Not tired yet, because for the first time since GPT-2, we're talking about a thing I can actually play with along with everyone else, instead of just reading about the fun people with the right connections and enough spare $$$ are having.

Well, you could play with Stable Diffusion, too. Moreover, you could install it on your computer - something that's unlikely to happen with the offspring of the so called "Open" AI.

Not sure why this got downvoted, this is 100% correct. Stable Diffusion is far more open than ChatGPT.

UX matters. ChatGPT is: 1) register on OpenAI website, 2) have fun. Stable Diffusion? It's free and easy if I can figure out where to download the current model (and not some of the weaker, stripped down versions or alternatives), and have a GPU farm to run it on?

IIRC, SD was one of the two or three image generation models that were published in the span of several days. Back then I tried to get my hand on any of them, and found only waitlists, wishlists, and one or two "lite" versions that could not deliver anything close to the interesting results everyone with right access was showcasing and talking about.

Tweaking and installing new models will take some additional effort, but there has been a veritable explosion in freely available resources, eg. https://rentry.co/sdupdates3

Also it runs fine on mid-range consumer GPUs, just with limited batch sizes.
