Abstract: A computer system receives an image from a picker, which indicates an out-of-stock target item and potential replacements items. The system provides, to a machine learning model, a prompt requesting identification of the target item and the potential replacement items in the image.

The system generates a first list of potential replacements items based on the list of potential replacement items identified in the image and a second list of replacement items from the target item by applying one or more replacement models to the identified target item. The system may merge the two lists and assign replacement scores to each item in the merged list to create a list of recommended replacement items. The system generates a message based on the image and the list of recommended replacement items.
