Anthropic Reveals Testers Called Its Mythos Model a 'Super Weapon'

Anthropic CEO Dario Amodei disclosed that companies testing the firm's frontier model Mythos warned it was a "super weapon" and argued that using it should require a "gun license." Mythos, unveiled around April 7, 2026, is Anthropic's general-purpose large language model positioned in a tier above the Opus class of the Claude series. It was offered for limited testing as part of Project Glasswing, a cybersecurity-focused initiative, but a general release was withheld.
