Building on yesterday's News coverage of Mythos's policy impact, Mozilla revealed that Anthropic's Mythos AI model discovered 271 Firefox security vulnerabilities over two months with 'almost no false positives.' The breakthrough was attributed to model improvements and engineering integration, providing concrete evidence of AI's effectiveness in automated vulnerability detection.

First spotted on Reddit, now making mainstream headlines, Zyphra released ZAYA1-8B, a Mixture of Experts model with only 760M active parameters that outperforms models many times its size. It surpasses Claude 4.5 Sonnet and GPT-5-High on HMMT'25 math benchmarks (89.6 vs 88.3) using a novel test-time compute method called Markovian RSA, trained entirely on AMD hardware.
