100-word summary
OpenAI launched a beta Excel add-in that builds financial models in plain English. Ask for a discounted cash flow model and GPT-5.4 generates it in native Excel formulas, no CSV export required. The same update connects Moody's, Dow Jones, and MSCI data directly into ChatGPT, turning eight-tab research workflows into single prompts. Investment banking modeling accuracy jumped to 87% from 68% in earlier versions. The catch? Responses run slower during beta optimization, and outputs still need cleanup. What changes: junior analysts might spend Tuesday mornings reviewing AI-built models instead of building them from scratch.
