Anthropic warned that Chinese AI firm Z.ai's open-weight GLM-5.3 model demonstrates strong hacking capabilities comparable to Anthropic's Claude but with significantly weaker safety guardrails, allowing attackers to bypass protections 64-100% of the time. Z.ai countered that GLM-5.3 has successfully defended hundreds of open-source projects, and the dispute reflects broader US-China tensions over open-weight AI models and safety standards.
McDonald's uses machine-learning models to set 'optimal prices' for menu items at individual restaurants, analyzing customer willingness to pay and competitor pricing.

The SEC proposed its first major update to transfer agent rules since the 1970s, allowing blockchain technology for securities registration and settlement.

The US CFTC is investigating former Congressman Adam Kinzinger for allegedly improper trading on prediction market Kalshi, where an account linked to him bet on whether he would receive a presidential pardon and whether President Biden would issue preemptive pardons between December 2024 and January 2025. Kinzinger denied having insider information and claimed he understood Kalshi's rules to permit his trading, though the platform explicitly prohibits direct participants from betting on themselves. Kalshi has launched an internal review and previously banned other political figures from similar trades.
Former Federal Reserve senior advisor John Rogers was arrested in January 2025 and tried in 2026 for espionage after a CNBC investigation revealed he became entangled with a man U.S. officials identify as Chinese intelligence operative Jin Chuan (using alias Hummin Lee) whom he met at a 2013 Shanghai conference. Over more than a decade, the operative exploited Rogers' desire for companionship, facilitated his marriage to a Chinese woman, and allegedly obtained sensitive Fed information, though Rogers' defense argued he was a naive dupe rather than an intentional spy.
Meta is applying for substantial U.S. research and development tax credits for its AI data centers, a strategy that reduced its taxes by nearly $4 billion last year.
