Chinese company MiniMax has released the image-generation AI “MiniMax-H3-Image.” Its key strength is the ability to generate 16-megapixel images at a practical speed.

MiniMax-H3-Image is an image-generation AI derived from the video-generation AI “MiniMax H3.” It supports both image generation and image editing, and its standout feature is the ability to generate high-resolution images at 16 million pixels. When using typical image-generation AI to produce a high-resolution image, the usual workflow is to first generate an image at a lower resolution than the target and then use an upscaler to create a high-resolution version. In contrast, MiniMax-H3-Image can directly generate 16-megapixel images at a practical speed.


Below are examples of photorealistic image generation.


An example generated in the style of concept art for a 3D game.


It can also generate images containing text.


Here is an example of image editing. The left side is the original image, and the right side is the image with a texture applied by MiniMax-H3-Image.


You can also input up to 16 reference images. Below is an example of generating an interior-design image by inputting images of a room and furniture.


An interesting use case that has also been published is “generating an image by specifying a location on a map.” First, input the following map image and specify the location with a red arrow.


The generated result is shown below. The surrounding terrain and buildings have been completed based on the map.


MiniMax-H3-Image has been released as an open-weight model on Hugging Face. It uses the “MiniMax-H3-Image COMMUNITY LICENSE AGREEMENT” license and can be used free of charge for personal use in Japan.

ComfyUI already supports MiniMax-H3-Image, and official ComfyUI workflows for image generation and image editing have also been released. Since the default resolution setting in the official workflow is 4 megapixels, if you want to see the full potential of MiniMax-H3-Image, it is recommended to change the setting to 16 megapixels.
