為何最先進 AI 模型的統治力從 1 年縮水至 7 週
epoch ai 數據顯示，模型霸主的統治時長從 gpt-4 的 12 個月降至中位數的 7 週，這標誌著競爭白熱化及新發布模型優勢的縮減。
research from epoch ai highlights a drastic reduction in the longevity of state-of-the-art ai models, with gpt-4 holding the top spot for about a year compared to the current median of just seven weeks. since february 2024, the lead position has changed hands 17 times, with openai's o1 holding the second-longest reign at only three months. this shift suggests the market has moved from a single dominant outlier to a cycle of rapid, iterative improvements where labs trade advantages quickly. it signals that building a sustainable moat around model capability is becoming increasingly difficult as labs release updates more frequently.
