About
MiniMax-H3 × Z-Image — spatial detail graft (comfy-native) The comfy-native cuts of the MiniMax-H3 × Z-Image graft: Z-Image's spatial-attention profile on H3's engine — richer sets and textures, same identity, no per-shot sharpening creep. Full story, demos and verification on the GGUF page. Load with the plain Load Diffusion Model node, ComfyUI 0.32+. Files are the pruned H3 builds with the graft baked in (zs05 = late-block gains, dose 0.5): - bf16 — the master (ref2va) - comfy-fp8 / fp8e5m2 — fp8 scaled - comfy-int8 / int8convrot — the fast pick on RTX 50 - comfy-w4a8 / w4a4 / nvfp4 — 4-bit family for 16 GB cards (w4a8 is the quality pick; nvfp4 is Blackwell-native, emulated elsewhere) - comfy-mxfp8 — 8-bit microscaling, Blackwell-specialized; little benefit on older architectures - fl2va and ref2va variants where both exist; picking rules are identical to stock H3 RTX 30/40: the GGUF repo is 4–8× faster than any 4-bit comfy-native arm on Ampere. Made by joeygambino. Questions: open a discussion — I answer.

Using it via the API
Once AxForge deploys minimax-h3-x-z-image-native for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (minimax-h3-x-z-image-native below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"minimax-h3-x-z-image-native","prompt":"a drone shot over a forest"}'

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
