Kimi K3’s tech report is sparse on hardware details, unlike K2.5’s training setup

A reply repeats the critique that the Kimi K3 tech report is sparse on hardware and training details.
- The earlier Kimi K2.5 report included specific training infrastructure: NVIDIA H800 clusters and 8 × 400 Gbps RoCE links.
- The K3 report is said to be much thinner on those details.
- As a result, it’s hard to judge the compute scale or how much each factor contributed to the claimed efficiency gain.
