About the VAE

liquidn2vae_IG4 is an experimental saturation-tuned VAE for Ideogram 4-style workflows.

It may produce:

• stronger saturation

• warmer color response

• clearer colorful backgrounds

• richer anime-style colors

Known limitations

• line-art shadows may become pink or magenta

• photorealistic images may have unstable saturation

• neutral gray areas may become warmer than intended

This is an unofficial experimental workflow and not an official Ideogram, FLUX.2, Black Forest Labs, or Comfy-Org release.
