ChatGPT-4 correctly answers most dermatology board questions, but struggles with higher-order thinking and needs better visual diagnostic skills.

## Contribution

This study evaluates ChatGPT-4's dermatological knowledge using board questions and Bloom’s Taxonomy.

## Key findings

- ChatGPT-4 answered 77.5% of dermatology board review questions correctly.
- Performance decreased with higher-order thinking requirements.
- Visual diagnostic capabilities need improvement for clinical use.

## Abstract

Our study demonstrated the ability of ChatGPT-4 to answer 77.5% of all sampled text-based board review type questions correctly. Questions requiring the recall of factual information were answered correctly most often, with slight decreases in correctness as higher-order thinking requirements increased. Improvements to ChatGPT’s visual diagnostics capabilities will be required before it can be used reliably for clinical decision-making and visual diagnostics.
