Tencent has released an updated version of Marvis, changing the product concept from a simple artificial intelligence assistant to a full-fledged AI butler. This new version focuses on four continuous agents that manage devices and digital assets: PC, files, browser, and software. According to coverage by Sina Tech and ZhiDongXi between September 20 and 24, 2026, the official English name of the product is Tencent / Marvis.
This review focuses on the desktop butler team and the claimed task completion rates. It is important to note that this differs from materials about Tencent Yuanbao HarmonyOS / Hunyuan Hy4 and is not news about large language model (LLM) weights.
Unlike office agents, which are primarily optimized for document or slide delivery, Marvis prioritizes constant management of personal devices and digital resources. A 'butler team' section appears in the sidebar interface, informing users about the specialization of each of the four roles.
The PC butler is capable of performing tasks such as intelligent cleaning, troubleshooting, configuration changes, hardware checks, and performance tuning. It utilizes a knowledge base based on the experience of Tencent's enterprise IT solutions and over 100 quick commands, with the team claiming an approximate 92 percent task completion rate on PCs, although these figures remain vendor claims.
The file butler includes a local knowledge base loop that allows it to discover, create, update, and collaborate on collections. It indexes local and cloud files, understands and tags them, and then groups them into libraries. Tencent Docs is already integrated, and WeCom Docs is listed for the next batch.
The software butler handles the installation, updating, and management of applications for PCs, games, and Android apps that can be used on the desktop. The browser butler completes the first wave of the four agents, as stated in the product notes.
Hardware partners mentioned include OEM preloads/plugins, as well as chip-level work with Intel and Qualcomm (including device-level optimization related to OpenVINO). Furthermore, customized builds from Kylin and UnionTech are expected for government and corporate parks.
Development plans indicate the opening of user-created butlers at the end of October through natural language skill, tool, and MCP configuration. Broader availability is planned for November, along with the addition of gaming and lifestyle specialists. For PC users following agents in China, the specific news about Marvis is the team of four butlers with a claimed PC task completion rate of around 92 percent, emphasizing device management priority rather than the introduction of a new foundational model.
