A free-text answer breaks the moment your software reads it
An artificial intelligence (AI) model can write a fine paragraph, then hand your code a paragraph it cannot use. Ask for a fixed structure instead, and the same answer becomes something your system can trust.
An artificial intelligence (AI) model is very good at writing like a person. Ask it a question, and it replies in full sentences, with pleasantries and caveats attached. That is fine when you read the answer yourself. It is not fine when your software reads it instead.
You may already use an AI model to fill in a form, sort a support ticket or read a document, then hand the answer straight to other software. That software does not read English. It looks for an exact pattern, in an exact place, every single time.
Why free text breaks
Picture asking the AI model for a delivery date. One day it answers "the fifteenth of October". Another day it answers "15/10" or "next Wednesday, the fifteenth". Each answer is correct and readable by you. None of them match exactly, so the code expecting a fixed pattern fails, or worse, reads the wrong part of the sentence as the date.
The same problem appears with amounts, names, categories and yes or no answers. A model might write "yes, that should be fine" instead of a plain "yes". A number might arrive as "twenty" instead of "20", or carry a currency symbol one time and not the next.
Free text is fine for a person to read. It is not fine for a computer to trust.
None of this is a fault in the AI model. It is doing exactly what you asked, answering in natural language. The fault sits in asking it to write you a letter, then wiring that letter straight into a system built for a form.
What to ask your supplier
A capable supplier builds around this from the start. They ask the AI model to return its answer in a fixed structure, a set of clearly named boxes, such as date, amount and status, rather than a paragraph. The model still reasons in language behind the scenes, but the final answer arrives in a shape your software can check and use directly.
Ask your supplier three things. First, does the AI model return a fixed structure, or free text that another part of your system then has to guess at. Second, what happens when the model cannot fill every box: does the system flag it for a person, or fail without telling anyone. Third, can you see a record of the raw answers, so a fault can be traced later.
An assistant that only ever talks to a person can get away with free text. An assistant wired into your booking system, your stock records or your accounts cannot. At Yunaris, we build that exchange as a fixed structure from the outset, so the answer is trustworthy before it ever reaches your systems.
