# MiniMax H3

Repackaged model files for ComfyUI.

Original model repository:

- https://huggingface.co/MiniMaxAI/MiniMax-H3
- https://huggingface.co/lightx2v/Minimax-h3-Turbo
- https://huggingface.co/alibaba-pai/MiniMax-H3-Fun-Controlnet-Union
- https://huggingface.co/Kijai/MiniMax-H3-experimental

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 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.
