Developer notes

• The conversion notes describe a graft-preserving W4A8 pass over Minimax-h3_Singularity_ref2va_v1.3_pruned_bf16.safetensors.
• The workflow uses the MiniMax H3 long-video stack plus a low-step acceleration path.
• This is the same-day efficiency play, not a new art style drop.

Our notes

• This is the MiniMax item most worth testing on a local card if you want a leaner path than full bf16.
• It is still not cheap on an RTX 3070 with 8 GB VRAM, but it looks more practical than a plain full-size H3 pack.
• I would treat this as a serious candidate, not just a watch item.

Required custom nodes

• Smite79/MiniMax-H3-LongVideos
• current ComfyUI MiniMax-H3 support
• ComfyUI-MiniMax-H3-PDD-Acc for the acceleration path used in the workflow

Required models

• Minimax-h3_Singularity_ref2va_v1.3_pruned_w4a8_graft_preserving.safetensors
• MiniMax H3 video VAE
• MiniMax H3 audio VAE
• matching MiniMax H3 text encoder

Notes

• Best used as the leaner local comparison point against the official or full-size H3 templates.
