n8n Workflow Tutorials - OpenAI Fires Back at DeepSeek With a New Reasoning Model: o3-mini (n8n AI Agent)

In this tutorial, I’ll show you how to integrate OpenAI’s new reasoning model, O3 Mini, into n8n to build AI agents that support tool calling. A reasoning model that can call tools, like OpenAI’s O3 Mini, is a game-changer for AI agents because it allows them to take action beyond just generating text. Unlike models like DeepSeek R1, which are purely reasoning-based and lack built-in tool-calling capabilities, O3 Mini can interact with external APIs, databases, and applications in real time. 🚧 Start Building with n8n!
