What the Saga Over Anthropic’s Mythos Tells Us About the Cyber Risks From AI
The U.S. government has lifted foreign access restrictions on Anthropic’s Fable 5 and Mythos 5 artificial intelligence models following a two-week suspension. The curbs were initially imposed after researchers discovered a jailbreak vulnerability, though Anthropic noted that similar exploits could be replicated on smaller models. To address these security concerns, the company has implemented a new safety classifier designed to block the technique. This decision restores global distribution for the models, marking a shift in the regulatory oversight of high-level AI deployment.
