The passage around this formula
Here denotes the model’s parameters and H denotes everything about the evaluation procedure that is not the model itself — the exact prompt template, the number of few-shot examples, whether a chat template is applied, how the model’s free-text output is parsed into a scored answer, and the decoding configuration. A vendor publishes one value of s . An independent lab computing its own s' is implicitly testing whether f(, H) = f(', H') , and a mismatch could in principle come from either argument.

A function assigns an output to each allowed input. The expression f(x) means “apply f to x”.
