TechCrunch: Research says some Chinese frontier models show signs of Blackwell GPU training

TechCrunch reported that a new research effort led by former OpenAI researcher Will DePue found fingerprints of Blackwell GPU training in open weights from DeepSeek, Moonshot AI, MiniMax and Ant Group. The strongest signals were seen in Moonshot’s Kimi K3 releases and DeepSeek’s V4 models, though the findings do not prove the models were trained entirely on Nvidia chips or that export laws were broken. The report also said Jensen Huang left Nvidia this week amid a scandal involving Megaspeed and possible export-control liability.
