That creates a new problem for commercial real estate firms: A document can look ready long before it is safe to use. An AI system may retrieve a document, summarize it, add figures to a spreadsheet and prepare an email. The way to achieve that is not to ask one AI model to handle every part of the job. The underlying AI model did not change, but the gains came from providing better context, directing each step to the appropriate tool and independently checking the result. These results illustrate a larger point: Better work does not necessarily come from buying a larger model.
