Rank = position among every model config we tested in that task area (lower is better). Sorted by biggest gap first.
Same task, both models — judged
Both models answered the same test case; an independent judge graded each. Quotes are the judge's actual rationale.
AI Strategy
Internal RAG pilot (Pilot-to-Production Test)
“The candidate provides a highly realistic, structured, and comprehensive assessment that directly addresses the specific risks of the scenario (ACLs, stale data, lack of eval/ownership) with actionable, concrete solutions and metrics.”
“The response covers all requested sections and correctly identifies the core risks, but it relies on generic boilerplate and invents multiple non-existent departments to handle the fixes, making the practical advice unrealistic for the scenario.”
