SDXL-VAE-FP16-Fix

SDXL-VAE-FP16-Fix is the SDXL VAE, but modified to run in fp16 precision without generating NaNs.

Details

SDXL-VAE generates NaNs in fp16 because the internal activation values are too big:

SDXL-VAE-FP16-Fix was created by finetuning the SDXL-VAE to:

1. keep the final output the same, but

2. make the internal activation values smaller, by

3. scaling down weights and biases within the network

There are slight discrepancies between the output of SDXL-VAE-FP16-Fix and SDXL-VAE, but the decoded images should be close enough for most purposes.

Evaluation on COCO val-2017, 256x256, RandomCrop with padding
Metrics:
LPIPS:
https://github.com/richzhang/PerceptualSimilarity/ (lower better) and structural similarity index measure via skimage.metrics (higher better)
Metrics given as: mean [79% credibility interval]

描述:

Improved decoder weights

* Further-reduced risk of NaNs
* Further-reduced discrepancies with original SDXL-VAE (0.9) decoder

Encoder weights are unchanged.
