About minimax-h3
A skill for selecting and operating MiniMax H3 video-generation routes across direct, hosted gateway, Runway, and ComfyUI options. It documents route-specific model identifiers, inputs, and prompting guidance for production workflows.
Key features
- 01Five provider and ComfyUI routes
- 02Text-, image-, and reference-to-video
- 03Local ComfyUI open-weight setup
- 04Route-specific duration and resolution notes
- 05Prompting and audio guidance
Use cases
- 01Choosing a provider route for H3 video
- 02Generating video from text or visual references
- 03Running H3 locally through ComfyUI
- 04Preparing prompts with camera and audio direction

Details
From the project READMEMiniMax H3
MiniMax H3 is the Hailuo 3.0 family. The first-party API identifier is
MiniMax-H3; fal.ai exposes the family as hailuo-03, and Runway uses
hailuo3. Do not substitute one provider's identifier into another API.
Choose a route
| Route | Tool call | Execution |
|---|---|---|
| MiniMax direct | minimax_video, model: "MiniMax-H3" | Hosted first-party v2 API; global or mainland-China region |
| fal.ai | minimax_fal_video | Hosted gateway; T2V, I2V, reference-to-video |
| Runway | runway_video, model: "hailuo3" | Hosted; 768P or 2K, 5–15 seconds |
| ComfyUI Partner Node | comfyui_video, model_family: "minimax_h3_api" | Hosted and billed in Comfy credits |
| ComfyUI open weights | comfyui_video, model_family: "minimax_h3_local" | Local GPU with official workflow and model stack |
For local ComfyUI, export the official workflow in API format and pass
workflow_json or workflow_path plus output_node. OpenMontage reports the
required diffusion model, Qwen3-VL text encoder, video VAE, and audio VAE; it
does not silently download large weights.
Operations and prompting
- Text-to-video: concrete ratio; do not use
adaptivewithout visual input. - Image-to-video: provide a first frame.
- First/last-frame: provide both images and describe the motion between them.
- Reference-to-video: images, videos, and audio can be combined. Audio needs at least one visual reference.
Write prompts as subject + action + camera path + environment + lighting + audio intent. MiniMax responds well to explicit camera direction. Keep the requested motion achievable within 4–15 seconds and inspect native audio as carefully as the image track.
Provider differences
The direct MiniMax v2 route currently outputs 2K and supports 4–15 seconds. Runway's Hailuo 3.0 route supports 768P/2K and documents 5–15 seconds. Partner Nodes require network access and credits. Only the open-weight ComfyUI route is local/offline after all models are installed.
