v1 NVFP4: 2.8x faster, 44% of the size, vision tower held out
Verified signatureNVFP4 of Karti-Small-VL-4B v1. 51.8 tok/s against BF16's ~18 on a GB10, 3.7 GB against 8.5. 98 vision Linear modules held out and all 297 vision tensors left unquantized; gated on real images, not text canaries. Quality against BF16 is stated on the card: invented-identifier 0.048 vs 0.023, panel-reading 0.924 vs 0.967, both against an untrained base at 0.378 and 0.595.3dd82e6
