this is the part that gets me excited. I ship a ~2GB model to browsers and right now every fine-tune means users download the whole thing again. if the base sits in cache (I key mine by sha256) a mask is basically a free update. you'd have to version the base carefully though, since a mask only fits the exact checkpoint it was trained on. curious if it survives quantization. Q4_K blocks store a scale and a min, so an exact zero isn't always representable. does a deleted weight stay deleted after you quantize?
