In this episode of "The Science Circuit," we delve into the intriguing world of Large Language Models (LLMs) such as GPT and BERT, exploring their evolution from basic rule-following machines to sophisticated AI systems capable of understanding and generating nuanced human-like text. We discuss the transformation of AI through technological advancements from simple if-then logic systems to complex neural networks that mimic human brain functions. By tracing their development and application, we uncover how these models are not only revolutionizing the way machines comprehend language but also broadening the scope of tasks they can perform, making them increasingly similar to human interactions.
