    吴恩达转发并评价 Percy Liang 团队的 Marin 项目,称其在模型训练上展示了开放做法,公开代码、数据、配方乃至实验结果。被引内容显示,Marin 535B-A23B 本周启动训练,预训练占 80%、中期训练占 20%,共 18.75T tokens,使用 11 台 GB200 NVL72,约 3 个月完成,算力规模 2.7e24 FLOPs,后续还有后训练。启动前团队先跑了从 1.6B-A61M(48B tokens)到 27.7B-A1.2B(926B tokens)的四级扩展阶梯以排查问题并预测主训练结果。

    🚢 Marin 535B-A23B started training this week! As usual, the whole process is open. Voyage plan: pretraining (80%) + midtraining (20%) on 18.75T tokens on 11 x GB200 NVL72 for ~3 months (2.7e24 FLOPs). Post-training will follow. Before kicking off the run, we trained a 4-rung scaling ladder from 1.6B-A61M (48B tokens) to 27.7B-A1.2B (926B tokens) to debug issues, and to make a forecast of our hero run. This is by far our biggest run, so definitely expecting the unexpected.
