AI Audio on Mobile CPU
Stability AI, renowned for its generative AI models in image, video, audio, and 3D, partnered with Arm to bring its text-to-audio AI model, Stable Audio Open, to mobile CPUs for the first time. This breakthrough, running on an Arm-based CPU, enables creators to generate audio, including sound effects entirely on-device, with no internet connectivity required.
By seamlessly leveraging the Arm software stack, including the Arm KleidiAI library, and distilling the Stable Audio Open model, Stability AI achieved remarkable AI performance optimizations and reduced response times by 30 times—from minutes to seconds.

Optimized for up to 30x faster model response

Offline on-device custom sound creation

Redefining GenAI Performance
A near-instantaneous user experience is also made possible because of the model distillation by Stability AI and Arm. Arm KleidiAI open-source library kernels are integrated into the ExecuTorch AI framework via the XNNPACK library and provide access to the latest AI features in the Arm architecture.
The faster model responses for generative AI on mobile CPU show how collaborating with Arm and developer enablement technologies such as KleidiAI can make previously unattainable AI applications, models, and workloads run smoothly on mobile.
