Personalized Large Language Models (PLLMs) enhance AI interactions by adapting to individual user needs, preferences, and communication styles.

• Leverage user profiles, historical dialogues, and interaction patterns to create contextually relevant responses
• Address the limitations of general LLMs by incorporating user-specific knowledge
• Enable more natural, relevant interactions tailored to individual requirements
• Create applications spanning medical, support, education, and security domains

Medical Impact: PLLMs can transform healthcare by providing personalized medical assistance, adapting to patient histories, and delivering contextually appropriate health information—potentially improving care outcomes while maintaining the human touch in digital health interactions.
