Your Galaxy S23 may be powerful enough to quickly generate AI images

Fast AI image generation is now possible on an Android phone. In a recent demo video, Qualcomm was able to generate a 512 x 512 pixel image of a cat wearing a harness using the AI ​​image generator Stable Diffusion version 1.5 on an Android phone. And the kicker is that it finishes in under 14.42 seconds, putting it pretty close to what PCs can do with the technology.

To achieve this, company engineers used a process called “quantization”. Without delving too deeply into the weeds here, they basically took the desktop version of Stable Diffusion, scaled it down and optimized it for mobile devices. According to Qualcomm, the process increases performance [while] Also [saving] power by thereby making the model “work more efficiently”[consuming] less memory bandwidth.”

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