stable diffusion vs DALL E 2?

Stable diffusion has more custom models that others have made and is usually much cheaper if you're using an API.

I would suggest Evoke if you're building a stable diffusion app

Stable Diffusion and Dall-E are similar in terms of both are large models for image generation. The differences are just in their weights and what they have trained on. Stable Diffusion is open source though, so it allows more combinations and people to develop on top of it.

Been working on helping people run Stable Diffusion on their browser using cloud GPUs in one click if any interest: https://stablematic.com/
