Open-source alternative to Midjourney: image generation on your own hardware

Midjourney is bought for visuals: ads, social posts, covers. Open image models do the same work on your own machine or server: you can generate as much as you like, prompts and reference images never leave your side, and a model can be adapted to your style or product with a separate fine-tune. In exchange you take on the GPU, the interface setup and the search for good settings — a usable picture rarely comes out of the first prompt, it usually takes several iterations. Composition, hands and text inside the image are still uneven in open models, so part of the output has to be discarded or retouched. The one thing to check before you start is the license of the exact version: within a single family it can be either permissive or strictly non-commercial.
