A recent analysis has revealed significant discrepancies in ChatGPT's performance when handling financial spreadsheets, despite OpenAI's claims of high accuracy. While OpenAI reported an improvement from 43.7% to 87.3% on an internal benchmark for building financial models, an independent test by Wall Street Prep gave ChatGPT a score of 2.5 out of 10 for a real-world task involving an Apple financial model. This disparity highlights different testing methodologies, with vendor benchmarks focusing on isolated sub-tasks versus independent tests evaluating complete workflows. Although ChatGPT performs well on basic spreadsheet functions, its accuracy drops sharply on tasks requiring multi-step processes or multiple linked sheets, a common scenario in corporate finance. AI
