MiniMax H3-Image hands-on: strong editing, weak faces, resolution quirks in ComfyUI
MaterialWestern3016 · reddit · 2026-11-11
A Reddit user tested MiniMax H3-Image's T2I and editing via official ComfyUI workflows and the official prompting guide, compositing five references into one scene. Findings: T2I renders dogs and products fine but faces frequently break — 4MP unusable, the recommended 16MP worse, 8–12MP merely acceptable, background washes out below 12MP; overall not competitive with other T2I models. Editing impressed: usable at 16MP, placements and interactions worked first try, though face likeness lagged (Qwen2.1 does faces far better). The full multi-subject edit prompt, declaring per-subject preserve/change rules, is included and worth studying.
