Build Anything with OpenAI’s New OSS Models (n8n Agents)
OpenAI just released two massive open-source GPT models — GPT-OSS-20B and GPT-OSS-120B — and you can run them locally for free.
In this video, I’ll walk you step-by-step through setting them up with Docker and Ollama, connecting them to n8n agents, and building real automations — all without paying for API calls.
You’ll learn how to:
• Install & run the GPT-OSS models locally
• Alternatively, learn to setup open router to use any model
• Connect them to n8n with tool-calling workflows
• Test basic chat prompts and advanced automation
• Explore the strengths & limitations of these new models
Whether you’re into AI automation, open-source AI, or n8n workflows, this guide will help you get started fast.
