Overview

Benchmarking of LLMs across clinical reasoning tasks has expanded substantially, with studies now covering surgical decision support, patient education, specialist-level question answering, and neurovascular health communication. Performance patterns across these domains reveal consistent themes of model variability, ChatGPT relative strength, and domain-specific limitations.

Cross-Domain Performance Patterns

ChatGPT consistently emerges as among the stronger performers across evaluated clinical domains, including pediatric UPJO surgical management, brain aneurysm patient education, and dental patient communication. However, no model demonstrates uniform excellence across all domains or evaluation criteria, and performance remains inconsistent within individual studies.

Model-Specific Risk Profiles

Microsoft Copilot has been specifically identified as exhibiting "deceptive confidence" in pediatric surgical scenarios — generating authoritative-appearing responses with elevated misinformation risk. This risk profile is distinct from models that perform poorly but transparently; deceptive confidence is considered a more dangerous failure mode in clinical contexts.

Evaluation Dimension Variability

Studies assess LLMs across heterogeneous dimensions including scientific accuracy, comprehensiveness, empathy, conciseness, clarity, and guideline adherence. Performance rankings shift depending on which dimension is prioritized, complicating simple model comparisons. Standardized evaluation frameworks applicable across clinical domains remain an unmet need in the field.

Patient vs. Clinician Perception

A recurring finding across multiple studies is that lay users (patients) tend to rate LLM responses more favorably than clinicians do. This perception gap — documented in brain aneurysm education and likely generalizable — underscores the risk of patient over-reliance on AI-generated medical content and reinforces the importance of physician oversight in patient-facing LLM deployments.
