Abstract: Use of a language model to automatically perform visual assessment of quality of an item being fulfilled by a picker. The online system receives an image of the item and identifies a set of potential problems associated with the item. The online system generates a plurality of prompts for input into the language model including the image and one or more questions each corresponding to a respective potential problem of the set potential problems. The online system requests the language model to generate, based on the plurality of prompts, a feedback response for each potential problem. The online system generates an aggregated output by aggregating the feedback response for each potential problem, and based on the aggregated output, a second message that identifies one or more relevant problems associated with the item. The online system causes a device of the picker to display the second message.

Abstract: An online system uses a trained machine-learning model to create an online cart or a physical cart for a user of the online system. Upon receiving a signal with an indication about an interaction by the user with one or more items via a first conversion channel of the online system, the online system retrieves one or more candidate items for the user to convert via a second conversion channel of the online system that is different from the first conversion channel. The online system applies the machine-learning model to output a conversion score for each retrieved candidate item that indicates a likelihood of conversion. Responsive to the conversion score being above a threshold score, the online system generates a user interface at a device associated with the user prompting the user to use the second conversion channel for conversion of each retrieved candidate item.

Abstract: An online system displays an ordering interface, and responsive to receiving a request from a client device to place an order including one or more items to be collected from a retailer location, the system retrieves data associated with each item. The system accesses and applies a machine-learning model to predict a likelihood of each item being a predictable availability item having at least a threshold measure of fluctuating availability throughout the day at the retailer location based on data associated with a corresponding item. The system identifies a set of predictable availability items based on the predicted likelihood(s) and predicts an availability of each identified predictable availability item at the retailer location during a future timeframe. The system then updates the ordering interface to describe the predicted availability of each predictable availability item at the retailer location during the future timeframe.
