9 April 2026 – The QVAC team at Tether today announced the release of QVAC SDK, a revolutionary open-source cross-platform Software Development Kit aimed at becoming a universal building block for Artificial Intelligence. This launch comes at a time when the world is on the brink of the “Stable Intelligence Era,” with a projected population of 10 billion humans coexisting with 10 billion autonomous machines and a trillion AI agents.
At Tether, we are laying the groundwork for the next phase of computing. We view AI as a fundamental element akin to the periodic table, a raw material that can be integrated into the very essence of our universe. QVAC serves as the atomic unit in this new reality, a modular, highly efficient, local-first AI platform designed to operate seamlessly across all devices, platforms, and operating systems, from industrial servers to microchips in everyday appliances. Our approach to AI is akin to a sophisticated interlocking intelligence system: standardized, stackable, and infinitely scalable. With the limitations of edge AI rapidly diminishing, QVAC stands out as the first intelligence framework capable of evolving alongside silicon, adapting to the future for generations to come.
The QVAC SDK represents a unified software development kit empowering developers to create, run, and optimize AI directly on any device, ensuring consistency across environments. This vision challenges the notion that intelligence should be a rented service, advocating instead for ownership by end-users. This groundbreaking framework enables the execution of intelligence tools such as LLMs and other popular AI constructs at scale on consumer devices, offering a seamless experience across iOS, Android, Windows, macOS, and Linux. This paradigm shift heralds a new era of 100% private and personal intelligence.
For end-users, the QVAC SDK means that AI functionalities, ranging from writing assistance to image generation, can operate instantly on their devices without relying on remote servers. Applications powered by QVAC continue to function even in low-connectivity scenarios, enhancing the practicality of AI in real-world applications. In the event of internet disruptions or server outages, the AI remains operational, ensuring uninterrupted user experience.
For developers, the SDK simplifies the development and deployment of local AI across various platforms, enabling teams to launch once and deliver a consistent user experience everywhere. By eliminating the need for separate implementations for different operating systems or heavy reliance on cloud APIs, developers can focus on creating products that are faster, more personalized, and resilient.
Central to the SDK is a unified abstraction layer encompassing multiple local inference engines. Built on QVAC Fabric and integrating leading local engines such as whisper.cpp and Parakeet, the SDK offers broad compatibility with the llama.cpp model ecosystem for various workloads. Developers can seamlessly leverage these engines through a unified API, facilitating the integration and interchangeability of capabilities without altering application logic.
Paolo Ardoino, CEO of Tether, remarked, “As the world hurtles towards a future where billions of humans coexist with autonomous machines and AI agents, the current centralized model is unsustainable. QVAC is designed for the impending reality of the ‘Stable Intelligence Era,’ offering a decentralized and resilient foundation for the future.”
Peer-to-peer functionality is a key feature of the SDK, leveraging the Holepunch stack to enable decentralized model distribution and inference without reliance on centralized infrastructure. This approach ensures consistent peer-to-peer behavior across platforms, fostering robust local AI applications independent of centralized services.
Through a single interface, the QVAC SDK supports a growing array of capabilities, including text completion, vision, OCR, text-to-speech, translation, and more. Developers can access these functionalities without managing separate toolchains or platform-specific integrations. Tether is committed to expanding the open-source ecosystem of QVAC to encompass all essential functionalities, catering to diverse applications including robotics and brain-computer interfaces.
As AI increasingly permeates physical systems and everyday life, the limitations of centralized models in terms of latency and fragility present engineering challenges. The transition towards on-device intelligence signifies a shift in AI deployment trends, prioritizing speed, privacy, and control. Local AI tools like the QVAC SDK offer developers a new avenue for creating intelligent applications that cater to evolving consumer expectations.
