LLM Course – Build a Semantic Book Recommender (Python, OpenAI, LangChain, Gradio)

Discover how to build an intelligent book recommendation system using the power of large language models and Python. Learn to transform book descriptions into mathematical representations that enable precise content-based matching. By the end of this course, you'll have built a recommendation engine that helps readers discover their next favorite book.
