Native multi-reference models like MiniMax H3-Image may kill ControlNet spaghetti workflows
comptedemon · reddit · 2026-11-12
A Redditor argues ComfyUI workflows that cram multiple character references, a background layout and a style reference into one generation are nightmarish, and open-weight models should move toward native multi-image input instead of more megapixels. He cites MiniMax H3-Image's open-weights docs: up to 16 reference images per generation, each settable as layout, style or object reference; prompts truncate past 4096 tokens; a benchmark shows an exploded CAD diagram of a motorcycle with labeled, separated mechanical parts (accuracy unverified). He asks how the model routes 16 images natively without frying 24GB of VRAM, and solicits local testing reports.
