At MWC 2023, Qualcomm was showing off its new AI chops, particularly the ability to run a local instance of Stable Diffusion 1.5 to generate an image on a phone offline. We went hands-on with it to see how fast and how well it works.
The model was running on an Android phone with a Snapdragon 8 Gen 2 chip, in airplane mode. You just input a prompt for a photo using natural language, and the offline AI image generator starts building the image from a blurry outline to a finished product. The entire process takes less than 15 seconds to generate a 512 x 512 image.
