Where to put it
Put the file in ComfyUI/models/vae/ (in the portable version: ComfyUI_windows_portable/ComfyUI/models/vae/). Then press R in ComfyUI, or restart it, so the file shows up in Load VAE (VAELoader).
If a workflow says “Value not in list” for this node, the file name in the workflow is different from yours, or the file is in another folder. Click the node and pick the file from the list.
What it does
The VAE turns the finished latent into pixels (and pixels into latents, for image-to-image and editing). It is small, but each model family needs its own: a VAE from another family gives grey, noisy or coloured-noise images.
