* The APEX-Agents benchmark evaluates how well AI agents can perform realistic professional tasks that may involve using files and tools such as documents, spreadsheets, PDFs, email, chat, and calendars. For each assignment, the model must satisfy a set of predefined criteria. The reported percentage represents the probability that a randomly selected task is completed correctly on a single attempt (Pass@1).
