In brief Tether has launched QVAC SDK, an open-source software development kit for running AI applications locally on devices.
The cross-platform toolkit supports text generation, speech processing, translation, and vision capabilities.
CEO Paolo Ardoino positioned the move as preparation for a world with “billions of autonomous machines and trillions of AI agents.”
Tether, the company behind the world’s largest stablecoin, USDT, announced the launch of QVAC SDK—a fully open-source software development kit designed to run artificial intelligence applications directly on any device without requiring cloud servers.
The cross-platform toolkit works unchanged across iOS, Android, Windows, macOS, and Linux environments, the company said. The SDK is built on QVAC Fabric, a fork of llama.cpp, providing compatibility with the llama.cpp model ecosystem for text generation, embeddings, and multimodal workloads.
Through a single interface, developers can access text completion, embeddings, vision, optical character recognition, text-to-speech, speech-to-text, and translation capabilities. The toolkit’s peer-to-peer functionality, powered by the Holepunch stack, enables decentralized model distribution and delegated inference. The company plans to add peer-to-peer swarms for decentralized training, fine-tuning, and inference in future updates.
“The world is approaching a moment where billions of humans share the planet with billions of autonomous machines and trillions of AI agents,” Tether CEO Paolo Ardoino said, in a statement. “The current model, routing every decision through a centralized server, won’t scale to meet that reality.”
“The laws of physics alone make centralized AI a dead end: speed-of-light latency, single points of failure, and concentration of control are features of a system designed for a smaller world,” he added. “QVAC is built for the world that’s coming. It is the building block of the Stable Intelligence Era.”
The SDK emerges from QVAC, Tether Data’s AI research initiative focused on building open, decentralized, and adaptive intelligence systems. The company has committed to substantial investments to expand QVAC’s open-source ecosystem over the coming months and years, including specialized toolkits for robotics and brain-computer interfaces.
The launch marks a significant strategic expansion for Tether beyond its core stablecoin business, positioning the company to compete with centralized AI providers by offering privacy-focused alternatives that process data locally rather than transmitting it to cloud servers.
