It did not, unfortunately. When CV failed gpt-4o failed as well. I even had a list of valid invoice numbers & dates to help the models. Still, most failed.

Construction invoices are not great.

Did you try few-shotting examples when you hit problem cases? In my ziploc case, the model was failing if red sharpie was used vs black. A few shot hint fixed that.

Tbh, I had run the images through a few filters. The images that went through to AI were high contrast, black and white, with noise such as highlighters removed. I had tried 1 shot and few shot.

I think it was largely a formatting issue. Like some of these invoices have nonsense layouts. Perhaps Qwen works well because it doesn't assume left to right, top to bottom? Just speculating though

I’m very surprised. Have dealt with some really ugly inputs (handwritten text on full ziploc bags etc., stained torn handwritten recipe cards, etc.) with super good success.
