MiniMax releases open-weight H3-Image model for 4K image generation
MiniMax says H3-Image can produce a 4096 by 4096 pixel image in less than 10 seconds and is available as open weights and through its API.
MiniMax released H3-Image, an image model with open weights built on its H3 model, on 11 November 2026, publishing the weights on Hugging Face. The model creates images from text prompts or from reference images, and it also edits images.
MiniMax says H3-Image produces a 4K image of 4096 by 4096 pixels in under 10 seconds, up to five times faster than mainstream rivals, and can work from as many as 16 reference images. It says that, among open-weight models, H3-Image follows prompts most closely.
The model can also be used on the MiniMax API Platform, in MiniMax Code and in Hailuo AI. MiniMax says it is priced at 50 to 70 percent of comparable services.
