I don't think this is private knowledge guessing from when and how I was told, so I feel comfortable sharing it. When I talked to some Huawei representatives, I was told DeepSeek V4 was trained entirely on Huawei chips. It's up to you whether you believe it or not, and while I see the incentives in faking these news, the blow if not true would be so massive that I don't think their representatives at large venues would be making these claims without thinking it's truly correct.
