Fuente: WIPO "tomato" Embodiments of this specification disclose model authenticity evaluation methods, apparatuses, and devices. The method includes: obtaining first question data used to perform authenticity evaluation on a target model, and inputting the first question data to a target model to obtain a first response result corresponding to the first question data; extracting a named entity included in the first question data, and constructing second question data based on the named entity and the first question data, where the second question data is used to trigger the target model to output an analysis basis and a result for the first question data; inputting the second question data to the target model to obtain a model prediction result corresponding to the second question data; and determining an authenticity evaluation result of the target model based on the first response result and the model prediction result.
