990: Inside Mythos: Anthropic's Locked-Down Frontier Model
From Super Data Science: ML & AI Podcast with Jon Krohn by Jon Krohn

About this episode
Jon Krohn discusses Anthropic's advanced AI model, Claude Mythos Preview, and its implications for cybersecurity.
Anthropic has built a frontier AI model so capable at finding software vulnerabilities that it has decided not to release it to the general public. In this Five-Minute Friday, Jon Krohn breaks down Claude Mythos Preview, a general-purpose model whose hacking abilities emerged as a side effect of broad improvements in code understanding and reasoning. Find out how Mythos achieved a nearly 100x improvement over Opus 4.6 on Firefox exploit generation, why Mozilla patched 271 vulnerabilities in a single release using an early version of the model, and what Project Glasswing Anthropic’s gated industry consortium means for the future of cybersecurity. Jon also shares practical tips for securing the code you’re generating with AI tools. Additional materials: www.superdatascience.com/990 Interested in sponsoring a SuperDataScience Podcast episode?
