MiniMax-H3 Remix

MiniMax-H3 Remix is a custom dual-model H3 remix checkpoint built for ComfyUI video generation.

It uses a hierarchical recombination workflow instead of naive weight averaging: the two H3 branches are reorganized at targeted response blocks, with key modulation layers such as AdaLN handled separately. The goal is to retain stable generation behavior while introducing stronger visual detail, dynamic expression, and refined stylistic response.

LoRA contributions used during remix creation are statically fused into the checkpoint. No corresponding external style LoRAs are required for normal inference.

Available variants

The INT8 ConvRot version is a quantized deployment variant of the same Remix design. For maximum fidelity, use BF16 when hardware allows.

Installation

1. Place the .safetensors file in:

   ComfyUI/models/diffusion_models/
   

2. Load it with ComfyUI-FeiHou-Easy-H3.

3. Use a MiniMax H3-compatible workflow.

Recommended starting settings

• Sampler: res_multistep
• Scheduler: simple
• Steps: 8-12
• Optional Turbo LoRA strength: 0.75

These are starting points rather than fixed requirements. Adjust according to resolution, motion intensity, reference-image strength, and your intended visual style.

Notes

• This is a remixed checkpoint, not an officially trained MiniMax H3 base release.
• Avoid stacking the same LoRAs that were already baked into this model; excessive strength may cause oversaturation, unstable motion, or distorted details.
• INT8 reduces memory use, but BF16 remains the preferred version for demanding quality evaluation.
• Please follow the original MiniMax H3 license and all applicable local laws when using or redistributing this model.
