New benchmark reveals LLM agents struggle with complex finance spreadsheets

A new research paper introduces WorkstreamBench, a benchmark designed to evaluate Large Language Model (LLM) agents on complex, end-to-end spreadsheet tasks relevant to the finance industry. The benchmark assesses agents across accuracy, formula correctness, and output formatting, aiming to measure their ability to produce professional-quality financial models and forecasts. While Anthropic's Claude family of models performed best, even the leading agents struggled with tasks beyond simple calculations and frequently failed to meet professional finance standards, indicating a gap between current LLM agent capabilities and real-world enterprise demands.

    WorkstreamBench: Evaluating LLM Agents on End-to-End Spreadsheet Tasks in Finance

    LLM agents are increasingly expected to carry out end-to-end workflows, producing complete artifacts from high-level user instructions. To meet enterprise needs, frontier AI labs have developed agents that can construct entire spreadsheets from scratch. This is especially relevan…
