Generative AI tools such as ChatGPT, DALL-E, Bard, and Stable Diffusion have received a lot of press, as of late. In this course, information technology professional and teacher Fred Nwanganga provides learners with a gentle introduction to what these tools are, how they work, and how they fit into the larger AI ecosystem. Explore generative AI with large language models (LLMs). Learn what generative AI and LLMs are, what types of LLMs exist, and how they have evolved. Dive into neural networks, including how they learn and an overview of deep learning and its transformative impact. Discover the building blocks of LLMs, such as the transformer architecture, encoders and decoders, the attention mechanism, and self–attention. Plus, go over the societal implications of LLMs.
