Good eyes! We currently pipe text input to Stable Diffusion, Dall-E and Midjourney at the same time and continue with the most pleasing result. The (very small compared to what we want to achieve) content we currently have required hundreds of renderings and Midjourney came out as most pleasing nearly all of the times. From what's on the website only the Sherlock Holmes renderings have been produced using Stable Diffusion. Nothing published so far from Dall-E, which most of the times is showing us uncanny valley. In terms of preference: We are experimenting hard to achieve better results using Stable Diffusion.
