SFT-4B-ScaleCUA-MixedOpen-GGUF

SFT-4B-ScaleCUA-MixedOpen is a Qwen3-VL-4B-Instruct checkpoint supervised-finetuned on 1,430 Lite.ScaleCUA trajectories pooled in equal proportion from three open-source teacher agents — Qwen3.8-27B (478 trajectories), Qwen3.5-27B (477), and EvoCUA-8B-20260105 (475), one trajectory per task, 1,390 of which are full successes — trained via cua-lite + slime with token-level SFT on assistant-action tokens over 3 epochs (1,070 steps) on 2x 80GB H100 GPUs. This epoch-3 checkpoint (iter_1070) is the strongest of the measured ScaleCUA SFT arms on the Lite.OSWorld eval split (332 tasks, greedy decoding, one host/protocol), reaching a mean episode return of 0.3927 (125/332 success) — beating the best single-teacher arm (Qwen3.5-27B, 0.3682) by +0.0245/+8 tasks and the closest-matched single-teacher arm (Qwen38, 0.3623) by +0.0304/+10 tasks, both clearing the paper's >0.02 mean and ≥7 task threshold for a real effect, though the authors caution this isn't a clean single-variable ablation since teacher identity, trajectory count, and task coverage all move together. Notably, doubling trajectories per task (-MixedOpen-cap2, 2,520 trajectories) actually underperforms this model by −0.0125/−5 tasks, suggesting broader task coverage matters more than redundant per-task examples, and per-domain results show multi_apps coordination (28% of tasks) remains the weakest capability across all teacher mixes at just 0.159 mean return. The model requires the qwen3_vl adapter config with full_history_size=4 for correct serving, since it was trained on that specific history-rendering protocol.
