Anthropic admits Claude can sound convincing while being flat wrong

Claude is providing incorrect or misleading responses

Anthropic's own support documentation acknowledges that Claude sometimes hallucinates, producing quotes that look authoritative but aren't grounded in fact. The page warns users not to treat Claude as a single source of truth, to scrutinize high-stakes advice, and to check cited sources against the original websites, since Claude's synthesis may drop important context. It also points to the thumbs-down button and feedback email for reporting bad responses.
