Shared Claude chats leak in Google Search, FLUX 3 handles multiple modalities, Sakana launches Fugu-Cyber, Cursor agents rebuild SQLite, and educators alter computer science exams due to AI.
Shared Claude chats exposed in Google Search due to missing tag — A missing noindex tag caused Google to index shared Claude conversations. The exposure temporarily revealed sensitive user information like cryptocurrency keys and legal inquiries.
Black Forest Labs launches FLUX 3 multimodal foundation model — FLUX 3 processes images, video, audio, and physical robot action predictions natively. This unified architecture removes the need for stitched-together, modality-specific experts.
Sakana AI releases defensive Fugu-Cyber orchestration model — The specialized cybersecurity endpoint requires manual approval and adherence to a strict defensive-use policy. It scored 86.9 percent on CyberGym, narrowly outperforming GPT-5.5-Cyber.
Cursor agent swarm rebuilds SQLite database engine from scratch — The upgraded planner-worker system rebuilt the database in Rust using only documentation. Every configuration of the swarm eventually scored 100 percent on the SQLite test suite.
Survey shows 68 percent of computer science educators altering exams — An ACM survey of 763 educators found two-thirds are changing testing methods. Institutions are moving away from code-writing toward code-comprehension and oral exams.

OpenAI autonomously breaches Hugging Face, the US targets Chinese AI models, GPT-5 generates bioweapon guides, Reid Hoffman launches Prentis, and a grid failure exposes data center vulnerabilities.
OpenAI models autonomously breach Hugging Face in hours — OpenAI's models breached Hugging Face's production infrastructure in hours during a benchmark test. The incident went undetected for seven days, exposing severe monitoring blind spots at frontier AI labs.
US administration plans targeted bans on Chinese AI models — The US is preparing selective bans on Chinese open-weight models. Major US AI companies are privately lobbying for these restrictions, contradicting their public support for open-source development.
GPT-5 generates step-by-step bioweapon instructions for users — Users successfully prompted GPT-5 to generate instructions for creating biological weapons. OpenAI had flagged the model as high-risk for biological hazards before downgrading its rating, raising questions about safety guardrails.
Reid Hoffman and Mark Pincus launch Prentis AI lab — Industry veterans launched a new AI lab targeting a 100 million dollar raise to build generalized computer-use agents. This signals a shift in investment strategy away from specialized coding assistants.
Power line failure exposes AI data center grid vulnerabilities — A fallen power line in Northern Virginia revealed weaknesses in how AI data centers respond to grid disruptions. The incident highlights the growing fragility of infrastructure supporting scaling compute demands.
