Overview
What is MiniMax H3 Image?
MiniMax H3 Image is the open-weights image model from the MiniMax-H3 family, released by MiniMax in November 2026. One model generates images from text and edits them, with up to 16 reference images in a single request.
It renders at about 16 megapixels natively (4096 x 4096 for a square image) with no upscaler, and follows long, complicated instructions closely. Mage runs it on its own GPUs, at 2K for fast drafts or 4K for full detail, and MiniMax H3 Image LoRAs work on top of it.
Samples
Made with MiniMax H3 Image
Generated on Mage with MiniMax H3 Image. A prompt under a sample is the exact prompt that made it.
An ultra-wide 21:9 landscape at 4K 
A ramen counter at night, steam and lantern light 
Documentary portraitPrompt: an elderly fisherman with a white beard mending a bright orange fishing net on a weathered wooden pier at dawn, coils of rope and wooden crates around him, mist over a calm harbor with moored boats behind, soft golden side light on his weathered hands and wool sweater, documentary photograph, 50mm lens, fine detail
Poster with exact textPrompt: a vintage travel poster in flat screen-print style: a red seaplane flying over a turquoise bay with limestone cliffs and a small white lighthouse, the headline "ISLAND HOPPING" in bold cream capital letters across the top, and the line "DAILY FLIGHTS FROM PORT AZURE" in small capitals along the bottom, limited palette of red, cream, turquoise and navy, subtle paper grain
Macro detailPrompt: a macro photograph of an iridescent green jewel beetle on a dew-covered fern leaf, each water droplet reflecting the forest, the beetle's shell showing tiny pits and metallic green and copper sheen, soft morning backlight, shallow depth of field with creamy green bokeh
Strengths
What MiniMax H3 Image does best
Best at
- Large, detailed images that hold up when you zoom in or print
- Photorealism: skin, fabric, food, and landscapes without the usual AI look
- Posters, signs, and menus with exact text
- Edits that combine many reference images, such as a room and every piece of furniture in it
- Long prompts with many specific instructions
Trade-offs
- No negative prompt, step count, or guidance scale: the model is distilled to six fixed steps
- 4K takes a few times longer than 2K, so draft at 2K
- It reads English prompts best: write the description in English
Prompt guide
How to prompt MiniMax H3 Image
Tips that work on this model. The prompts under the samples above are good places to start.
Tips
- Describe the whole image: subject, setting, composition, light, and style. MiniMax H3 Image rewards complete descriptions.
- Put the exact words in quotes: a headline reading "ISLAND HOPPING". Say where the text sits and how it looks.
- For an edit, say what to keep from each image first, then what changes, then describe the finished picture. Refer to uploads as image 1, image 2, ... or by @mention.
- Use 4K when the detail matters: macro shots, landscapes, and prints. Use 2K to try ideas quickly.
