AI Model Blocked Over National Security Fears
13 Jun
Summary
- Government ordered foreign national access suspension.
- National security concerns cited for AI model restrictions.
- Company disagrees with government's recall decision.
An AI company has ceased access to its Fable 5 and Mythos 5 models for all foreign nationals. This directive, issued by the US government on Friday, June 12, 2026, is attributed to national security concerns.
The company, Anthropic, believes the government's order stems from reports of a jailbreaking method for Fable 5, a recently launched AI model. Mythos 5 is its advanced cybersecurity model available to select partners. The Fable AI model, released on June 9, 2026, reportedly surpasses previous models in capabilities.
Anthropic stated it implemented significant safeguards to prevent misuse, noting user complaints about their overbreadth. The company acknowledges that no model is entirely immune to jailbreaks. It also mentioned receiving verbal evidence from the government regarding a potential narrow jailbreak.
Despite the government's actions, Anthropic disagrees that a potential vulnerability justifies recalling a commercial product. The company advocates for a transparent and fact-based statutory process for blocking unsafe AI deployments, asserting that the current action lacks these principles.
