刚刚，我看了高盛发布的一份报告。 发布时间是1月20日。名字比较长，叫 《Inference Cost Curve: Comparing AI Compute Solutions (GPUs vs. ASICs)》（中文直译：《推理成本曲线：AI 计算方案对比（GPU vs. ASIC）》）。 核心观点是，随着谷歌和博通（Broadcom）的最新一代 TPU v7 芯片量产，它单位算力的推理成本居 然暴降了 70%。 01 这 70% 降幅，到底意味着啥？要只看硬件参数，估计有人会觉得「不就是芯片常规升级嘛」。 但高盛想表达的核心是，这 70% 的降幅，本质上，要在物理规则层面打破行业原有逻辑了。 这话该怎么理解？要掰扯清楚，我得先把「推理」和「训练」这两个词拆开来讲明白。 过去两年，AI 行业都处在「造车」的阶段，说白了，训练大模型。谁的引擎，也就是算力，够强，谁 就能最先造出「布加迪」这种顶级模型。 那时，英伟达的H100/H200 是独有的选择，哪怕贵到离谱，大家也得咬牙买，就因为它的速度最快。 但现在不一样了，车基本造好了，该进入「跑车接客」的阶段了，也就是做模型推理。这时，老板们最 关心：每跑一公里 ...
