MiniMax H3

Repackaged model files for ComfyUI.

Original model repository:

• https://huggingface.co/MiniMaxAI/MiniMax-H3
• https://huggingface.co/lightx2v/Minimax-h3-Turbo

The Qwen3-VL-32B nvfp4_awq quant is converted from: https://huggingface.co/cybermotaz/Qwen3-VL-32B-Instruct-NVFP4

This nvfp4 text encoder does not require Blackwell GPU to use.

For diffusion models prefer int8_convrot if you are able to use pytorch with cu130.

fp8_scaled should only be used if you cannot use int8_convrot.

Embeddings

To use the embeddings in a text prompt, invoke them in the CLIPTextEncode node like this (you can omit the .pt extension): embedding:embedding_filename.pt.
