Ambig-DS - Target (Ask): leaderboard

Metric: Normalized task score (0-100) in the Ask condition (before modeling the agent may ask one question of 50 words or fewer to a scoped answer-only oracle) on the 51 target-ambiguity tasks of Ambig-DS (DSBench data-modeling tasks whose prompt and data no longer fix the prediction target), scored by the original DSBench evaluator as the relative performance gap normalized to 0-1 (times 100, so 0-100; invalid and timed-out runs score 0), code agents in the OpenCode harness with a 2-hour budget; higher is better. Source: arxiv.org. Saturation forecast: Around October 2027. 5 models tracked.
