OpenAI GPT-5.6 Sol, Terra, and Luna: July 9 Public Launch After First-Ever U.S. Government-Gated Approval

• CAISI clearance: The Commerce Department's CAISI conducted safety testing on the GPT-5.6 family and approved the broad rollout on July 7, 2026, clearing the way for the July 9 public launch .
• Trump administration's role: The White House Office of Science and Technology Policy (OSTP) and the Office of the National Cyber Director (ONCD) jointly requested the staged rollout in June, citing national security concerns — making it the first documented case of the executive branch restricting a frontier AI model's commercial release . Axios reported the approval came after "additional testing" and meetings between OpenAI and government officials .
• Prior restriction: From June 26 onward, OpenAI limited access to approximately 20 government-vetted organizations, accessible only through the API and Codex, with ChatGPT users entirely excluded .
• Executive Order foundation: The Trump administration invoked Executive Order 14409, signed June 2, 2026, to require OpenAI to stagger the public release so the government could vet which partners get early access .

Sol's capabilities and pricing

• Capabilities: Sol is the flagship model, described by OpenAI as its "strongest model yet" . It scored 91.9% on TerminalBench 2.1, beating both Claude Fable 5 and GPT-5.5 . On ExploitBench, Sol matched Anthropic's Mythos Preview using only one-third the output tokens . All three GPT-5.6 models cleared "High" ratings in both biological and cybersecurity capability for the first time in any OpenAI model family — the core reason for government scrutiny .
• Pricing per 1M tokens :
  • Sol: $5 input / $30 output
  • Terra: $2.50 input / $15 output (half the cost of GPT-5.5 with competitive performance)
  • Luna: $1 input / $6 output (fastest, cheapest tier)
• New features: The lineup introduces a "maximum reasoning effort" setting and an "ultra mode" (also called "super mode") that uses sub-agents to parallelize complex tasks .
• Cerebras launch: GPT-5.6 Sol will also launch on Cerebras at up to 750 tokens per second in July, with initial customer access limited as capacity expands .

Regulatory precedent

• First-ever government-gated AI launch: This was the first time OpenAI voluntarily restricted a model's commercial release at a direct White House directive, following the earlier precedent set when the Trump administration imposed similar restrictions on Anthropic's Mythos model .
• OpenAI's position against permanence: OpenAI explicitly stated it does not want this kind of government access process to become the long-term default, writing: "We don't believe this kind of government access process should become the long-term default" .
• Emerging framework: The CAISI testing-and-approval pathway used for GPT-5.6 — federal safety review, conditional clearance, and staged rollout — mirrors the structure outlined in Trump-era executive orders on AI safety and is expected to serve as a template for future frontier model releases .

Key caveat

Reuters noted on July 8 that Axios's report on the Commerce Department approval could not be independently verified by Reuters at that time . However, the July 9 public launch has since been confirmed across multiple outlets including OpenAI's own announcements and major news organizations .
