MiniMax H3 Image: AI Image Generator & Editor Online
Bottom line
MiniMax H3 Image: 2K or 4K pictures and photo edits with accurate text, from 1 credit per image. Generate from text or edit an existing image with MiniMax H3 Image in one place. VdoBloom shows the credit cost for either mode before you confirm.
MiniMax H3 Image is MiniMax's image model. On VdoBloom it makes pictures from a text prompt and edits photos you upload, at 2K or 4K, in 11 shapes: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 4:5, 5:4, 21:9 and 9:21.
Pricing is per image: 1 credit at 2K and 3 at 4K from a text prompt. An edit with one photo costs the same, and each extra photo adds a little, up to 4 credits at 2K and 6 at 4K with 16 photos. Prompts can be up to 32,000 characters, so long, exact descriptions are fine.
In our tests on 11 November 2026 it spelled every phrase we put in quotes correctly, on signs, posters and labels, and an edit changed only what the instruction named. Images took 12 to 27 seconds. For editing, upload 1 to 16 images: one to change it, several to combine them.
