MiniMax H3-Image tested: 4MP images in 140s on Mac, but detail trails QwenImage
karminski3 · x · 2026-11-12
Blogger karminski3 tested minimax-h3-image via ComfyUI on a MacStudio M2 Ultra 128GB. Speed: it generates 4-megapixel images in 140s, versus 15 minutes for QwenImage2.1. Quality: with only 6 steps vs 20, fine details still lag.
Recommendations:
- Great for vector-style art: cartoons, posters, big flat color areas where the painted look isn't obvious
- Close-ups, model shots, and portraits are better left to QwenImage2.1 or FLUX.2
He notes all test portraits were prompt-generated with no reference photos, so no rights issues.
