Moonshot reportedly trained Kimi K3 on Nvidia chips, including Blackwell

A report highlighted in the post says Moonshot trained Kimi K3 on Nvidia chips, including Blackwell parts, despite export restrictions. The article cites several people familiar with the matter.

The screenshots add more detail: Kimi K3 is described as the world’s largest open-source model at 2.8 trillion parameters, and Moonshot is reportedly seeking more Blackwell access to prepare K4. Another screenshot says the model was trained partly in China and partly at a Thailand data center, reflecting the difficulty of moving pre-training data overseas. The same report also notes that Alibaba’s Qwen3.8-Max was trained on Nvidia chips, including Blackwell.
