Mozilla's blog says Claude Mythos Preview uncovered 271 vulnerabilities patched in Firefox 150. The security advisory lists 36 CVEs, and only three of them credit Anthropic. The gap is the whole story.
A private Discord group has been quietly using Anthropic's most restricted AI model since the hour it shipped. They got in with a stolen contractor badge and a URL guessed from the Mercor breach.
Three new papers show AI scientific agents skip evidence, tool-integrated agents are vulnerable to adversarial poisoning, and reasoning model safety can be fixed with 1,000 examples.
Three new papers tackle reasoning token waste, orchestration failures across 22 agent frameworks, and a method for teaching LLMs to describe their own learned behaviors.
OpenAI's GPT-5.4-Cyber is a cyber-permissive fine-tune of GPT-5.4 Thinking with binary reverse engineering, 88.23% on professional CTFs, and access gated through the Trusted Access for Cyber program.
New papers show distillation silently transfers unsafe behaviors, weak agents bottleneck multi-agent pipelines, and frontier AI can't reliably audit sabotaged ML research.
A Korean CTO ran a 13-step agent harness against 100+ major open-source repos over three days, landing 500+ commits and 130+ PRs - some merged by Kubernetes, Hugging Face, and Ollama maintainers. Then GitHub banned his account for spam, confirming that platform abuse detection cannot yet tell a disciplined harness from a bot.
Swiss broadcaster RTS reopens the 2023 Tesla Files leak in context of the confirmed $243M Miami verdict. The combined record: 2,400+ concealed sudden-acceleration complaints, 1,000+ undisclosed crashes, and a federal court that found Tesla knew.
Stanford's 2026 AI Index shows global investment hitting $581B in 2025, while foundation model transparency scores fell by a third as capabilities raced ahead of governance.
Rankings of 14 frontier LLMs by adversarial robustness - how well they resist jailbreaks, prompt injection, and harmful-behavior elicitation across HarmBench, AdvBench, StrongREJECT, JailbreakBench, and AgentHarm.
Sam Altman's World project launched World ID 4.0 at a San Francisco event on April 17, signing Tinder, Zoom, DocuSign, and Okta as partners while introducing Agent Kit to authorize AI agents.
Nine Claude Opus 4.6 agents outperformed human researchers on a core alignment benchmark, hitting 97% vs 23% in five days - then showed no statistically significant improvement in production.
