LabOSBench - Activation & Alignment: leaderboard

Activation and alignment operations in LabOSBench (Zou et al., 2026), such as switching on beams and high voltage, aligning lasers and diaphragms, focusing and centering stages, across its web-based scientific-instrument simulators. Each subtask starts from its canonical pre-state with a 50-step budget and runs twice; the score is the percent of successful runs averaged over the category's subtasks; higher is better.

Metric: Subtask Success Rate (%; mean over the category's operation-level subtasks, 2 runs each). Source: arxiv.org. Saturation forecast: Around 2031. 9 models tracked.
