Summary content generation and validation for parts on listing platforms

A computer-implemented method comprising:

• accessing, by at least one of one or more servers of the listing platform, a first input data from an item listings data store of the listing platform, the first input data comprising a first plurality of attribute-value pairs for attributes of a first part item from a first part item listing on the listing platform, the first part item comprising a physical item having one or more compatibility requirements with one or more other physical items, the first plurality of attribute-value pairs for the attributes of the first part item providing information regarding the compatibility requirements;
• causing, by at least one of the one or more servers of the listing platform, a first generative model to generate a first content for the first part item listing by providing one or more pre-defined generation prompts and the first input data including the first plurality of attribute-value pairs to the first generative model, the first content comprising natural language text providing compatibility information for the first part item;
• causing, by at least one of the one or more servers of the listing platform, a second generative model to determine whether the first content is valid based on consistency of the natural language text of the first content with the compatibility requirements by providing one or more pre-defined validation prompts and the first content and the first plurality of attribute-value pairs to the second generative model;
• responsive to a first output from the second generative model rejecting the first content, withholding the first content from presentation on a user device in association with the first part item listing and causing, by at least one of the one or more servers of the listing platform, a third generative model to generate a first tuned generation prompt by providing to the third generative model one or more selected from the following:
• the first content, and at least a portion of the first output from the second generative model;
• and
• adding, by at least one of the one or more servers of the listing platform, the first tuned generation prompt to a repository of pre-defined generation prompts.

A listing platform having one or more servers comprising:

• a processor;
• and
• a computer storage medium storing computer-useable instructions that, when used by the processor, causes the listing platform to perform operations comprising:
• accessing, by at least one of the one or more servers of the listing platform, input data from an item listings data store of the listing platform, the input data comprising a plurality of attribute-value pairs for attributes of a first part item from a first part item listing on the listing platform, the plurality of attribute-value pairs comprising one or more attribute-value pairs for fitment data for the first part item listing and one or more attribute-value pairs for item attribute data for the first part item listing, the part item comprising a physical item having one or more compatibility requirements with one or more other physical items;
• selecting, from a repository of pre-defined generation prompts, one or more pre-defined generation prompts for the input data;
• causing, by at least one of the one or more servers of the listing platform, a first generative model to generate content by providing the one or more pre-defined generation prompts and the input data including the fitment data and the item attribute data to the first generative model, the content comprising natural language text providing summary information for the a first part item listing including compatibility information and item characteristic information;
• causing, by at least one of the servers of the listing platform, a second generative model to determine whether the content is valid based on consistency of the natural language text of the content with the fitment data and the item attribute data by providing one or more pre-defined validation prompts and the content and the plurality of attribute-value pairs to the second generative model;
• when a first output from the second generative model indicates the content is valid, providing, by at least one of the one or more servers of the listing platform, the content within a web page communicated to a user device for presentation;
• and
• when the first output from the second generative model indicates the first content is not valid, withholding the first content from presentation on the user device in association with the first part item listing.
