US delays launch of OpenAI's GPT-5.6 Sol
The launch of OpenAI's latest AI model, GPT-5.6 Sol, has been postponed by the US government citing national security concerns and geopolitical dependency risks.

What happened?
The US government, under President Donald Trump’s administration, has delayed the broad release of OpenAI's new AI model, GPT-5.6 Sol. Access will initially be restricted to selected users and trusted partners. OpenAI describes GPT-5.6 Sol as its most advanced model to date, with specific focus on programming, biology, and cybersecurity.

”The launch of OpenAI's most advanced model yet, GPT-5.6 Sol, faces delays amid rising concerns over government intervention and geopolitical reliance, highlighting the shifting landscape of AI security and strategic control.”
”the US government under President Donald Trump has halted the model’s broad release on national security grounds, leaving only selected users and trusted partners with early access.”
Why it matters
The delay stems from growing concerns regarding state intervention, control over AI technology, and geopolitical dependency. The decision highlights a shift in views on AI safety and strategic control, as governments seek greater influence over the distribution and deployment of advanced AI models.
Who is affected?
The delay primarily impacts OpenAI, whose new model is now restricted, as well as the wider community of developers, enterprises, and users awaiting GPT-5.6 Sol. It also involves the US government, which is taking a more active role in the regulation of AI technology.
What else you should know
Similar restrictions were implemented in June for Anthropic's models Fable 5 and Mythos 5, which were later granted broader access. This indicates a pattern where the government initially limits access to frontier AI models.
