Your AI and this story

  • GPT-6 Astra56 days after its cutoff
  • Claude Opus 5.5In its training data
  • Gemini 4 Hydrogen86 days after its cutoff
  • Grok 4.725 days after its cutoff

It is after the cutoff of GPT-6 Astra, Gemini 4 Hydrogen and Grok 4.7, and can be in the training data of Claude Opus 5.5.

Key facts

  • First reported by The Information and Axios on June 25, 2026
  • Request came from the Office of the National Cyber Director and the Office of Science and Technology Policy; Commerce Secretary Howard Lutnick reportedly advised against launching without cross-agency approval
  • Altman told staff the government would be ‘approving access customer by customer during this preview period’
  • Altman memo: ‘this is not our preferred long-term model’
  • Limited preview began June 26, 2026; broad release July 9, 2026 after administration approval

What happened

Citing GPT-5.6’s advanced capabilities and national-security implications, federal officials formally asked OpenAI to stagger its release. OpenAI shifted a planned June public launch to a limited preview for trusted partners, with the government signing off on access. After weeks of restricted access the administration approved the broad rollout, which happened on July 9.

Why it matters

The first time a US frontier-model release was explicitly gated by federal review — a de facto pre-deployment approval regime driven by cyber-offense concerns, arriving without new legislation.
