# MiniMax-H3 INT8 ConvRot

[简体中文](README_CN.md)

Converted MiniMax-H3 weights for
[ComfyUI-RH-MiniMax-H3](https://github.com/RH-RunningHub/ComfyUI-RH-MiniMax-H3).
This repository is a complete ComfyUI bundle: INT8 ConvRot DiT / text-encoder
weights, merged VAEs, FL2VA / Ref2VA configs, and optional turbo LoRAs.

The same package is mirrored on
[ModelScope](https://modelscope.cn/models/Gluttony10/MiniMax-H3-INT8-CONVROT).
Download from **one** source. The full snapshot is about **99 GiB**; keep at
least **120 GiB** free.

```bash
cd /path/to/ComfyUI
python3 -m pip install -U huggingface_hub
hf download Gluttony10/MiniMax-H3-INT8-CONVROT \
  --local-dir ./models/MiniMax-H3-INT8-CONVROT
```

China users can use the ModelScope mirror:

```bash
cd /path/to/ComfyUI
python3 -m pip install -U modelscope
modelscope download --model Gluttony10/MiniMax-H3-INT8-CONVROT \
  --local_dir ./models/MiniMax-H3-INT8-CONVROT
```

Re-run the same command to resume or update an interrupted download. On a
high-bandwidth machine with at least 64 GiB RAM, prefix `hf download` with
`HF_XET_HIGH_PERFORMANCE=1`.

The plugin auto-detects this complete converted bundle. The legacy
`ComfyUI/models/MiniMax-H3` directory remains supported.

## Optional Turbo LoRA

Select one turbo LoRA in the model loader for fewer sampling steps. Leave the
LoRA empty to run the base converted weights.

| File | Typical use |
|---|---|
| `minimax_h3_fl2v_turbo_4step_v0.1.safetensors` | FL2VA / T2VA 4-step turbo |
| `minimax_h3_fl2v_turbo_4step_v1.0_768p_bf16.safetensors` | FL2VA / T2VA 4-step turbo for 768p |
| `minimax_h3_fl2v_turbo_8step_v1.0_bf16.safetensors` | FL2VA / T2VA 8-step turbo |
| `minimax_h3_ref2v_turbo_4step_v0.1_bf16.safetensors` | Ref2VA 4-step turbo |

## Plugin

Install [ComfyUI-RH-MiniMax-H3](https://github.com/RH-RunningHub/ComfyUI-RH-MiniMax-H3)
and use the nodes under `RunningHub/MiniMax H3`:

| Node | Purpose |
|---|---|
| `RHMiniMaxH3ModelLoader` | Load the FL2VA / Ref2VA DiT and optional LoRA |
| `RHMiniMaxH3TextEncoderLoader` | Load the Qwen3-VL text encoder |
| `RHMiniMaxH3VAELoader` | Load the video and audio VAEs |
| `RHMiniMaxH3VideoGen` | T2VA / FL2VA / V2A |
| `RHMiniMaxH3RefGen` | Ref2VA with ordered image, video, and audio references |
