Core Viewpoint - The article discusses the transformative potential of Agentic AI in biomedical research, highlighting its ability to perform labor-intensive tasks traditionally done by humans, such as literature review, hypothesis generation, and data analysis, through advanced algorithms and collaborative intelligent agents [2][3][4]. Key Algorithms Driving Agentic AI - Agentic AI is primarily driven by three key algorithms: 1. Large Language Models (LLMs) like GPT-5.2 and Claude Opus 4.5, which convert human instructions into computational operations [13]. 2. Reinforcement Learning (RL), which aligns AI behavior with human preferences through reward mechanisms [13]. 3. Evolutionary Algorithms, inspired by biological evolution, optimize AI responses and designs [13]. Seven Key Features of Agentic AI - The article identifies seven essential features for constructing Agentic AI in biomedical research: 1. Reasoning 2. Verification 3. Reflection 4. Planning 5. Tool Use 6. Memory 7. Communication [10][13]. Current Applications in Biomedical Research - Agentic AI has been applied across various stages of biomedical research, including: 1. Automated literature review and information extraction. 2. Hypothesis generation based on literature searches. 3. Experimental design and data analysis. 4. Coordination of end-to-end research processes [11][12][15]. Challenges and Opportunities - The deployment of Agentic AI systems in collaborative scientific research faces challenges such as: 1. Data processing and integration difficulties due to format and dimensionality issues. 2. Privacy and security concerns when handling sensitive patient data. 3. High computational costs and energy consumption associated with training and inference [20]. Future Outlook - The authors anticipate a shift from specialized single-agent systems to general multi-agent systems, emphasizing the importance of adaptive autonomy. Agentic AI should effectively recognize when to consult human experts for ambiguous or high-risk tasks, rather than pursuing complete autonomy [19].
