In terms of image outputs, Stable Diffusion and DALL-E 2 are quite similar. DALL-E 2 is often better at complex prompts, while Stable Diffusion images are often more aesthetically pleasing. With just 890M parameters, the Stable Diffusion model is much smaller than DALL-E 2, but it still manages to give DALL-E 2 a run for its money, even outperforming DALL-E 2 for some types of prompts. Unlike DALL-E 2, the Stable Diffusion code and trained model is Open Source and available on GitHub for use by anyone.In short, the two image generation models are comparable, with minor differences in how closely their outputs match expected outcomes.
