In this video, we’ll go through an introduction on LLM-based agents. We’ll start with discussing some intuitions about agents in general and their implementation, covering from Python + API implementations, to OpenAI function calling and LangChain agentic implementations. Then we dive into LangChain as a framework to build interesting agents exploring some core features.
