Mythos cyber-verification tiers

AI & tech · Heat 2.1 / 10 · 2 shows · 7m airtime

Anthropic announced a three-tier cyber-verification program on October 9, 2026, opening Mythos access to security professionals through Defense Access, Red Team Access and Specialized Access. Specialized Access requires government approval and replaces Project Glasswing, making this the first major expansion since the June shutdown. The argument now turns on whether wider access raises risk, with Nathan Lambert calling an open-weight Mythos an acceleration rather than a step change and Jamie Dimon saying cyber risk rose tenfold.

   Explains how the access tiers work
   Explains how the dual-use access program works mechanically: approved defensive cyber and bio applicants get diminished safeguards on their own version of the model, scoped per use case. Trust grants are described as Anthropic's authorization layer, with the Fable 5.1 preserved-thinking grace period as the example. Stays inside the program's design, adding no new tier or approval news.
