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.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by calesthio on GitHub. Read the source before you install it.

Installation

Install the Minimax H3 AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/calesthio/OpenMontage/tree/main/.agents/skills/minimax-h3
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/calesthio/OpenMontage.git /tmp/OpenMontage
mkdir -p .claude/skills
cp -r /tmp/OpenMontage/.agents/skills/minimax-h3 .claude/skills/minimax-h3

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Minimax H3 in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Minimax H3 on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Minimax H3 is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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 adaptive without 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.

Frequently asked questions

What does the Minimax H3 AI skill do?

Why use Minimax H3 on TypingMind?

Because you install it once and use it with any model. Minimax H3 is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Minimax H3 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/calesthio/OpenMontage/tree/main/.agents/skills/minimax-h3. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Minimax H3?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Minimax H3?

As many as you like. As long as a model supports skills, you can use Minimax H3 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Minimax H3 AI skill free?

Yes. It is published on GitHub by calesthio under the AGPL-3.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
