MiniMax H3

Repackaged model files for ComfyUI.

Original model repository:

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.

Place the files in the following folders:

Embeddings

To use the embeddings in a text prompt, invoke them in the CLIPTextEncode node by combining embedding: with the filename of the embedding like this for minimaxh3_art_is_explosion:

embedding:minimaxh3_art_is_explosion

Just exchange the minimaxh3_art_is_explosion part with the filename of the embedding you want to use.
