Baidu Dazi update: cross-device task handoff, desktop browser agent now live

百度搭子更新：电脑手机接力、桌面端内嵌浏览器上线，复杂任务可跨端连续执行

Baidu Dazi now syncs task context between desktop and phone, so you can pick up where you left off across devices. The desktop version gets an embedded browser that auto-opens pages for research and downloads; the phone side supports cloud remote control. Baidu claims 20% faster task completion, 25% better token utilization, 100% simple-task accuracy, 94% complex-task delivery rate, and up to 75% lower credit cost. The post doesn't disclose testing methodology or baselines—treat the numbers as directional.

Why it matters: Baidu's companion app update brings real cross-device task continuity, not a minor tweak. The official numbers on time, token efficiency, and credit cost add real information. But the post doesn't fully explain the measurement baseline, so the score stays below 85.
