Anthropic President Daniela Amodei Breaks Silence on Mythos: Model Is 'Very Good at Cyber Warfare' as Company Races OpenAI to Public Markets

In her first extended public comments on Mythos, Anthropic President Daniela Amodei told Forbes the model is 'very good at cyber warfare,' offering the most direct characterization of its offensive capabilities yet from Anthropic leadership. The interview comes as Anthropic confidentially filed its IPO S-1 with the SEC at a $965 billion valuation on June 2, with the company explicitly attempting to beat OpenAI to public markets; analysts note that an Anthropic listing before OpenAI could dampen demand for its rival. Amodei's characterization contrasts with Anthropic's prior positioning of Mythos as purely defensive, and arrives as the EU cybersecurity agency ENISA and NATO have just been added to Project Glasswing.
