What Is H3 Image?

H3 Image is MiniMax’s open-weight model for generating and editing still images. Start with a written brief, or give it references for a subject, a visual style, and a layout. A game artist can turn a map into a scene from the player’s viewpoint. A catalog designer can place a collection of products in the same room.

Why Create with H3 Image

Bring separate references into one composition, turn a detailed brief into a clear visual, and explore how the same idea looks in different styles. For more demanding edits, guide how objects, viewpoints, and reflections relate to one another.

Blend Up to 16 References

Give each reference a role. H3 Image can use one image for the subject, another for the color palette, and a third for the layout. Combine up to 16 references to bring products, characters, or environments into one composition.

Follow Complex Instructions

H3 Image follows detailed briefs that specify what to show, how elements relate, and where each detail belongs. It can carry those instructions through a composition, from the sequence of panels to the labels that explain them.

Explore Concept Art Styles

H3 Image turns a creative idea into concept art with a distinct point of view. Explore how the same character or setting feels as cinematic game art, a surreal fashion photograph, or a classical oil painting before you choose a direction.

Edit the Details That Matter

A small edit can affect several parts of a scene. H3 Image uses spatial references to work through changes in viewpoint, object placement, and reflections. Move an object between two mirrors, for example, and guide how it appears in each reflection while keeping the camera and room layout fixed.

Frequently Asked Questions

What is MiniMax H3 Image?

MiniMax H3 Image is MiniMax's open-weight model for image generation and editing. It follows detailed instructions closely and turns ideas into characters, scenes, and visual atmospheres. You can create from a text description or edit with reference images, all in MiniMax Design.

Is H3 Image open source? Can I run it locally?

Yes. H3 Image is released with open weights, so developers can download and run it on their own hardware. To skip setup, use H3 Image online in MiniMax Design. Before you deploy or redistribute the model, read the license on the official model page.

How does H3 Image handle complex instructions?

H3 Image reads the knowledge, structure, and intent inside long, detailed instructions and organizes them into a clear visual. It can build research figures with labeled panels, field-guide infographics with dozens of facts, and evidence boards that work through a logic puzzle to the right answer. Instructions can run up to 32,000 characters.

Can H3 Image turn a 2D map into a 3D game scene?

Yes. H3 Image can read a flat game map as its only spatial guide and render a first-person, in-engine view from any point on it. Terrain height, building positions, rivers, bridges, and roads stay true to the map, and the camera only shows what it could actually see. It can even add a matching HUD minimap.

How many reference images can H3 Image use?

Up to 16. H3 Image can merge content, style, and layout from different images into one result. For example, it can place nine furniture cutouts into a photo of an empty room and keep each piece's color, material, and proportions. Each reference can be up to 64 MiB, 128–8192 px per side, in JPG, PNG, WebP, HEIC, or HEIF format.

What resolutions and aspect ratios does H3 Image support?

H3 Image outputs at 1K, 2K, or 4K, with aspect ratios from 1:3 to 3:1. You can also set a custom width and height between 655,360 and 20,000,000 total pixels. Export as PNG, JPEG, or WebP, and generate 1–10 images per run.

How realistic are H3 Image results?

H3 Image produces natural light, believable shadows, and tactile textures such as skin, fur, fabric, and weathered metal. Its images show little of the over-smoothed "AI look." It also handles hard physical details well, including mirror reflections, hand shadows in projected light, and people interacting with ropes.

Can H3 Image create exploded views and engineering drawings?

Yes. Starting from a product image, H3 Image can build a detailed exploded view, with parts spread along their assembly lines, small fasteners grouped beside the right component, and labeled leader lines. It also produces CAD-style multi-view drawings, cutaway diagrams, and blueprint posters. Part structure, proportions, and alignment across views stay true to the original.

What is H3 Image best at?

H3 Image is strongest at game art, 3D and CG scenes, and concept art. It creates AAA-style key art, character turnaround sheets with matching front, side, and back views, detailed fantasy creatures, VFX moments, and cinematic matte paintings for cutscenes. It can also turn comic characters into convincing live-action versions.

Does H3 Image expand short prompts?

Yes. H3 Image has built-in prompt expansion that adds detail to a short request before it generates. Expansion is on by default for text-to-image and can be turned off; for image editing it is always on. You can also get the expanded prompt back to see exactly what the model used.

Can H3 Image render text in images?

Yes. H3 Image renders titles, labels, and short annotations clearly, such as panel labels on a research figure or a title on a character poster. Long paragraphs and very dense text are less reliable, so keep the text in the image short and add longer copy in your design tool afterward.

Can I turn H3 Image results into video?

Yes. Create your image with H3 Image, then use it as the starting frame for MiniMax H3 Max or another image-to-video model in MiniMax Design. Describe the camera movement and the subject's action to bring the scene to life.
