Performance of Artificial Intelligence Chatbot on the Canadian Otolaryngology in-Training Exam: Unlocking Insights on the Intersection of Technology and Education
Bibliographic record
Abstract
Importance The performance of large language models has been compared to that of physicians. Objective To evaluate the performance of ChatGPT-4 in the field of otolaryngology and head and neck surgery (OTOHNS) residency training. Design Observational. Setting Virtual. Participants ChatGPT-4. Interventions All questions from the OTOHNS National In-Training Exam (NITE) for 2022 and 2023 were submitted to ChatGPT-4. Answers were graded by 2 reviewers using the official grading rubric, and the average score was used. Mean exam results from residents who have taken this exam were obtained from the lead faculty. Main Outcome Measures Z -tests were used to compare ChatGPT-4’s performance to that of residents. The questions were categorized by type (image or text), task, subspecialty, taxonomic level and prompt length. Results ChatGPT-4 scored 66% (350/529) and 65% (243/374) on the 2022 and 2023 exams, respectively. ChatGPT-4 outperformed the residents on both exams, among all training levels and within all sub-specialties except for the general/pediatrics section of the 2023 exam ( Z -test −2.54). For the 2022 exam, ChatGPT-4 would rank in the 99th percentile among post-graduate year (PGY)-2 and 73rd percentile among PGY-4 classmates. For the 2023 exam, it would rank in the 99th percentile among PGY-2 and 71st percentile among PGY-4 classmates. ChatGPT-4 performed best on text-based questions (74%, P < .001) with an effect size of 1.27 (confidence interval (CI): 0.99-1.55), level 1 taxonomic questions (75%, P < .001) with an effect size of 0.084 (CI: 0.03-0.14) and guideline-based questions (70%, P = .048) with an effect size of 0.11 (CI: 0-0.23). It had no significant difference in performance based on subspecialty ( P = .36) or prompt length ( P = .39). Conclusions ChatGPT-4 not only achieved passing grades on 2 versions of the Canadian OTOHNS NITE, but it also significantly outperformed residents. Relevance This study underscores a critical need to redesign residency assessment methods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
