I think it's so interesting and positive that Stable Diffusion has come out and absolutely destroyed DALL-E as a product. What are the best examples of DALL-E being integrated into a product? Are there any at all?

This is like bitkeeper vs git all over again. DALL-E is the early innovator but stable diffusion is going to clean the table.

The people who first originated the clip guided diffusion approach (rivershavewings around this time last year) are now working for stable diffusion so it's somewhat arguable that dalle wasn't actually first (just first to make a user friendly saas for it).

OpenAI announced and released CLIP on GitHub on January 5, 2021: https://github.com/openai/CLIP

You need CLIP to have CLIP guided diffusion. So the current situation seems to trace back to OpenAI and the MIT-licensed code they released the day DALL-E was announced. I would love to be corrected if I've misunderstood the situation.
