Open-weight Qwen3.8-Flash-Next hits a RoboDojo Score of 31.39 with no depth or task-verifier feedback, above GPT-6 Astra's published 28.97 and every listed VLA/WAM baseline.
The lever is the harness. The same Qwen scores 1.90 with RoboProbe, 7.75 with RPent, 21.01 with GAP (Hybrid) and 31.39 with uni-robot-agent. Under that harness GPT-6 Astra reaches 51.90, so a gap to closed models remains.
📊 The numbers
• Qwen costs $1.09 per episode; Astra costs $21.29
• Best VLA/WAM baseline, Xiaomi-Robotics-1: 20.07 Score
• Real robot, 19 tabletop tasks: Qwen 49.50, fine-tuned pi0.5 47.75, zero-shot Dream-1 35.50
• No depth keeps 87.5% of Qwen's score; RGB only without camera parameters drops it to 9.13
🛠️ Try it
• pip install uni-robot-agent, then uni-robot-agent setup --integration robodojo (MIT, Python 3.11, Linux GPU host)
• Reusable ideas: immutable observation snapshots, duplicate-action rejection, pipelined execution (84.5% to 93.8% of motion overlaps model calls)
⚠️ Caveats
• Scores are low in absolute terms; Qwen needs 95.5 min to reach a score of 25, Astra 42.6
• The package has no physical-robot support yet; the real-world benchmark is in-house on one dual-arm platform

Before buying depth sensors or a frontier API, how much of your robot agent's gap is really the harness?
