           |

           | Capturing the egg price from known egg receipts was the
           | problem I was focused on, but you're right that there was
           | also a filtering problem in the original spec. You get my
           | upvote for continuing to make the problem interesting for me!
           | 
           | Had the filtering been done during the initial document
           | storage, then the cost would have been much cheaper than your
           | $2,000 estimate. Essentially binning the receipts based on
           | "eggs" or "no eggs" would be free. But, crucially, what
           | happens when the question changes from price per egg to price
           | per gallon of milk? Now the whole stack would need to be
           | sorted again. The $2,000 manual classification would need to
           | be re-applied.
           | 
           | Isn't traditional ML-based classification cheaper for this
           | problem _at industrial scale_ than an LLM though? The OP did
           | of course attempt more traditional _generic_ off-the-shelf
           | OCR tools, but let 's consider proper bespoke industrial ML.
           | 
           | Just as a off-the-cuff example, I would probably start with
           | building a tool that locates the date/time from a receipt and
           | takes an image snip of it. Running ONLY image snips through
           | traditional OCR is more successful than trying to extract
           | text from an entire receipt. I would then train a separate
           | tool that extracts images of line items from a receipt that
           | includes item name and price. Yet another tool could then be
           | trained to classify items based on the names of the items
           | purchased, and a final tool to get the price. Now you have
           | price, item, and date to put into your database.
           | 
           | Perhaps generating the _training data_ to train the item
           | classifier is the only place I could see an LLM being more
           | cost effective than a human, but classifying tiny image snips
           | is not the same as one-shotting an entire receipt. As an
           | aside, if there 's any desire to discuss how expensive
           | training ML is, don't forget the price to train an LLM as
           | well.
           | 
           | All of this is to say I believe traditional ML is the
           | solution. I'm still not seeing the value prop of LLMs at the
           | industrialization scale outside of very targeted training
           | data generation. A more flippant conclusion might be that we
           | can replace a lot of the parts of data science that makes PhD
           | types get bored with creating traditional ML solutions.

             | Also, playing hotdog-not-hotdog on a receipt, looking for

             | classification task that also has to take place to group

             | an hour. I doubt I got much more than a dozen an hour done.
             | So, my gut reaction is that your estimate on the human cost
