Authors’ Reply: Critical Limitations in Comparing ChatGPT and DeepSeek for Orthopedic Assessment

We respond to comments on our study comparing ChatGPT and DeepSeek for answering orthopedic multiple-choice questions. We clarify that the reported Cohen κ values reflect inter-rater reliability within each model rather than agreement between the two models. All questions were administered in English, and the findings therefore reflect performance in an English-language context. We acknowledge limitations related to reproducibility due to the use of web-based interfaces and address concerns about data contamination. We also correct a typographical error in the reported accuracy for the pelvic and spine injury category.
