Don’t buy the DGX Spark: NVFP4 Still Missing After 6 Months

This post was written in my own words, but AI assistance. I own two DGX Sparks myself, and the lack of NVFP4 has been a real pain in the ass. The reason the product made sense in the first place was the Blackwell + NVFP4 combo on a local AI machine with a proper NVIDIA software stack around it. Without that, Spark becomes much harder to justify, especially given the bandwidth limitations and the compromises that comes with it. The DGX Spark was presented like a finished, premium system where NVFP4 was supposed to work out of the box.
