Epoch AI 数据：AI 成本每季度下降约 47%，快于历史上任何变革性技术
Epoch AI 给了组狠数字：同性能下 AI 成本每季降 47%，比当年电力便宜 54 倍的速度下滑，值得对比下自己行业的降本曲线。
Epoch AI 统计显示，在同等性能水平下，AI 成本自 2023 年以来以每季度约 47% 的速度下降。这一速度是 DNA 测序成本下降的 4 倍，比计算硬件快 6 倍，比锂电池快 18 倍，比 1973 年之前的电力快 54 倍。

on the scale of cosmic history, the declining price of intelligence might be one of the most profound things happening both ends of the universe’s timeline are empty of knowledge: - the big bang: low entropy, no complex structure - heat death: maximum entropy, no usable energy gradients everything we build happens on the slope between them but the universe is generally a poor converter of its free energy into anything constructive. most of its free energy just radiates away as heat or collapses into black holes life, brains and now AI models are structures that sit in the entropy flow and divert a portion of it through constructive paths, building and maintaining low-entropy structures (machines, cells, crystals, memories) increasingly cheaper intelligence diverts increasingly more of that gradient flow through knowledge-building structures, complex, self-maintaining, predictive structures, filling the window in which understanding exists Epoch AI @EpochAIResearch AI is getting cheaper more quickly than any other transformative tech in history. At a given level of performance, cost has fallen ~47%/quarter since 2023. That’s 4× faster than DNA sequencing, 6× faster than compute, 18× faster than lithium batteries, and (up to 1973) 54× faster than electricity. 🔗 View Quoted Tweet📊 10 ⚡
