Contents (10 sections)
MiniMax H3 Image is a new image model that makes and edits pictures at 2K or 4K, and it spelled every word we asked for correctly on the first try. On VdoBloom it costs 1 credit per image at 2K and 3 at 4K. H3 Image Highspeed is the same model tuned for speed: 5 credits at 2K and 12 at 4K. We tested both on 11 November 2026; every image below is a first take, not edited. Try them in the AI image generator or the AI photo editor.

Test 1: words on a sign
Prompt: “A hand-painted wooden shop sign that reads "BLOOM BAKERY" above a blue door, morning light, cobblestone street, photo.”
The sign reads exactly as asked, in a hand-painted style, with small ornaments the prompt did not mention. The door, the brick and the cobblestones all follow the prompt.
Test 2: editing that photo
We uploaded the image above to the photo editor and gave both models the same instruction.
Prompt: “Change the sign text to "OPEN LATE" and make it night with warm light from the window.”
Both kept the building, the door and the flower box in place and changed only what was asked: the words and the time of day. Highspeed made the letters glow; the standard model kept them painted. Neither is wrong, so run the one you prefer.
Test 3: a 4K poster with small labels
Prompt: “A botanical poster of a lemon tree branch with small labels, cream paper, fine ink and watercolour.”
The model wrote a title, a Latin name, four labels with pointer lines and a notes box, all legible. It also invented the wording of the notes, so read small text before you print a poster like this: one label says “petels” where it should say “petals”.
Test 4: a detailed illustration on Highspeed
Prompt: “An isometric cutaway of a tiny two-floor bookshop cafe, warm lamps, people reading, detailed illustration.”
Two floors, a staircase, a coffee counter with a chalkboard and readers at tables, all in one consistent view.
Test 5: tall images for phones

| 4K image | 3 credits | 12 credits |

Prompt tips from these tests
- Put words in quotes. Every quoted phrase came back spelled correctly.
- Say where the words go: on the sign, on the destination board, as the title.
- Expect extra text on posters. The model fills a poster with its own captions. If you want only your words, say “no other text”.
- Name the medium: photo, watercolour, isometric illustration, travel poster.
- For edits, say what changes and nothing else. Both models left the rest of the photo alone.
