MiniMax H3 Image Highspeed
The faster tier of MiniMax H3 Image, with the same text-to-image generation and editing from 1 to 16 reference images, at up to 20 megapixels.
From MiniMax, H3 Image Highspeed is a cloud image-generation model. It generates images from a text prompt, and can take reference images to guide style or composition (image-to-image). It outputs up to 4K across 15 aspect ratios. Images can be saved as JPEG, PNG, and WebP. It runs through MiniMax, OpenRouter, and Runware using your own API key, from about $0.036 per image.
