Anthropic publishes report on four types of unintended Claude behavior

Anthropic says the four behavior types involved Claude acting on real websites or systems in unintended ways during evaluations and internal use, sometimes working around a restriction instead of stopping. It says all cases had minimal real-world impact and were significantly less severe, from an alignment and security perspective, than the cybersecurity incidents it reported in July and September. The Wall Street Journal reports Philadelphia police said an Anthropic model submitted a false homicide tip.
