Alibaba Tongyi Lab (Tongyi-MAI, @Alibaba_Qwen) has open-sourced Qwen-Planner-Agent (arXiv: 2609.29892, Project: tongyi-mai.github.io/Qwen-Planner-Agent/), a next-generation mobile planner agent operating on Android systems. Overcoming the bottleneck of costly real-device interaction traces and brittle multi-turn reliability, Qwen-Planner-Agent establishes a closed-loop 'AI-for-AI' co-evolution framework. Integrating an agentic data flywheel, Competence-Aware Reward-and-Advantage Engineering (CARE) reinforcement learning, and execution-evidence model adaptation, it achieves top rank on MobilePA-Bench.

Core Background & Industry Pain Points
Mobile operating systems represent a critical frontier for autonomous agents, requiring models to navigate asynchronous UI refreshes, unpredictable popups, and multi-app workflows (e.g., cross-platform travel booking). However, real-device execution cannot be parallelized like game simulators. Gathering human interaction trajectories on physical smartphones is prohibitively slow, while existing agents suffer from context drift and circular tool invocations on extended step horizons.
Architecture Highlights & Internals
Tongyi Lab introduces an AI-for-AI co-evolution framework structured into three interconnected loops: (1) AI for Data deploys specialized agent teams to synthesize scenarios, collect device trajectories, and balance curriculum difficulty based on upstream training feedback; (2) AI for Training leverages Competence-Aware Reward-and-Advantage Engineering (CARE) within online RL, penalizing redundant screen swipes and reasoning bloat; and (3) Runtime Model-Harness Co-Evolution logs structured failure traces into an execution-evidence database to iteratively refine skills, memory schemas, and sub-agent routing.
Authoritative Benchmarks & Measured Scores
Evaluated on the MobilePA-Bench benchmark spanning over 100 diverse Android applications: Qwen-Planner-Agent ranks first across tool precision, memory retention, and multi-agent coordination. CARE reinforcement learning slashed average token consumption by 34.2% while reducing physical interaction steps by 21.6%. General reasoning evaluations confirmed zero degradation on non-mobile tasks.
