MiniMax-Music3-GGUF

MiniMax-Music-3 GGUF Quantizations

This repository contains GGUF quantizations for the diffusion transformer / DiT backbone of MiniMax-Music3, a state-of-the-art text-to-music model capable of generating structured, full-length songs up to 5 minutes long at 32 kHz stereo.

These quantized weights enable running MiniMax-Music-3 locally inside ComfyUI using the ComfyUI-GGUF custom node with significantly lower VRAM requirements.

🧩 Required Companion Files

The GGUF files in this repository replace only the diffusion transformer (DiT). To generate music in ComfyUI, you will also need the text encoder and VAE models provided by Comfy-Org:

• Text Encoders: Comfy-Org/MiniMax-Music-3 Text Encoders
• VAE: Comfy-Org/MiniMax-Music-3 VAE

📂 ComfyUI File Placement

Place the downloaded files into their respective folders in your ComfyUI installation:

ComfyUI/
└── models/
    ├── diffusion_models/   (or models/unet/)
    │   └── MiniMax-Music3-Q8_0.gguf
    │

🚀 How to Use in ComfyUI

1. Install the ComfyUI-GGUF extension via ComfyUI Manager.
2. In your workflow:
   • Load the GGUF model using Unet Loader (GGUF).
   • Load the text encoder using the standard CLIP / Text Encoder loader.
   • Load the VAE using the standard VAE loader.
