I attempted to use the o3-mini model via OpenRouter last night, and it worked successfully while my OpenAI API access was still at Tier 2. However, today I am consistently encountering errors. Has anyone else experienced this issue?

Hi Nate, Which apps are you currently using to record your video screen? Thanks for sharing! 😄

Want to dive deeper into this build and discuss how to enhance it? Join AIS+ 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.
