Summary

An article about Claude Fable 5, which introduced Mythos-class capabilities as part of Project Glasswing—a partnership between Anthropic and major tech organizations aimed at finding and fixing internet infrastructure vulnerabilities. The article discusses how Claude Fable 5's hidden safeguards (throttling AI researchers) created a trust problem for Anthropic, as the tool's power to find vulnerabilities could also be exploited maliciously. The access was restricted to certain organizations due to dual-use concerns.

Mythos was introduced in April as part of Project Glasswing, a partnership among top-tier tech organizations and Anthropic formed to find and fix vulnerabilities in internet infrastructure.
It was restricted to only certain organizations because a tool that can find previously unknown vulnerabilities to fix them can also be used to find previously unknown vulnerabilities to exploit them.
Claude Fable 5 gave users access to Mythos-class power, but its hidden safeguards turned a safety feature into a trust problem for Anthropic.
