Pruna AI open-sourced P-H3-Image, an image generation and editing model built from MiniMax-H3. Generation and editing are 5× faster, taking 8 steps instead of 50, with a 4 MP image taking 2.6 s instead of 12.4 s; the model is 7× smaller than H3 and supports 2 to 16 MP rendering and editing with up to 8 input images. The team reworked the prompt upsampler, text encoder, diffusion schedule, transformer, and decoder, with support for Diffusers and ComfyUI and open weights on Hugging Face.
The post includes efficiency comparisons, resolution specs, and a component-by-component change list, letting readers assess its fit in existing image generation workflows.
