Someone Built an Open-Source 'Theoretical Mythos' to Reverse-Engineer Anthropic's Most Dangerous AI

A notable development has hit the crypto markets. In brief OpenMythos is a from-scratch reconstruction of the Claude Mythos architecture, built only from public research papers and educated guesses. Claude Mythos is Anthropic's most powerful model, locked away in Project Glasswing because it autonomously found 271 Firefox vulnerabilities and 32-step network attacks.

The repo is theoretical scaffolding—code without trained weights. It mirrors a separate effort by Vidoc Security that reproduced Mythos's vulnerability findings using off-the-shelf models.

Crypto markets are watching this development closely as investors weigh its potential impact on prices.
