Mythos AI and Firefox 150: Separating vulnerability research facts from hype
By

Master baker tier. Every paragraph earns its place on the tray.
Summary
The article critically examines the hype around Anthropic's Mythos AI system and its supposed discovery of vulnerabilities in Firefox. It clarifies that the widely-cited "under $20,000" figure actually covered a large-scale search process with roughly a thousand scaffolded runs and several dozen findings, not a single devastating bug. The piece also analyzes Mozilla's response about fixing 271 vulnerabilities in Firefox 150, separating factual security improvements from exaggerated online claims about AI-assisted vulnerability research.
