SupraBench - Binding Affinity MAE (Few-Shot): leaderboard

SupraBench (2026) tests LLMs on supramolecular host-guest chemistry built with domain experts. This board is the mean absolute error of the predicted binding affinity (log Ka) under standard aqueous conditions, with three to five in-domain demonstrations; lower is better.

Metric: Mean absolute error of the predicted log Ka of host-guest binding under standard aqueous conditions (2,609 records), three to five in-domain demonstrations; lower is better. Source: arxiv.org. Saturation forecast: Around May 2027. 8 models tracked.
