对 AI 培训基础设施规划和技术挑战有参考价值核心解读
OpenAI 的 CFO 声称其下一项大规模训练运行将于 2026 年秋季在 Vera Rubin 集群上进行，但专家对此表示质疑。Rubin 的 NVL72 集群预计在此时尚未达到稳定性，软件栈也不够成熟以支持真正的大规模训练运行。该集群可能仅适用于生产推理和小规模训练实验。

ALERT: OpenAI's CFO claims their next big training run will happen in Fall 2026 on Vera Rubin but that doesn't add up. Rubin NVL72 clusters likely won't be stable enough by then, and the software stack won't be mature enough to support a true "big training run." Rubin may be ready for production inference and small-scale training experiments, but not frontier-scale training in Fall 2026.
