This video by Nate Herk demonstrates a system that integrates OpenAI’s new O3 Mini reasoning model as an AI agent within an automation workflow. The tutorial builds a travel agent that pulls data from three Pinecone databases (resorts, flights, and activities), formats an HTML itinerary, and sends it via a Gmail tool. The video details prompt engineering, sequential tool calls, and includes a free downloadable workflow template available through his free Skool community.
