New York City is weighing independent validation requirements for AI models before they can be sold or deployed in the city. The proposed checks cover accuracy, bias, privacy, data provenance, and safety, with a $25,000 fine for each unvalidated sale or deployment. At a council hearing, former Anthropic researcher Jacob Coxon said kill switches are not enough.

Researchers found a sharp split between AI and human preferences after ranking all 6,617 ICML 2026 papers. AI systems favored perceived impact and generalization across settings, while human reviewers favored novelty. The models also agreed strongly with one another, but their rankings were sensitive to online hype.

Questions about ChatGPT’s role in a suicide case triggered backlash after an OpenAI publicist tried to move an interview past the topic.

The team says shielding is live with zk proofs and non-custodial private transfers for Bitcoin assets. They’ve also put up a 0.1 BTC bounty for anyone who can break the privacy system, which is a fairly direct invitation to be annoying on purpose.

ZachXBT says he posed as a client to infiltrate a Chinese organized-crime syndicate that laundered more than $1 billion across exploits for North Korea’s Lazarus Group. The intelligence helped trigger freezes tied to the February 2025 Bybit hack and supported on-chain attribution.
