The AI Model Audit: Copilot, Claude & ChatGPT Under Review

Paul is a highly respected FP&A professional, corporate trainer, consultant, Advanced Financial Modeler, and Microsoft Excel MVP. With an audience of more than 100,000 LinkedIn followers, he is widely recognised for helping finance professionals and organisations improve their financial planning, forecasting, modeling, and business strategy capabilities.

Earlier this year, David gave Claude and ChatGPT the same challenge: build a financial model from scratch. Watching both tools interpret the brief, structure their calculations, and compete in real time was exciting. It also raised a new set of questions.

Building a model is one thing. Can AI recognise whether a completed model is reliable? Can it review a human-built model, identify weaknesses, and judge the quality of its assumptions and structure?

On Friday, 18 September 2026, David and Paul will put this to the test during The AI Model Audit: Copilot, Claude & ChatGPT Under Review.

This time, Copilot, Claude, and ChatGPT will review a human-built financial model. David and Paul will examine how each tool identifies errors, questions assumptions, assesses structure, and responds to the complexities of a real modeling environment.

The session will also explore what AI can contribute to the model-review process and what still requires professional expertise and judgement.
