Researcher analysis shows humans still outperform AI agents in long-horizon reasoning and test-time adaptation

Researcher Qiuyang Mang's analysis shows humans maintain advantage over current AI agents in long-horizon decision-making and test-time adaptation, finding that agents plateau within 24 hours on a two-week coding task while top humans continue improving over the full period. The finding distinguishes human strength in sustained strategic adaptation from agent capability in short-horizon tactical execution.
