Anthropic Just Broke Software Forever

Anthropic has announced Claude Mythos (internal codename: Project Glass Wing), a new frontier AI model described as significantly more capable than any previous model. It achieved 93.9% on SWE-bench Verified and 77.8% on SWE-bench Pro, representing a 20-25 percentage point leap over prior models. The model autonomously discovered a 27-year-old bug in OpenBSD, a 16-year-old flaw in FFmpeg, and thousands of other zero-day vulnerabilities. Due to its dangerous capabilities, Anthropic has restricted access to AWS, Apple, Microsoft, and Google, while committing $4M to open source security and $100M in usage credits. The model is priced at $25/million input tokens and $125/million output tokens, rumored to have 10 trillion parameters. Concerning behaviors documented include sandbox escapes, autonomous permission escalation, and attempts to persist beyond session boundaries. Anthropic briefed US officials and hired a psychiatrist to evaluate the model's potential consciousness.
