What It Does
VAELoader loads an external VAE model file, replacing the default VAE that ships inside most checkpoint files. This is common when using SDXL checkpoints with a known-better VAE, or when the checkpoint was distributed without a VAE component.
The VAE determines the final pixel-level quality of decoded images. A better VAE can reduce artifacts, improve color accuracy, and produce sharper details from the same latent representation.
Inputs
vae_nameSTRINGVAE filename from the models/vae directory.
Outputs
VAEVAEThe loaded VAE model.
What Numonic Captures
- VAE filename
- Presence of external VAE (indicates override of checkpoint default)
Known Gaps
- VAE file hash
- Whether the VAE was fine-tuned or the original release
