OpenAI 智慧體在 AtCoder 總決賽中碾壓頂尖人類程式員
一個 openai 模型在 atcoder 世界巡迴賽總決賽中解決了全部五個問題，擊敗了所有人類競爭對手。這一勝利標誌著 ai 在複雜算法挑戰上的推理能力實現了飛躍。
openai's system claimed first place at the atcoder world tour finals 2026, solving all five problems in the algorithm division while the top human finished with just two. the model, which uses a small harness to scale compute, resembles the upcoming gpt-5.6 and successfully solved problems rated significantly harder than typical competition challenges. this victory follows a year of rapid advancement, climbing from the 49th percentile at the ioi in 2024 to the 98th percentile in 2025. the result signals that ai models are increasingly capable of outperforming elite humans in tasks requiring deep logical reasoning and problem-solving without specific competition training.
