文 | 我们可能想错了 xAI 在 2026 年 1 月宣布完成 200 亿美元 Series E 融资，并强调将用于扩张数据中心与算力基础设施、 推进 Grok 模型与产品。 更信号化的细节是它把算力规模写进核心叙事，称其 Colossus I/II 在 2025 年底 已拥有超过一百万 H100 等效 GPU。 这类口径值得被当作行业风向看待，大模型竞争正在从以模型为中心转向以交付为中心，模型决定上 限，但底座与入口决定谁能把上限规模化、产品化并沉淀为现金流。 这句话不是说模型不重要，模型仍然决定上限，也是入场券。变化在于，训练与推理成本抬升、能力扩 散加速之后，模型领先越来越难单独锁定份额。平台战争里，底座给的是供给确定性与单位成本，入口 给的是持续调用与现金流闭环，交付给的是稳定性、合规与企业可用性。xAI 把 200 亿美元砸向数据中 心和算力底座，并把 H100 等效规模写进叙事，本质是在把竞争重心从模型参数推向交付能力。 模型赛强调谁更强，交付赛强调谁更能把强变成规模，推动重心迁移的不是一句判断，而是三条约束同 时变硬。 第一条是成本曲线。前沿能力的边际提升越来越昂贵，训练资本开支上升，推理成本 ...
