Concept

Pass@1

Pass@1 measures the fraction of problems a model solves correctly on its first and only attempt. It is the strictest member of the Pass@k family, where Pass@k gives credit if any of k sampled attempts succeeds.

The rest of “Pass@1” is a premium feature: every concept in the library gets a precise, practitioner-focused write-up like this one, cross-linked straight from the paper summaries that use it.
