This workshop introduces attendees to the expansive realm of Large Language Models. We initiate the session with the basics of LLMs to provide a solid grounding in the understanding of these models. The course progresses to fine-tuning approaches that allow customization of LLMs to meet specific task requirements. Attendees then learn about the evolving concept of prompt engineering, aimed at optimizing the usage of LLMs. An intriguing aspect covered is Langchain, a tool for linking and analyzing language models. The journey continues by examining popular open-source LLMs like Llama and CodeLlama, potentially sparking ingenuity among aspiring developers. Drawing the workshop to its conclusion, we delve into productionizing LLMs using vector stores, arming you with essential skills to deploy your own language model.
