    "body_text": "Training computer-use agents directly in live systems is costly and risky. WildAWM uses open-source models to synthesize controlled environments spanning graphical interfaces, tool services and command lines. Quality gates test solvability, difficulty and verifier robustness with agent runs, judge agreement and counterfactual probes. The pipeline produced 341 long-horizon environment-task pairs, some requiring more than 100 steps; a frontier model solved 60 percent. Two Qwen models trained only in these worlds improved across eight out-of-distribution benchmarks. The collection is finite, but its execution checks make generation more than prompt-written scenery.",
