Why Specialist Models Still Matter: A Heterogeneous Multi-Agent Paradigm for Medical Artificial Intelligence
arXiv:2605.29744v1 Announce Type: cross Abstract: The impressive performance of generalist large language models (LLMs) such as GPT and Claude in healthcare raises a critical question: will domain-specific medical specialist models become obsolete? We argue that the future of medical artificial intelligence (AI) lies not in building monolithic medical foundation models, nor in replacing human expertise, but in orchestrating collaboration among generalist LLMs, domain-specific specialist models, and clinicians. We propose HetMedAgent, a heterogeneous medical multi-agent framework that enables c
The proliferation of generalist LLMs in healthcare necessitates a re-evaluation of the role of specialized AI, leading to proposals for hybrid collaboration models.
This development indicates a maturing understanding of AI deployment in critical sectors, moving beyond monolithic models to integrated, human-AI systems, which is crucial for ethical and effective adoption.
The paradigm shifts from a 'generalist vs. specialist' AI debate to one advocating for heterogeneous multi-agent collaboration, involving general LLMs, specialty models, and human experts.
