ReAct prompting (Reasoning and Action) is a powerful AI technique for building complex systems that combine reasoning with tool use. In this video, I break down ReAct prompting through three hands-on examples using LangChain, OpenAI, and various tools including DuckDuckGo search, Wikipedia, and calculator functions.
We start by understanding how ReAct works with its thought-action-observation loop, then build two working examples using LangChain agents and tools. I show you how to set up your environment, configure agents, and create custom tool chains for solving multi-step problems. The first example uses search and math tools to solve complex time calculations, while the second example leverages Wikipedia for fact-checking. Finally, we explore a manual ReAct prompt based on the original research paper to see how the technique works under the hood.
Throughout the video, you'll see real results, including both successes and failures, giving you an honest look at ReAct prompting's capabilities and limitations. I explain why token costs can be high with this approach, when to use ReAct versus simpler solutions, and share tips for improving prompt reliability. By the end, you'll understand how to implement ReAct prompting in your own projects and know which tools work best for different use cases.
