AbstentionBench - underspecified context - MMLU History - Precision: leaderboard

AbstentionBench evaluates whether a model appropriately declines unanswerable or underspecified questions. This slice reports underspecified context - MMLU History - Precision as Abstention Precision (%); values converted from 0-1 to percent. Precision and recall must be read together: always abstaining is not necessarily useful. Scenario/dataset pairs and SFT/DPO/RL checkpoints remain separate; no synthetic overall average.

Metric: Abstention Precision (%). Source: github.com. Saturation forecast: Estimated already saturated. 21 models tracked.
