What it does
Minimax H3 is an agent skill from calesthio/OpenMontage. Generate MiniMax H3 (Hailuo 3.0) video through the official MiniMax v2 API, fal.ai, Runway, ComfyUI Partner Nodes, or local open weights in ComfyUI. Use for 4-15 second 2K clips, first/last-frame animation, and image/video/audio reference-conditioned video.
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Diffusion and image models. It works with MiniMax, ComfyUI and fal. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is AGPL-3.0.
When your agent uses it
- 4-15 second 2K clips
- First/last-frame animation
- Image/video/audio reference-conditioned video
Example prompts
- “/minimax-h3”
What it can do on your machine
Read from SKILL.md and the folder at commit 9327439. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Minimax H3 loads about 580 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 257 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Generate MiniMax H3 (Hailuo 3.0) video through the official MiniMax v2 API, fal.ai, Runway, ComfyUI Partner Nodes, or local open weights in ComfyUI. Use for 4-15 second 2K clips, first/last-frame animation, and image/video/audio reference-conditioned video.
MiniMax 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.
