Definition and comparison boundaryinternal methodology

Can the model produce useful work in a professional knowledge-work setting?

Professional analysis, document, finance, office, or domain-specific tasks. Higher is better. This benchmark reports points rather than percent correct.

This is a publisher-defined internal evaluation. The task set or grading details are not fully public, so treat it as directional evidence.

Across different effort settings, Anthropic says 16 of 18 Opus 5.5 reports cleared its quality bar; Claude Fable 5.1 and Claude Opus 5 cleared no attempt. The report describes this internal task and grader but does not publish per-effort results.
