, signed June 2, insists it creates no licensing requirement. Sam Altman told staff the government approves access one customer at a time, which is a license wearing a plainer coat.
