Extended Data Fig. 2. The ESM Family of models.

Extended Data Fig. 2

(a) Performance of ESMIN on ClinVar (2,400 genes with a total of ~27k pathogenic and benign variants, class balanced per gene) compared to other ESM family ensembles and individual models. ESM_Family is composed of the 11 ESM models contributing to ESMIN. ESM1b + 2 is the equal-weight average of the ESM1b and ESM2-650M models and ESM1v is the ensemble of the 5 individual ESM1v models. (b) Performance evaluation on ProteinGym (120 organismal fitness and activity DMS assays, across 101 proteins). The top right panel shows the percentage of DMS assays for which an ESM ensemble outperforms all individual ESM family models. (c) Heatmap of Spearman correlations between ESM model predictions that contribute to ESMIN. (d) The fraction of model predictions included in ESMIN and the Spearman correlation with ESMIN are shown for each model. (e) Effect of adding ESM2-15B to the family; ESMIN and average ensemble performance on ClinVar (top) and ProteinGym DMS (bottom), showing negligible additional gains from including ESM2-15B.
