# US government asks OpenAI to limit GPT-5.6 release to approved partners

On June 25, 2026 it emerged that the Trump administration (Office of the National Cyber Director and OSTP) had asked OpenAI to restrict GPT-5.6's initial release to government-approved partners over its cyber capabilities; OpenAI complied with a customer-by-customer approved preview from June 26 and received clearance for a broad launch on July 9.

## 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.
