AI 性能成本下降速度超过以往任何技术
原标题：AI performance costs are falling faster than those of any previous technology
AI 摘要
Epoch AI 研究显示，在特定 AI 基准上达到固定性能水平的成本自 2023 年以来以每季度约 47%、每年约 13 倍的速度下降，快于以往任何变革性技术。MIT 研究者基于 Artificial Analysis 数据得出年降幅为 5 至 10 倍，剔除硬件降价和竞争压力后，纯算法效率提升约为每年 3 倍。研究同时指出，新推理模型因消耗更多测试时算力，单次运行当前最强模型的成本反而可能更高，且基准分数提升并不总等于效率提升。

AI performance costs are falling faster than those of any previous technology The price of reaching a fixed performance level on select AI benchmarks has dropped sharply since 2023. Epoch AI, a research organization that tracks AI trends, says costs are falling by about 47 percent per quarter on average, or about 13x per year. No other transformative technology declined that fast, the group says. The number reflects market prices for a fixed benchmark score, though, not pure algorithmic or archi
