Anthropic Study Reveals AI Errors Are ‘Hot Chaos’ Rather Than Goal‑Driven Misbehaviour

Anthropic researchers measured AI mistakes by separating systematic bias from random variance, finding that longer inference times and larger models increase chaotic behavior, that language models act as dynamic systems rather than optimizers, and that AI risk should be managed as complex‑system failure rather than malicious intent.
