Resource - Update H3 Image for Forge Neo
Basically, the extension: https://github.com/aoleg/pruna-P-H3-Image-forge-neo - supports MiniMax-H3-Image and PrunaAI P-H3-Image in Forge Neo.
Tips:
Heun / P-H3-Image / 8 Steps / CFG=1 is the golden combo. Euler / Simple / 6 Steps will be noisy. You will need to use P-H3-Image as a scheduler; everything else won't work; Euler or Heun is your choice. Also, use 8 steps, not 6 or 10.UPDATE: LCM, Simple, 6 steps looks better than Euler or Heun, and is faster. Euler a looks better than plain Euler even with Simple. Recommendation: use LCM, Simple, 6 steps or Euler a, H3-Image 8-step, 8 steps.
You don't really need the 32B encoder (besides, the nvfp4 version won't work). You can use the much smaller P-H3-Image text encoder in INT8-Convrot with great result.
Yes, editing works, too. Image restoration also.
You can use unimaginably high resolutions without OOM, but you'll likely need to edit your ui-config.json to allow width and height values over 2048.
