OpenAI has agreed to stagger the public release of its latest AI model, GPT-5.6, after the Trump administration formally requested the company limit initial access to a select group of government-approved partners, citing the model’s advanced capabilities and national security implications.

The development, first reported by The Information on June 25, 2026, signals a new and uncertain era for AI model releases in the United States, where federal oversight is increasingly shaping how and when frontier AI reaches the public.

The government’s request to OpenAI follows a high-profile clash between the White House and rival AI company Anthropic earlier this month.

On June 12, 2026, the Trump administration issued an export control directive compelling Anthropic to take its latest models, Fable 5 and Mythos 5, entirely offline to prevent access by foreign nationals, citing serious national security concerns. Anthropic called the move a “misunderstanding” and said it hoped to restore access “as soon as possible,” but the precedent had been set.

Mythos, which had been distributed to roughly 40 organizations, including Google, Microsoft, and JPMorgan Chase, via a controlled initiative called Project Glasswing, raised alarms in Washington over its autonomous cybersecurity capabilities, specifically its reported ability to navigate multi-step attacks and pinpoint software vulnerabilities without human intervention.

GPT-5.6 Along With Mythos

According to a source familiar with the situation, both OpenAI and the administration view GPT-5.6 as “on par” with Anthropic’s Mythos in terms of advanced capabilities, particularly in cybersecurity. This alignment triggered the administration’s request for a controlled, staggered rollout rather than a broad public launch.

OpenAI CEO Sam Altman informed employees during an internal Q&A session on Wednesday, June 25, that GPT-5.6 would initially be released only to a limited group of enterprise partners.

In a subsequent internal memo, Altman stated the government would be “approving access customer by customer during this preview period.” The request came from two key federal bodies: the Office of the National Cyber Director and the Office of Science and Technology Policy. Commerce Secretary Howard Lutnick also reportedly advised OpenAI against launching without cross-agency approvals.

While OpenAI complied, Altman was clear that this arrangement is not sustainable long-term. According to The Information, Altman wrote in the memo: “We’ve made clear to the U.S. government that this is not our preferred long-term model, and will work with them and others in industry to achieve a more sustainable approach for future releases.”

A White House official told CNN they continue “to collaborate with frontier AI labs to develop shared approaches for addressing the challenges of scaling this technology.” The broader rollout of GPT-5.6 is expected a “couple of weeks” after the limited preview period, contingent on how the government-managed approval process proceeds.

The episode underscores a critical gap: there is currently no true federal regulatory framework governing the pre-release review of advanced AI models.

President Trump’s executive order on “Promoting Advanced AI Innovation and Security” calls on AI companies to voluntarily share frontier models with the government for cybersecurity review for up to one month before public release, but participation remains voluntary.

The arrangement with OpenAI, described as cooperative rather than legally mandated, may be the closest thing the industry has to a working model of government-AI collaboration, at least for now. How this preview period unfolds for GPT-5.6 could set the template for how every major AI lab releases powerful models going forward.
