OpenAI to stagger GPT-5.6 release at US government request

Summary: Reporting on 2026-06-25 (single-sourced) says OpenAI will stagger the release of GPT-5.6 after a request from the Office of the National Cyber Director and the Office of Science and Technology Policy. Sam Altman reportedly told staff GPT-5.6 will enter a limited preview for a small set of enterprise customers, with the government approving access customer by customer during the preview. The request maps onto Executive Order 14409 (signed 2026-06-02), which asks developers to give the government up to 30 days of pre-release access to their most capable models.
Why it matters: It is one of the first public cases of a US agency coordinating directly on a frontier model release sequence, a more permissive posture than the foreign-access limits placed on Anthropic Fable 5 and Mythos 5.
Follow-up: Watch for OpenAI confirmation, the preview scope and timeline, and how the EO 14409 pre-release review applies to other labs.
