LG-Bench - Chemistry: leaderboard
LG-Bench (2026): main Table 2 accuracy on 10,200 life-science multiple-choice questions: Medicine 3210, Biology 3630, Chemistry 3360. Identical prompt/evaluation protocol; source model labels do not bind base versus instruction checkpoints or API snapshots, so study identities remain separate. The independently reviewed inconsistent Llama-3.1-70B row is omitted pending correction, not repaired or replaced. GCS/KBS graph diagnostics are not accuracy and are not included.
Metric: Accuracy (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 28 models tracked.
