Dive deep into the capabilities of Large Language Models (LLMs) with a focus on structured outputs, which are crucial for advanced data manipulation and application-specific customization. This session will explore the tools and techniques for interacting with and optimizing LLMs, highlighting practical strategies for fine-tuning and leveraging structured data formats like dictionaries and JSON. Participants will gain hands-on insights into enhancing the functionality of both proprietary and open-sourced LLMs through structured outputs and function calling.
