WTM-Bench (VBA) - Soft Score: leaderboard

WTM-Bench (2026) gives a model a public Excel workbook with its derived artifacts removed and a concise level-3 request, and asks it to recreate the formulas, charts, pivot tables or conditional formatting by writing code in a tool loop of up to 10 turns; outputs are graded programmatically against the original workbook. Here the model drives Excel through VBA. Score is the soft score, a partial-credit similarity to the target workbook, in percent; higher is better.

Metric: Soft score (%; weighted component similarity of cells, formulas, charts, pivot tables and conditional formatting to the target workbook, partial credit; the model drives Excel through VBA; 150 WTM-Bench tasks at query level 3 (concise, abstract requests); the authors' tool-calling loop that executes code against the workbook, shows the resulting workbook state and allows up to 10 turns; deterministic programmatic grading). Source: arxiv.org. Saturation forecast: Around February 2027. 6 models tracked.
