Where the article explains it
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.
The passage around this formula
Treat a published benchmark score as the output of a function of two arguments: the weights being scored, and the procedure used to score them. 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 variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
