I think in the world of ML, contributing that much compute should count as co-creation. There is a lot of code published by academia that just needs compute and data, but they don't receive it. Stability deserves credit for Doing the Thing. IP rights are another thing but that's a whole subtree of legal questions that society is barreling towards.
People have to remember, back in 2022-08, AI was still not a big thing. DALLE-2 was only released 2 months ago, and was just a quickly forgotten novelty.
Emad had to have funded the training of SD even before DALLE-2, investing the cash in exchange for branding rights to a free model.
Its obviously an extremely good bet in retrospect (RunwayML is probably bleeding with regret), giving stability herculean name recognition despite not having done any high profile research themselves. But when the bet was made, it was quite an insane bet requiring a lot of vision.
Naming rights on the model were no part of the compute grant, we give them incredibly freely and also support. Naming was suggested by the researchers in this case.
We don't just put out compute, but made sure to clear up everything from Stable Diffusion 2 onwards 100% trained by Robin and team: https://github.com/Stability-AI/stablediffusion
