The listing title says that Kimi K3.1 Pro is live, and its release notes state that the model is now available in the app.
The store description says K3.1 Pro has upgrades for 3D creation, coding, writing, and financial analysis. It promotes generation of multiplayer 3D games, high-precision 3D models, and websites, as well as presentation generation and data-analysis work. The listing also describes online preview and editing for 3D models, synchronization across phone, desktop, and web, and remote control of Kimi Work from a phone.
The same page claims an agent-cluster feature that can schedule up to 300 instances across 4,000 steps, alongside office-document and visual-programming features. These are product claims in the Xiaomi App Store listing. The listing does not establish benchmark performance, pricing, which functions require a subscription, availability outside the Xiaomi App Store, or whether every advertised capability is enabled for all users.
