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.
