Lenovo completed the October 2026 rollout of Tianxi AI 4.5 across AI phones, tablets and AI PCs, with releases on October 20, 27 and 30, respectively.1
2 The update is framed as a workplace assistant: its central idea is to turn a spoken or written instruction into a sequence of actions across connected apps, devices and work materials. Launch coverage describes those capabilities, but does not independently verify every advertised workflow.
A staged rollout across three device types
Tianxi AI 4.5 arrived first on AI phones, followed by AI tablets a week later and AI PCs on October 30. With the PC release, Lenovo said the update covered all three device categories.1
2
The emphasis is on continuity between devices and work scenarios, rather than a new standalone chat interface. The announced use cases span office tasks, meetings and travel, with the PC positioned as a place where more involved work can be carried out.1
3
Super Mode connects apps and work materials
Super Mode is designed to break a natural-language instruction into steps and carry them out across applications. Lenovo’s examples include checking meetings, assigning tasks, organizing to-dos, searching across platforms and sending group notifications.1
2
The reported connectors include Feishu, Lenovo Browser and WeCom. Lenovo says they work with its personal knowledge base, linking local files with cloud materials such as Feishu documents in the same workflow.1
2
A Skills Plaza brings together connectors, multitask collaboration and other skills. Launch reports also describe improvements to PowerPoint generation and a system-control skills package intended to help with device settings and performance issues.1 These are product descriptions; the supplied reporting does not provide independent measurements of how well the features perform.
Meeting notes go beyond transcription
Lenovo says it rebuilt AI Miaojì, its meeting-note feature, and the knowledge base. During meetings, the assistant is reported to provide live transcription and subtitles, contribute ideas during brainstorming, answer questions based on the transcript, and identify key points.3
18
After a meeting, AI Miaojì can generate a summary card, save it to the knowledge base and synchronize it across devices through Lenovo’s personal cloud, according to launch coverage.2
18 The knowledge base is also reported to support questions across up to 20 uploaded files and direct image uploads in chat, for comparisons involving multiple documents or text and images.
18
Voice and travel: some details need qualification
Tianxi AI 4.5 is reported to support full-duplex voice interaction on phones, tablets and AI PCs, allowing users to interrupt or add instructions without repeatedly waking the assistant.3 Coverage also describes a travel scenario in which a user can remotely invoke an AI PC from another device.
2
The available reports do not establish the more specific remote-workflow details sometimes associated with that feature, such as progress tracking, notifications and output management. Treat those as unverified based on the supplied coverage.
What the P7 preview says about local and cloud models
A separate preview report about Lenovo’s AI Host P7 says its Auto mode chooses between local and cloud models according to task complexity, with the stated aim of balancing task results and cost. Users can also select an installed local model directly without using cloud tokens.9 This is P7 preview information, not evidence that every Tianxi AI 4.5 device uses the same model-selection setup.
Another launch report says the AI Host supports 7×24-hour online availability.2 That describes availability; it does not, on its own, confirm uninterrupted autonomous task execution. The clearest supported picture of Tianxi AI 4.5 is a staged three-device rollout focused on connected office actions, meeting assistance and cross-device use, with some travel and AI Host specifics still awaiting fuller substantiation.
