Anthropic has crossed a line
In a Nutshell
Anthropic's Mythos model vastly outperforms Claude Opus 4.6 on benchmarks, with its Glasswing preview exposing thousands of day-zero vulnerabilities in systems like FreeBSD and FFmpeg, shared privately with tech giants to patch before public release. While enabling hackers to craft advanced exploits and phishing, it empowers defenders more through automated vulnerability scanning, log analysis, and best practices, ultimately automating cybersecurity to overcome human weaknesses like inconsistency and phishing susceptibility. Long-term, AI levels the playing field but favors "good guys" hardening systems, marking an exciting automation era without doomsday scenarios.

Mythos is the next model from Anthropic, standing head and shoulders above Opus 4.6 according to benchmarks. Some benchmarks jump by about 20%, going from 80% saturation to over 93%, others from 53% to 65%. This represents a step change similar to ChatGPT 3.5 to ChatGPT 4 or 4.5. Rumors indicate it's a 10 trillion parameter model, showing continued scaling. This progress means AI is not hitting a wall in net effect.
Glasswing is the Mythos preview version given early access to about 40 titans of industry like Microsoft and Oracle. It poses a strong cybersecurity risk, so Anthropic provides this access to allow big tech companies to catch up, patch vulnerabilities, and add safeguards before general availability.
AI has reached a point where it can help hackers write code and analyze code bases to find new vulnerabilities. Mythos found thousands of day zero exploits, not published, but vendors are contacted privately. Examples include a 27-year-old vulnerability in FreeBSD, a highly secure Unix operating system used on mainframes, and a 16-year-old exploit in FFmpeg, an audio-video codec driver used widely.
This is significant for information technology, cybersecurity, and national defense. Recent news reports suggest China launched a semi-automated botnet attack powered in part by Anthropic's Claude, though not personally verified.
