You stated, "State of the art for low end generative AI is still running on some sort of desktop class GPU with optimised models and getting not-so-great results. A phone can't do that."
The Qualcomm article states, "Read on to learn how Qualcomm AI Research performed full-stack AI optimizations using the Qualcomm AI Stack to deploy Stable Diffusion on an Android smartphone for the very first time. "
Ok I guess it depends what you think of state of the art as being. I was thinking in terms of the best option that is somewhat generally available, like the best thing I could do with tools and techniques available. Qualcomm's research is better, but at an earlier stage. Maybe that is state of the art! Not quite as useful as I was thinking about though.
