    I built an open-source AI phone: OpenCyvis. An AI that sees your screen and operates your apps is the most privileged software on your phone. You should choose what model runs it, see where your data goes, and audit every step. 🔗 opencyvis.ai | github.com/opencyvis/open…

    背景 在大多数用户的印象里,GPU(图形处理器)是游戏流畅、视频绚丽的保障,是沉浸在虚拟世界背后的无名英雄。然而,在现代移动计算架构,尤其是在安卓生态中,GPU的角色早已超越了“图形画师”的范畴。它通过诸如OpenCL、Vulkan等通用计算框架,深度参与到机器学习、图像处理、甚至安全计算等关键任务中,成为了SoC(系统级芯片)中与CPU平起平坐的“第二颗大脑”。 正是这种权限与复杂性的与日俱增
