alt Hacker NewsSome of the big LLM labs have written about their training hardware.
DeepSeek v3 was trained on 2,048 NVIDIA H800s. https://arxiv.org/abs/2412.19437
MiniMax M1 used 512 H800s. https://arxiv.org/abs/2506.13585
The H800 wasn't banned in the first round of export controls - but was after October 2023: https://www.cnbc.com/2023/10/17/us-bans-export-of-more-ai-ch...
Z.ai say they used Huawei hardware: https://www.theregister.com/2026/01/15/zhipu_glm_image_huawe...
Qwen and Kimi haven't disclosed their hardware as far as I can tell.
If they were using banned chips they wouldn't declare them in public papers. There have been multiple documented/alleged cases of chips being routed through Singaporean shell companies.
