Your Galaxy S23 is probably powerful enough to easily generate AI images

Rapid AI image creation is now possible on an Android phone. In a recent demo video, Qualcomm was able to create a 512 x 512-pixel image of a cat wearing armor using AI-image-generator Stable Diffusion version 1.5 on an Android phone. And the kicker is that it’s done in less than 14.42 seconds, which makes it close to what PCs can do with the technology.

To achieve this, the company’s engineers used a process called “quantization“. Without getting too deep into the weeds here, they’ve taken the desktop version of Stable Diffusion, shortened it, and optimized it for mobile devices. According to Qualcomm, the process “increases performance [while] ALSO [saving] power by allowing the model” to run more efficiently thus”[consuming] less memory bandwidth.”

It is not known exactly what mobile device was used in the demonstration. However, we do know that it is powered by the Snapdragon 8 Gen 2 Mobile Platform, the exact same chipset found in Samsung Galaxy S23. It is worth noting that some developers managed to install Stable Diffusion on Sony Xperia 5 II, but generating images on that phone takes an hour due to weaker hardware. The main takeaway from Qualcomm’s success is its speed and what it could mean for users down the line.
