Tether (USDT) has expanded into the AI business by unveiling its decentralized local AI platform, 'QVAC'. Tether described QVAC as 'AI infrastructure that operates without reliance on centralized clouds'. QVAC is designed to allow users to run AI models directly on their devices and supports Linux, Windows, Mac, Android, iOS, and more. It is also reported to include P2P-based inference capabilities. Tether presented the direction that 'just as money should move without permission, data and AI should also be directly controlled by users,' emphasizing privacy protection, offline use, and censorship resistance compared to central server-based AI. Additionally, MedPsy, the first medical-specialized AI model of QVAC, was also unveiled. Tether claimed that 'despite being a small local model, it recorded competitive performance compared to large models in some medical benchmarks'.
