MiniMax just released an image model that generates 16-megapixel images natively, with downloadable weights. H3-Image produces 4096×4096 images without an upscaler, using just six sampling steps. The same model handles generation and editing, with support for up to 16 reference images.
One particularly cool example: give it an illustrated fantasy map and it generates a first-person view from the position marked by an arrow, placing the waterfall, bridges and castle in the scene. You can try it through Hailuo or the API, or run it yourself with tools including ComfyUI and Diffusers. The weights use MiniMax's community license, and the full model needs substantial memory.
