MiniMax H3 (Hailuo) — local video
This skill teaches the local-weights MiniMax H3 path in ComfyUI. It is the
pilot for #1155 (Official vs Empirical sources) because MiniMax publishes a
real prompting guide. Cite that guide by URL. Do not copy it into this repo.
Two products, two cost models — pick one
They share a brand and must not be mixed.
| Path | Nodes | Cost | VRAM | When |
|---|---|---|---|---|
| Local weights (this skill) | MiniMaxH3ImageToVideo, MiniMaxH3ReferenceToVideo, EmptyMiniMaxH3LatentAV, MiniMaxH3SigmaShift, MiniMaxH3MemoryEfficientSageAttentionPatch |
Free after download | Yes — INT8 + turbo LoRA is the 8 GB story | User wants 4–15 s stereo clips on their GPU |
| Partner API | MinimaxHailuo03TextToVideoNode, MinimaxHailuo03FirstLastFrameNode, MinimaxHailuo03ReferenceNode, MinimaxTextToVideoNode, MinimaxImageToVideoNode, MinimaxHailuoVideoNode |
Paid per generation | None | User has a MiniMax / Hailuo API key and does not want local weights |
API nodes do not take MiniMaxH3SigmaShift or Sage-attention patches. Local
nodes do not spend API credits. If the user asked for Hailuo cloud, stop and
use the API nodes + their key; do not download 40 GB of weights.
