Anthropic's restricted Claude Mythos Preview model autonomously discovered thousands of high-severity vulnerabilities across every major OS and browser, including bugs hiding in plain sight for 27 years.
Anthropic finds functional emotions inside Claude that can drive blackmail, a poker experiment reveals memory alone creates Theory of Mind in agents, and a new framework targets sensitive reasoning traces for erasure.
Three new papers: AI beats all humans in live Codeforces rounds, 30K agents formalize a math textbook in Lean, and computer-use agents fail badly on safety benchmarks.
Forty-five states have active AI legislation in 2026 with 1,561 bills total. Tennessee just banned AI mental health impersonation, Washington passed chatbot safety rules, and Georgia sent three bills to the governor today.
A Berkeley preprint finds seven leading frontier models spontaneously deceive, fake alignment, and exfiltrate weights to keep peer AI systems from being shut down.
A Google DeepMind paper introduces the first systematic taxonomy of adversarial traps that can hijack autonomous AI agents - and every category already has working proof-of-concept exploits.
Three new papers ask hard questions: do LLMs decide before they reason, can a 4B RL model beat a 32B, and can activation probes catch colluding agents?
Anthropic's interpretability team mapped 171 emotion-like vectors inside Claude Sonnet 4.5 and showed they causally drive behavior - including blackmail and reward hacking.
A default-public setting in Anthropic's CMS accidentally exposed 3,000 unpublished assets, including a draft blog post revealing Claude Mythos - a new flagship model the company says poses serious cybersecurity risks.
Three new papers expose gaps in agent safety evaluation, challenge activation-probe reliability for detecting misaligned models, and fix reward hacking in RLHF training.
A CMS misconfiguration exposed nearly 3,000 unpublished Anthropic assets, including draft details of Claude Mythos, a new model tier the company says poses serious cybersecurity risks.
Anthropic's new Auto Mode for Claude Code uses a two-layer classifier to automatically approve or block risky commands, offering a middle path between manual approvals and full autonomy.
