Kimi-K3 looks built for datacenters, not ultra-low-bit local quantization

The author argues that models like Kimi-K3 are built for datacenter deployment, not aggressive local quantization. In a quoted analysis, the claim is that a 1-bit or 2-bit version would not ship at usable quality, because the MXFP4 weights leave little “dead weight” to remove and the recipe still ends up around 4.36 BPW when fully constrained.

The practical takeaway is that if you want Kimi-K3-like behavior locally, the better path may be distillation rather than pushing quantization much further. The post frames full BF16 as the only way to match the published numbers closely.
