Lenovo introduced its personal AI agent, Tianxi AI 4.5, on Artificial Intelligence PCs (AI PCs) on October 30. This release followed versions for phones, launched on October 20, and for tablets, released on October 27, meaning the update now covers all three device types.
Lenovo positions this version for office workers, offering enhancements for completing work tasks, participating in meetings, and business travel. A central feature is the new Super Mode, which transforms the assistant from a question-answering tool into a task executor.
Tianxi AI 4.5 integrates connectors for Feishu, the Lenovo browser, and WeCom, linking them to a personal knowledge base. This allows for the shared use of local files and cloud documents. A user can issue a single command that prompts the assistant to break down and execute multi-step work across different applications, such as checking meeting schedules, assigning tasks, or finding material and sending a group notification.
A skills marketplace is also available, consolidating connectors, collaborative multitasking, and various skills, including enhanced slide generation. Furthermore, a system management package allows users to customize graphics, power, and system parameters upon request.
The AI note-taking function for meetings has been completely revamped. It now provides real-time transcription with subtitles and can participate in brainstorming as a participant, offering opinions and ideas. Attendees can ask the AI questions during a meeting based on the live transcript, and the system automatically highlights key moments. Upon session completion, summary cards are generated, saved to the knowledge base, and synchronized across devices.
The knowledge base now supports uploading up to 20 files, and images can be uploaded directly into the chat. All three device types support full-duplex voice input, allowing the conversation to be interrupted to add instructions mid-dialogue without repeating the activation word. When the user is away from their workstation, they can use their phone or tablet to initiate a complex task on an office or home AI PC running in Super Mode.
Task progress is visible on the phone or tablet, status notifications are received, and completed results can be previewed and managed remotely. The update also extends to Lenovo's AI Host machines. The AI Host P7 model can access cloud models or function as a local edge computing device. The new Auto mode selects between cloud and local models based on task complexity to minimize unnecessary token usage. These hosts support autonomous, round-the-clock task execution.
