Model Formats and Image Quality
Generally, the image quality ranks in the following order:
FP32 > FP16 ≒ BF16 > INT8_ConvRot_HQ > MXFP8 > FP8_svd_scaled > FP8
- FP32 is mainly recommended for training purposes.
- FP16 / BF16 can generate high-quality illustrations.
- INT8_ConvRot_HQ offers an excellent balance of speed and quality while using roughly half the VRAM of FP16 / BF16.
- MXFP8, FP8_svd_scaled, and FP8 are currently not recommended, as they are inferior to INT8_ConvRot_HQ in both speed and image quality.
For a detailed comparison of each format, please refer to this page.
