MiniMax H3 Image Highspeed
MiniMax H3 Image Highspeed is the faster version of H3 Image. Generate images from a prompt or edit one input image, at 1K to 4K, up to 10 images per run.
## Overview
MiniMax H3 Image Highspeed is the high-speed version of MiniMax H3 Image, with the same inputs and capabilities. Describe an image and it creates it, or give it one image and describe the change you want. Use it when you want results faster.
## What you can build
- Quick edits such as background swaps, recolors, seasonal and lighting changes
- Concept images, thumbnails and storyboards from a prompt
- Product shots and variations that keep the same subject
- Several versions of one prompt for A/B testing
## Inputs
- A prompt describing the image to create, or the change to make and what must stay the same (up to 4,096 characters; longer text is cut).
- An optional input image to edit (JPEG, PNG or WebP). Without one, the model generates from the prompt.
- An aspect ratio: auto, 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 21:9 or 9:21. With an input image, auto keeps its ratio; without one, auto uses 16:9.
- A resolution: 1K, 2K or 4K (about 1024×1024, 2048×2048 or 4096×4096 pixels, shaped to the aspect ratio).
- The number of images to generate, from 1 to 10.
- The output format: JPEG, PNG or WebP.
## Outputs
- One to ten images in the chosen format, at the chosen aspect ratio and resolution.
- With an input image, each output is an edited version of it.
## Recommended settings
- Say clearly what must stay the same in an edit.
- Keep the aspect ratio on auto for edits so the output is framed like your image.
- Use 1K or 2K while exploring, then 4K for the final image.
## Limitations
- One input image per run. For several input images or a custom width and height, use H3 Highspeed Image Advanced.
- No mask-based editing and no transparent backgrounds.
- The prompt may be rewritten into a more detailed description before generation.
- Small text, logos and fine details can drift; check the results.
## Safety & compliance
- MiniMax runs content safety checks and may block a request or an image.
- Only upload images you have the right to use, and get consent before editing photos of identifiable people.
