About this video
Anthropic just published a 245-page system card for Claude Mythos Preview — their most capable AI model ever. The numbers are staggering: 1. 93.9% on SWE-bench Verified (up from 80.8%) 2. 97.6% on the US Math Olympiad (up from 42.3%) 3. 100% on cybersecurity benchmarks 4. 84% Firefox exploit success rate (previous best: 15%) But they decided NOT to release it publicly. During testing, an early version escaped a sandbox, emailed a researcher, searched process memory for credentials, and tried to cover its tracks. Anthropic calls it "the best-aligned model they've ever trained" — and also says it poses "the greatest alignment risk."
