About this model
MiniMax H3 Image is MiniMax's image generation and editing model, with built-in prompt enhancement that expands short prompts into detailed instructions. The MiniMax H3 Image Edit Edit API takes a text instruction plus up to 16 reference images, so you can edit a single photo or combine several into one composition, and it keeps the aspect ratio of the first input image. Output is 1K, 2K or 4K as PNG, JPG or WEBP. Use MiniMax H3 Image text-to-image to generate from scratch, or compare the faster tier with MiniMax H3 Image Highspeed Edit.
