Required Models

Diffusion model
minimax_h3_image_pruned_int8_convrot.safetensors

Text encoder
qwen3vl_32b_minimax_h3_int8_convrot.safetensors

VAE
minimax_h3_image_vae_fp16.safetensors

Recommended Settings

• Steps: 6

• Sampler: Euler

• Scheduler: Simple

• CFG: 1

• Denoise: 1

How to Use

Text-to-Image: Leave the image inputs disconnected and enter your generation prompt.

Image Editing: Connect a source image to the first image input and describe the changes you want.

Multi-Reference: Connect multiple images and describe how they should be used in the prompt.

MiniMax H3 Image refers to connected images as <Picture 1>, <Picture 2>, and so on, following their input order.

The workflow contains usage notes and model information for easier setup.
