P-H3-Image: Text to Image
Pruna AI's few-step image model built on MiniMax-H3: write a plain-language request and a local prompt upsampler expands it into a detailed scene before an 8-step sample. Pick the aspect ratio and megapixel target on the Resolution Selector to move between square, 4:3, 16:9 and portrait canvases.
Minimum ComfyUI version: 0.44.0
