I wonder what they do better than Stable diffusion to generate the images. It seems more responsive to prompts and able to generate higher quality results.
Stable Diffusion 1.5 is state of the art... Heck, its not even close. But you have to run your own instance and dive into the ridiculous number of tools/models the community has developed to take advantage of it.<p>Midjourney has a strong (and improving?) base model and probably automates the usage of some similar tools behind the scenes. So on the surface, it is indeed better.
