Bowen Wang(@BowenWangNLP):RLVR has become the recipe for agentic post-training. But for Computer-Use Agents, the bottleneck is not the algorithm, it is the data. 🐌 🚀 We introduce CUA-Gym: a scalable, lightweight synthesis engine that turns arbitrary task queries into verifiable RLVR data for computer-use agents. The largest open CUA RLVR dataset to date: 🎯 32,122 verifiable RLVR tasks with programmatic setup scripts + rewards 🌐 110 environments: 16 desktop apps + 94 synthesized mock web apps 🏆 Qwen3.5-based CUA models trained with GSPO reach 72.6% on OSWorld-Verified and 56.6% on WebArena 📄 Paper: https://t.co/cdvHJPzgb1 🏠 Homepage: https://t.co/kvhaOQxNx7 🤗 Dataset: https://t.co/w5vOIRdchR 💻 Codebase: https://t.co/CcRlNTlS1c 🧩 Environments: https://t.co/fNZ6YAI8LD 🧵[1/6]
