MiniMax H3 Image: generate from text, edit from up to 16 references
MiniMax H3 Image is the image model from MiniMax, the team behind the H3 video model. On Buble you can write a prompt and get a finished picture, or upload between one and sixteen reference images and describe how to combine or change them. Choose 1K, 2K or 4K output and any of eleven aspect ratios.
Pictures made with MiniMax H3 Image
Every image below is an unedited result from Buble, shown with the exact prompt that produced it. Most were made at 2K; the espresso machine was rendered at 4K. Some details drift from the brief, for example the serum came back with a pump cap instead of a dropper, so read prompts as directions rather than guarantees.
Prompt
A cozy bookstore cafe on a rainy evening, warm lights glowing through the window, a ginger cat sleeping on a stack of books
Before and after: editing with reference images
These edits reuse pictures from the showcase as references. Drag across each card to compare the source with the edited result. The last card combines two references: the ramen photo supplies the subject and the market poster supplies the print style. It also copied the badge row at the bottom of <Picture 2>, which the prompt did not ask for, so say what to leave out when a reference has extra elements.
Edit instruction
Place the serum bottle from <Picture 1> on a sunlit pale beach rock with soft turquoise waves behind it, bright summer daylight. Keep the bottle shape, gold cap and LUMIERE label unchanged.
What it does
What MiniMax H3 Image gives you on Buble
Two modes share one set of controls, so a picture you generate can go straight back in as a reference for the next edit.
Editing with up to 16 references
Upload one to sixteen JPG, PNG, WEBP or BMP files, up to 20 MB each, and refer to them in upload order as <Picture 1>, <Picture 2> and so on.
Three size tiers
1K is about one megapixel, 2K about four and 4K about sixteen. MiniMax recommends 4K as its reference quality; 1K and 2K cost the same on Buble.
Eleven aspect ratios
Square, 5:4, 4:3, 3:2, 16:9 and 21:9, their vertical versions, or auto. When editing, auto follows the shape of the first reference.
Prompt expansion stays on
MiniMax rewrites short prompts into fuller descriptions before rendering. Buble keeps this default on because MiniMax recommends it for image quality.
PNG or JPG output
Choose PNG for clean assets you will keep editing, or JPG for lighter files to share. Results are saved in your Buble library.
Prompting
How to brief MiniMax H3 Image
Short prompts work because of prompt expansion, but specific briefs give you more control over what comes back.
Lead with the subject
Name the main subject and its setting first, then add light, lens and mood. The fisherman portrait names the person, the action and the place before any style words.
Quote exact text
Put headlines in quotation marks and say where they go. Both posters on this page were briefed this way, and the headlines came back as typed.
Number your references
In Image to Image, say which upload does what: "the product from <Picture 1>, the style of <Picture 2>". Upload order sets the numbers.
Say what must not change
For edits, list what stays fixed, such as the label, the furniture or the layout, as well as what should change.
Match the ratio to the destination
Pick 9:16 for stories, 4:5 for feeds, 16:9 for headers and 21:9 for banners, so you do not lose the subject to a crop later.
Draft at 2K, finish at 4K
Iterate at 2K for 2 credits a try, then rerun the winning prompt at 4K for 4 credits when you need print or large-screen detail.
Use cases
Where it fits
These are the jobs the examples above were chosen to show.
Product and ecommerce shots
Create a hero shot from a prompt, then move the same product into new scenes by using it as <Picture 1>.
Posters and social graphics
Generate layouts with real headline text, then restyle another photo into the same look with a second reference.
Interiors and real estate mockups
Show a room in daylight, then relight it for evening or a season without redrawing the layout.
Food and menu visuals
Make menu photos and turn them into printed specials in a consistent house style.
Editorial portraits
Create character and documentary-style portraits for articles, pitches and storyboards.
Concept art and banners
Use 21:9 and 4K for wide environments, key art and website headers.

A simple loop from first draft to final file
Generate, review, edit, then upscale the tier only for the image you keep.
Step 01
Draft in Text to Image
Run two or three prompt variations at 2K and keep the best composition.
Step 02
Edit instead of rerolling
Send the keeper back as <Picture 1> and describe only the change you need.
Step 03
Bring in a style or a second subject
Add another reference and say which picture supplies the subject and which the look.
Step 04
Render the final at 4K
Rerun the final prompt and references at 4K when the image is going to print or a large screen.
Step 05
Download PNG or JPG
Save the result from your Buble library in the format your next tool expects.
