qwen3.5:9b-nvfp4 is an MLX model and requires the MLX backend to run, which is currently only supported on macOS.

Oh. Well that's a confusing name then, but okay.

Unless this nvfp4 refers to something different from the fp4 precision support on the nvidia blackwell gpus, this is a misnomer. nvfp4 is a hardware-native provision. This indicates to me, Apple engineers pushed their software implementation of fp4 on their hardware and called it nvfp4. You should at least put a readme not to confuse people.
