OpenAI has delayed the full public launch of its latest AI model, GPT-5.6, at the request of the U.S. government. The company announced on June 26 that initial access will be restricted to a small group of trusted partners, whose details have been shared with authorities.
The decision underscores growing concerns in Washington over the national security risks posed by advanced AI systems. U.S. officials aim to identify potential threats, including cyberattacks and military misuse, before the tools are widely deployed. OpenAI stated that this limited release is a temporary measure while it works with the Trump administration to develop a broader framework for future model launches.
President Donald Trump signed an executive order earlier this month, establishing a voluntary framework for AI developers to offer "covered frontier models" to the U.S. government for up to 30 days before releasing them to trusted partners. OpenAI expressed concern that such government oversight should not become a permanent standard, as it could restrict access to advanced AI tools for developers, businesses, and international partners.
The new lineup includes GPT-5.6 Sol, OpenAI's most advanced model yet, alongside mid-tier Terra and fast, affordable Luna. The company plans to continue rigorous testing and close coordination with partners as it prepares for a wider release in the coming weeks. OpenAI did not disclose the names of its partners.
The announcement follows recent actions against rival Anthropic, which was forced to disable access to its latest models, Mythos and Fable, due to export control directives from the Trump administration. Anthropic is currently in negotiations with U.S. officials but has not provided a timeline for restoring access.
