Definitely agree with this, and I might be wrong but I wouldn't be surprised if StableDiffusion made them choose this release model, since SD being accessible to everyone created more hype than the highly-restricted release of DALLE-2

Still keep in mind that this is only temporary demo ("During the research preview, usage of ChatGPT is free" [0]), running language model inference of this size is expensive and the model will likely be put behind a paywall soon
