[Tencent Launches OS-Level AI Assistant 'Marvis'] According to Golden Finance, on May 21, Tencent announced the official launch of its OS-level AI assistant, Marvis (马维斯). The official website (Marvis.qq.com) is now open for downloads, and no invitation code is required for use. As introduced, Marvis integrates terminal systems, files, applications, computing power, and cross-device connectivity into a unified AI middleware layer, with six collaborative agents pre-installed at launch. Marvis offers two modes: Efficiency Mode and Privacy Mode. Privacy Mode utilizes an on-device large model, ensuring all data processing, image recognition, and conversations are completed locally without uploading to the cloud. It can even function offline, catering to high-sensitivity scenarios such as finance, legal, and HR. Additionally, in critical areas involving privacy, security, and payments, it hands control back to the user for confirmation. (Sina Finance)
