Chatgpt vs purpose built ai for cre underwriting: which one can finish the job?

I keep seeing people recommend chatgpt for financial modeling and I need to push back because I spent a month testing it for multifamily underwriting and the results were not close to usable. Pasting rent rolls, T12s, operating statements and asking it to build models, you get fragments. A few formulas, a cash flow table, maybe a cap rate calculation. Nothing ties together into a workbook you could hand to an investment committee.
