MiniMax H3 Prompt Generator (Portable)

A local desktop tool that generates properly formatted prompts for MiniMax Hailuo 3.0 (H3) video. Supports Reference-to-video + audio (RF2VA), Text-only, First frame, and First+Last frame modes. Runs completely offline after setup using your own Qwen GGUF model.

Features

• Dark UI with image drag-and-drop

• Live token streaming and cancel button

• Strict H3 template output

• Fully portable — no ComfyUI or system Python required

• Auto-opens the browser

Requirements

• Windows

• NVIDIA GPU with a recent driver (CUDA 13.x compatible recommended)

• A Qwen3.8-VL GGUF + matching mmproj file

Setup

1. Download and unzip the package.

2. Put your GGUF and mmproj files inside the models folder (or set the paths in the UI).

3. Double-click run.bat.

4. The browser opens automatically to http://localhost:7860.

Notes

• First load can take a minute while the model loads into VRAM.

• The tool does not include the model — you supply your own.

• GPU offload works if the CUDA wheel and runtime are present.
