MiniMax H3-Image

MiniMax H3-Image is an image model in the MiniMax H3 series, designed for text-to-image generation, reference image generation, and image editing. MiniMax was introduced on November 11, 2026, highlighting its high-resolution output and the ability to use up to 16 reference images simultaneously. It is ideal for creators looking to explore product visuals, character scenes, and design concepts, and also provides developers with an API and an open-weight track.Official Introduction

Core Capabilities and Use Cases

• Multi-image editing:Including characters, objects, materials, and composition references in a single request is ideal for exploring product scenarios and creating visual series. Even when there are a large number of reference images, you should still check each one individually for the subject, proportions, and details.
• High-resolution output:The API supports custom width and height settings, with an output resolution of up to 20 million pixels; 4096×4096 is one of the square 4K specifications and should not be confused with the 4K definition for landscape-oriented video.
• Unified Creation and Editing:Text generation and editing with reference images use the same model series; the API also offers a "Highspeed" option, allowing you to choose based on your budget and desired wait time.

The API can generate 1 to 10 images at a time and supports JPEG, PNG, and WebP formats; it does not currently support transparent backgrounds, mask editing, or preview images. Therefore, for product assets with transparent backgrounds or retouching tasks that require precise mask control, you should first determine whether other tools are needed.API Capabilities and Limitations

How to Get Started

1. surname CongOfficial Product DescriptionLog in to MiniMax Code, or select the Image API on the MiniMax Open Platform. Account information and quotas for the web interface and API are subject to the respective entry points.
2. First, clearly specify the purpose, subject, aspect ratio, and details that must be retained. The editor should prepare reference images that are authorized for use and indicate the role each image plays.
3. Developers should use MiniMax-H3-Image in their requests; include 1 to 16 reference images in the request. Do not use both the “aspect ratio” and "area range" settings simultaneously.
4. After downloading the results, check that the text, logos, perspective, and objects are consistent. For product images in particular, verify the actual specifications; do not allow generated details to replace the actual product information.

Costs, Deployment, and Licensing

The API is billed based on tokens for input text, input images, and output images, rather than a fixed price per image. The official per-image text-to-image examples for the Standard plan are: approximately $0.02179 for 1K, approximately $0.02333 for 2K, and approximately $0.06879 for 4K (standard). Actual costs may vary depending on the prompt and prompt enhancements. Requests meeting the minimum requirement of 16.6 million pixels will receive a 50% discount on total request fees until 00:00 Beijing Time on November 18, 2026; the official 4K example costs approximately $0.03439. Highspeed pricing differs. Do not treat limited-time examples as permanent pricing.Official Billing Schedule

On-premises deployment is not a lightweight desktop application: The model files listed in the official model card total approximately 68.65 GB, and additional components—such as a text encoder—are required. Resources should be evaluated based on the inference framework and actual hardware configuration.Model Card and Deployment Instructions

Weight is licensed under a custom community license, which is not equivalent to unrestricted open source. The license excludes the European Union, the United Kingdom, South Korea, and the United States; users or their affiliates with annualized revenue exceeding $1 million, or those providing hosting services to third parties, must obtain additional written permission in advance. Deployment, distribution, and export use are also subject to the relevant terms.Full License

Comparison of Similar Tools

If your primary goal is high resolution and a large number of reference images, H3-Image is worth trying; if a transparent background is a key requirement, you should prioritize comparing solutions that support this capability. When making your selection, test the service using the same set of your own images to compare the cost of revisions and actual billing—this is more useful than simply looking at official speed claims.
