Anthropic's Claude Mythos Preview, released April 8 to a limited consortium via Project Glasswing, is dominating today's policy conversation. Foreign Policy reports the model autonomously discovered and exploited zero-day vulnerabilities across every major OS and browser during testing — succeeding 181 times on Firefox exploits where Opus 4.6 managed only twice. Anthropic has no plans for general availability, but regulators and security firms are scrambling to reassess cyber resilience assumptions.
OpenAI confirmed a partial outage starting around 10:05 AM ET today, affecting ChatGPT conversations, Codex, voice mode, image generation, and the API platform.

Regulators across Asia are stepping up scrutiny of cybersecurity risks in their financial systems, with concern specifically linked to Anthropic's frontier Mythos-class capabilities.

xAI released Grok 4.3 in beta to SuperGrok and X Premium+ subscribers. The incremental update arrives as xAI continues integrating into the broader X ecosystem following the $250B SpaceX acquisition earlier this year.
