Use when writing or debugging prompts for MiniMax H3 (Hailuo 3) video-with-audio generation, running the open weights locally in ComfyUI, choosing a quant or an acceleration LoRA for the VRAM you have, wiring reference-to-video with images, video or audio, or when a generated clip produces gibberish speech, drifts off a reference identity, garbles audio after a latent upscale, or refuses to run on a build that looks current.

# MiniMax H3 (Hailuo 3)
H3 generates **video and synchronised stereo audio jointly**, from text, images, reference video, reference
audio, or any mix. It is the same model family whether you hit the hosted API or run the open weights, but the
two paths are wired completely differently and only one of them is free.
**Two paths, do not confuse them.**
- **Hosted API**, partner nodes `MinimaxHailuo03TextToVideoNode` / `...FirstLastFrameNode` / `...ReferenceNode`,
category `partner/video/MiniMax`. 2K output, priced per second, no local weights.
- **Local open weights**, core nodes `MiniMaxH3ImageToVideo` and `MiniMaxH3ReferenceToVideo` from
`comfy_extras/nodes_minimax_h3.py`. 768p, free, and everything below is about this path.
**Who owns what, so you open one file, not three.** THIS file owns the prompt format and the operating rules.
`reference.md` next to it owns weights, quant sizes, acceleration packs and their wiring. The MiniMax entry in
