# Dean W. Ball：前沿模型发布数月即过时，行业陷入回本困境

Dean W. Ball 指出 AI 行业面临糟糕的商业动态：前沿模型训练成本极高，但只能在发布后的短短几个月内保持“前沿”地位并回收成本。一旦这个窗口期过去，随着新一代模型的发布，旧模型迅速沦为“次前沿”产品，投资回报周期被严重压缩。

## English Version

**Dean W. Ball: Frontier Models Become Obsolete Months After Release**

Dean W. Ball criticized the current economics of the AI industry, noting that frontier models are trained at enormous costs but have a limited shelf life. A significant fraction of the cost must be recouped in the few months immediately following release while the model is still considered state-of-the-art. Once that period elapses, older models quickly become obsolete, creating immense pressure on return on investment.
