Editor’s Note: Welcome to Prompt, your weekly briefing on the shifting AI landscape. We provide an analytical look at the week’s biggest developments, paired with a curated roundup of the stories that actually matter.
For the past few years, the AI conversation has focused on building larger models. This week, the focus shifted to something else entirely: who controls them.
Anthropic was forced to disable access to some of its newest models after U.S. government restrictions raised national security concerns about access to advanced AI capabilities. The move highlights a growing reality for the industry: frontier AI models are increasingly being treated less like software and more as strategically important infrastructure.
In a June 12 statement, Anthropic said the Trump administration directed the company to suspend access to its Fable 5 and Mythos 5 models for foreign nationals after raising national security concerns. Anthropic said it understood the issue involved a potential technique for bypassing the models’ safety controls.
The decision also sparked criticism from some security researchers, who argued that restricting access to frontier AI models could slow defensive cybersecurity efforts.
The move was particularly notable because Anthropic had already restricted access to Mythos 5 through Project Glasswing, an initiative aimed at limiting misuse of the model’s advanced cybersecurity capabilities.
The Anthropic dispute is not occurring in isolation. Instead, it reflects a broader shift in which access, control and sovereignty may matter as much as model performance.
Similar themes emerged elsewhere this week. A new IBM study found that many organizations view AI sovereignty as a strategic priority but lack visibility into the infrastructure supporting their AI systems. Meanwhile, lawmakers in the U.K. called for a national digital sovereignty strategy to reduce dependence on foreign technology providers.
For much of the past two years, the AI race has been defined by bigger models, larger funding rounds and increasingly capable systems. This week’s developments suggest the next phase may focus on a different question entirely: who gets access to advanced AI systems, who controls them and under what conditions.
