What you can create with MiniMax H3 Image

Build a new scene from a prompt, combine details from several references, or describe a focused edit to an existing image.

Build a composition from a detailed Text to Image prompt

Describe where each element belongs and how it should interact with the rest of the scene. For a perfume campaign, place an amber bottle in front of a fold of translucent fabric, light it from the upper left, and leave space on the right for a headline. A brief like this gives H3 Image clear instructions for subject placement, depth, lighting, and layout.

Image to Image editing with a clear change request

An edit prompt should explain both the change and the parts to preserve. For an interior concept, ask to repaint only the back wall in muted blue while keeping the sofa, wooden furniture, plants, viewpoint, and window light. For a portrait, identify the outfit or setting to replace and the pose to keep. This is more useful than asking for a general improvement. Open the Image to Image workspace when your starting point is an existing photo or illustration rather than a blank scene.

Combine subjects, materials, and settings from different images

Give each image a distinct role in the same composition. In the fashion concept shown here, the portrait guides the subject, the fabric guides the clothing, the flower sets the accent color, and the coastal mood board guides the setting. Describe which details to carry over from each reference and how they should fit together.

Give each material a distinct look

Describe how materials respond to the same light. In the fantasy scene, a glowing orb can cast a soft glow on woven fabric and sharper highlights on engraved metal. A brief like this gives H3 Image specific cues for texture, shadows, and reflections.

How to prepare your MiniMax H3 Image prompt

Use the workspace to turn a rough idea into a concrete image brief in three steps.

  1. Describe the image you need

    Write the subject, action, and setting in plain language. Add the visual style, light direction, and material details that matter to the finished image. If you are editing an existing image, switch to Image to Image and state exactly what should change and what should stay. Put the most important requirements first so the brief has a clear priority.

  2. Choose the frame and output settings

    Match the aspect ratio to the final placement: square for a product tile, portrait for a cover, or landscape for a banner. Choose a 1K, 2K, or 4K size option and a JPEG, PNG, or WebP format. Think about the crop and any space needed for a heading before choosing a larger image size.

  3. Review the brief before generating

    Read the prompt as a checklist: subject, composition, lighting, style, and any details to preserve. Remove conflicting directions and decide which requirement matters most. For reference-based work, identify what each image contributes. The concept gallery can help you find a direction; adapt the wording to your own subject and intended use, then keep the brief ready in the workspace.

What sets MiniMax H3 Image apart

MiniMax designed H3 Image to render large images quickly while following detailed briefs and combining visual references.

MiniMax H3 Image 4K generation

H3 Image renders a full 4K image directly, without a separate upscale step. That gives a product visual or wide illustration enough detail to inspect textures and crop individual areas.

Blend up to 16 reference images

MiniMax’s image editing model can draw from several sources in one result. Use a model photo for the person, a garment photo for the outfit, and a location photo for the background to plan a single fashion image.

Complex prompts and spatial understanding

Specify object placement, camera perspective, lighting, and reflections within the same brief. MiniMax demonstrates how H3 Image can turn a flat map into a first-person game scene or lay out the parts and labels in an exploded product diagram.

Render lifelike textures and natural light

H3 Image focuses on subtle details such as skin texture, strands of fur, fabric weave, and highlights on worn metal. Those details help make portraits, clothing, and product surfaces look more natural.
