Anthropic's Mythos 5 ban: the futility of blocking one model in a multipolar world
the us government forced anthropic to take its advanced mythos 5 and fable 5 models offline over national security fears, but experts warn similar cyber-capabilities are inevitable across the industry.
anthropic took its claude fable 5 and mythos 5 models offline after the trump administration issued an export-control directive, fearing fable 5’s guardrails could be bypassed to access mythos’s vulnerability exploitation tools. despite anthropic’s attempts to release these capabilities safely through restricted previews like project glasswing, regulators deemed them a national security risk. security researchers tarah wheeler and bruce schneier warn that this focus on anthropic is myopic, as competitors like openai and open-source developers are on the verge of releasing equivalent models. the situation signals a shift where offensive cyber capabilities are becoming a standard feature of frontier models, rendering single-model bans ineffective.
