# SDXL-VAE-FP16-Fix |
|
|
|
SDXL-VAE-FP16-Fix is the [SDXL VAE](https://huggingface.co/stabilityai/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. |
