评论称中国主要大模型均在用 Blackwell 级芯片训练

Why we picked it

有人观察说国内头部模型的训练卡已经是英伟达 Blackwell 这一代了,也就是说管制没拦住。消息只有一张帖子、没有实锤,但如果你关心芯片出口管制到底有没有用,这条线索值得记下来去交叉验证。

一条 X 帖子引发讨论:主要中国大模型(中国头部模型厂商)的训练算力来自 Blackwell 级别芯片,即英伟达最新一代数据中心 GPU。Blackwell 是英伟达在 Hopper 之后推出的代际,B200/GB200 等型号是其代表产品,而美国出口管制在名义上限制这类芯片进入中国市场。帖子作者对此评价为 really bad,认为这一事实会影响外界对中国模型算力来源与出口管制实际效果的判断。

Body

该说法目前只是个人观察,帖子没有给出具体模型名、芯片型号或采购渠道等可核验细节。如果属实,意味着 Blackwell 级芯片已通过某种渠道被用于中国模型训练,出口管制政策的执行存在缺口;如果另有解释(例如云区域租赁、海外算力或此前库存),结论会完全不同。对关注中美算力博弈和 GPU 供应链的读者来说,这条信息值得当作待验证的线索看待。

really bad. all major Chinese models are being trained on Blackwell class chips
