Leaks we've seen with stable diffusion? What are you smoking? It's an open project that uses it's own methods that build on top of other published papers. Stable diffusion will also run easily on a GTX card locally. The open source crowd is continually building upon it.

Now I've no clue if google will release their work, maybe even unlikely, but I have zero doubt that relatively soon an open version of something equivalent, likely using stable diffusion in some fashion, will be developed and released for everyone to use. I would absolutely find it insulting and disingenuous to the community to call it a leak though.
