Excel Modeling Benchmark v1.1
Professional Work · 2026-10-19
Excel Modeling Benchmark v1.1 reruns EMB's 51-task private test set with the GPT-6 Luna rubric judge and template-scoring fixes. Agents build investment-banking and private-equity Excel models (LBO, DCF, M&A, operating, comps, dataroom and miscellaneous) from a prompt and source files; template mode is graded by exact cell match against the gold workbook and scratch mode by a partial-credit rubric over numerical, formula and presentation checks. Kept separate from EMB v1 because the grading changed.
