I'm disappointed that the smallest model size is 21B parameters, which strongly restricts how it can be run on personal hardware. Most competitors have released a 3B/7B model for that purpose.
For self-hosting, it's smart that they targeted a 16GB VRAM config for it since that's the size of the most cost-effective server GPUs, but I suspect "native MXFP4 quantization" has quality caveats.
Native FP4 quantization means it requires half as many bytes as parameters, and will have next to zero quality loss (on the order of 0.1%) compared to using twice the VRAM and exponentially more expensive hardware. FP3 and below gets messier.
