FaraGen demonstrates that scalable synthetic data generation via multi-agent task proposal, automated solving, and multi-verifier filtering can produce high-quality CUA training data at ~$1 per trajectory. On the newly introduced WebTailBench, Fara-7B achieves 38.4% versus 25.7% for OpenAI computer-use-preview and 19.5% for UI-TARS, though frontier reasoning models (GPT-5: 60.4%, o3: 52.7%) remain substantially ahead on complex multi-step tasks. Positive data and inference step scaling trends suggest further improvements are achievable, and Fara-7B's SFT-only training shows equivalent step-budget scaling to RL-trained UI-TARS, a surprising finding that challenges assumptions about the necessity of RL for agentic scaling.",
