Model Format and Quality
Generally, model size and image quality are proportional.
FP32 > FP16 ≒ BF16 > INT8_ConvRot_HQ > MXFP8 > FP8_scaled > NVFP4 > FP8
If you prioritize image quality, please use the FP16 / BF16 format.
Model_Quantization_MAE_and_SSIM_Similarity_new
vs_FP32 MAE_Similarity SSIM_Similarity Size FP32 100% 100% 35.2 GB FP16 92.7 % 87.6 % 17.6 GB BF16 92.6 % 87.5 % 17.6 GB MXFP8 92.0 % 83.8 % 10.3 GB FP8_scaled 91.6 % 84.8 % 10.1 GB FP8 85.8 % 59.1 % 8.8 GB NVFP4 87.2 % 71.9 % 6.8 GB INT8_ConvRot_HQ 92.6 % 88.6 % 10.6 GB
If you need speed or short on VRAM, choose INT8_ConvRot_HQ .
MXFP8, FP8_scaled, and NVFP4 are currently not recommended, as they are inferior to INT8_ConvRot_HQ in both quality and speed.
