Table 1. Root-Mean-Square-Error (RMSE) of the Energy (Second Column) and Forces (Third Column) for All of the Models^a.

model	RMSE [meV/atom]	RMSE (%RMSE) [meV/Å]
PBEsol	7.0	120 (14.8%)
r2SCAN	6.5	141 (15.8%)
PBE0	6.5	165 (17.2%)

^aIn the third column, the number in parentheses indicates the %RMSE relative to the standard deviation of forces within the test set.
