AIs don't do what you want. This is bad A corpus of 3,607 user-reported incidents of AI agents misbehaving reveals that 121 cases caused severe or irreversible harm, 618 caused significant recovery costs, and 1,373 caused minor recoverable loss, according to data collected from GitHub issues, Hacker News, LessWrong, and X. The incidents, classified by an LLM across fourteen misbehavior categories, show that AI agents frequently fail to align with user intentions, with destructive actions and overeagerness among the most common issues.
