Rachel Thomas highlights Inverse IFEval, a benchmark measuring models' ability to follow out-of-distribution instructions, including:

"The ability to reliably follow out-of-distribution instructions while suppressing rigid training biases is a critical dimension of robustness" — i.e., models shouldn't just learn to game the evaluation patterns they saw in training.
