Kimi K3 2.8T is so large that it will not fit on a single NVIDIA DGX B200, even at FP4. A GB300 NVL72, B300, or MI355X system is required, as each GPU has 288 GB of memory.
One optimization that could make Kimi K3 fit on B200 is to gang multiple nodes together and use a technique called WideEP. The issue is that B200 has only 400 Gbit/s of bandwidth between nodes, whereas NVL72 has 18× higher inter-node bandwidth.
