A Comparative Study in Surgical AI: Datasets, Foundation Models, and Barriers to Med-AGI
This paper evaluates the performance of recent Vision-Language Models (VLMs) and specialized computer vision models for surgical tool detection, using large datasets from neurosurgery (SDSC-EEA) and laparoscopic cholecystectomy (CholecT50). Findings indicate that zero-shot VLM performance remains poor, even for large models. Fine-tuning improves results but generalization is limited by data distribution shifts. Crucially, smaller, specialized models significantly outperform VLMs with far fewer parameters, suggesting the bottleneck is specialized data availability rather than model scale. The study advocates for community-driven efforts to pool and label surgical data and develop hybrid AI architectures.

Generalization Across Surgical Domains (CholecT50)
The findings on SDSC-EEA dataset replicate on CholecT50, an independent laparoscopic cholecystectomy dataset with 6 instrument classes. Fine-tuned open-weight LLMs and specialized computer vision models consistently outperform proprietary frontier VLMs, indicating the robustness of the observed patterns.
- Outcome: Zero-shot Gemma 3 27B: 6.87% accuracy (below 34.76% majority baseline).
- Outcome: Fine-tuned Gemma 3 27B: 83.02% accuracy.
- Outcome: YOLOv12-m: 81.37% accuracy.
- Outcome: Proprietary VLMs (GPT-5.4, Gemini 3, Claude 4.6): Lower than fine-tuned models.
