AI Auditors Catch Agent Misbehavior But Flood Reviewers With False Alarms
A new study finds frontier AI models can catch nearly all reward hacking in agent logs, but false alarms pile up so fast at scale that human reviewers would drown in noise — getting 3,000 false warnings for every 2,000 real incidents.

Revolut Swaps Claude Code for Chinese GLM, Cuts Coding Costs 90%
Revolut has moved roughly 2,000 engineers from Anthropic's Claude Code and OpenAI's Codex to a self-hosted instance of GLM 5.3, an open-weight model from Beijing-based Z.ai, cutting AI-assisted coding costs by approximately 90%. David Abitbol, who leads AI operations and infrastructure at Revolut, shared the migration story at the AI Engineer conference in New York, detailing how the fintech tuned the model from a "terrible" out-of-box experience of 14-second latency down to 1.6 seconds. The move underscores a growing trend: well-funded engineering organizations are betting on self-hosted open-weight models over per-seat SaaS subscriptions for AI coding tools.
