[00:00] open AI is pushing back against deep seek with the latest reasoning model 03 mini O3 mini is similar to The Deep seek R1 model in terms of its performance and pricing but it also offers some very important features like structured outputs and function calling these features are critical for building AI agents O3 mini is also very easy to integrate into n8n so all we have to do is create a new workflow and we can go to Advanced AR and add an AI agent node

[00:32] let's add a chat model and in the list of nodes let's select the open AI chat model I'll select my open AI credentials and from the list of models you might not find the 03 model in this list as it's super new so thankfully all we have to do is change this from from list to buy ID and then we can replace this name with 03 mini 2025 0131 we can assign any tool that we want since this model does support function

[01:03] calling and this model also allows you to pass in a system message but I'm just going to test it out by clicking on chat we can then give it a complex problem to solve which brings back the reasoning as well as the final answer of course n8n also gives us access to some analytical data like what the chat model actually did and here we can see our input and finally the full output from the agent check out Che out my channel for more n8n and AI related content
