The landscape of artificial intelligence is evolving rapidly, and one of the most significant advancements is the movement of generative AI models from cloud servers to local mobile hardware. Recently, Stability AI partnered with Arm, the renowned semiconductor and chip design company, to bring the Stable Audio Open model to mobile platforms powered by Arm processors. This collaboration marks a transformative step toward on-device AI experiences that are private, fast, and accessible without internet connectivity.
Stability AI, known for its open-source AI models and commitment to accessible artificial intelligence, has taken a bold step in making audio generation tools usable on mobile devices. By teaming up with Arm, whose chip architectures dominate the global smartphone and tablet market, the company aims to democratize creative audio tools for users on the go.
This partnership focuses on optimizing the Stable Audio Open model—a neural network capable of generating realistic audio content, such as music segments or sound effects from textual input—for Arm-based mobile devices. Essentially, what was once a computationally intensive task requiring cloud-based GPUs can now be performed directly on a smartphone, thanks to this collaborative engineering effort.
Previously, generative models like Stable Audio were limited to cloud environments due to their heavy resource requirements. Processing large neural networks typically necessitated powerful data centers with extensive computing power, which meant users had to upload prompts to servers, wait for results, and rely on stable internet connections.
With this new partnership, the landscape is changing. By optimizing the audio model to run efficiently on Armv9 CPUs, Stability AI is bringing the model closer to users, directly into their pockets. The model can now generate an 11-second audio sample in just 8 seconds, marking a dramatic 30x performance improvement over previous mobile attempts.
This leap in performance is made possible by multiple technical strategies:
Model distillation: A technique used to compress and streamline large machine learning models without significantly compromising their capabilities. It allows the Stable Audio model to retain core functionality while being lightweight enough to run on mobile devices.
Arm’s KleidiAI libraries: These provide tools and software-level enhancements that unlock the full potential of Arm-based CPUs for AI tasks. KleidiAI helps optimize compute pathways, enabling efficient real-time processing of neural network operations directly on-device.
The implications of this breakthrough are substantial. With Stable Audio now running on mobile, users no longer need an internet connection to generate audio from text prompts. This capability allows for offline audio generation, a highly desirable feature for both privacy-conscious users and those in areas with limited connectivity.
Artists, podcasters, game developers, and content creators can now use AI-generated audio as part of their creative workflow without the need to connect to external servers or worry about data privacy. Whether someone is on a train, in a remote location, or wants faster response times, this development enables new levels of convenience and accessibility.
Moreover, integrating generative audio into mobile platforms supports instant feedback loops. Rather than waiting for cloud rendering, creators can hear results almost immediately, adjust prompts, and iterate faster—all from the convenience of a handheld device.
While this announcement currently centers on audio generation, it is part of a larger initiative between the two companies. According to Stability AI, the goal is to adapt a suite of generative models, including those for image creation, video synthesis, and even 3D content, for use on mobile platforms through similar optimizations.
As Arm-based processors become increasingly powerful and more mobile hardware manufacturers include dedicated AI accelerators in their chipsets, these models can be integrated into everyday applications. In the near future, it’s conceivable that mobile users will be able to generate high-quality music, create artwork, or edit videos with AI—all without needing to send a single byte of data to the cloud.
One of the key benefits of this on-device approach is enhanced data privacy. Traditional cloud-based AI systems require users to upload input data (e.g., text prompts, images, or audio clips) to remote servers for processing. It not only introduces latency but also creates privacy concerns regarding how data is stored, used, or shared.
By shifting AI processing to the device itself, Stability AI and Arm eliminate the need for data transmission. It offers stronger data protection and aligns with a growing user preference for privacy-preserving technologies. It also makes generative AI more viable for industries like education, healthcare, or field journalism, where internet access may be restricted or confidentiality is essential.
At the time of writing, the mobile-optimized version of Stable Audio Open is not yet publicly available for download. However, Stability AI has indicated that it plans to integrate this technology into future consumer applications and devices. The company envisions a future where everyday apps—such as mobile music editors, social media platforms, and storytelling tools—are equipped with embedded AI capabilities that function entirely offline.
Developers and software companies may soon have the opportunity to embed these tools within their apps, further accelerating the adoption of generative AI in daily life. With Arm’s widespread reach in the smartphone market and Stability AI’s open model philosophy, the partnership sets the stage for mainstream AI accessibility.
The partnership between Stability AI and Arm marks a pivotal advancement in the evolution of mobile artificial intelligence. By bringing the Stable Audio Open model to Arm-powered devices, they have not only improved access to generative audio tools but also set a new benchmark for what on-device AI can achieve.
With reduced generation times, offline functionality, and broad potential for integration across creative apps, this development is a powerful example of how edge computing can reshape digital experiences.
