Every few days, another AI model becomes worth trying. One gets better at coding. Another becomes much cheaper. Another suddenly handles huge files or works better with agents. After a while, the annoying part is not finding a good model. It is having another account, another API key, another payment setup, and another workflow built around it.
That is why I picked OpenRouter as the third tool in this series.
We started with The n8n 101 Guide, where we learned how to connect tools and build AI workflows. Then we moved to The Ollama Guide, where we learned how to run AI models locally.
OpenRouter is different. It is one of those tools that looks boring for five minutes, then suddenly makes a lot of modern AI work much easier.

OpenRouter says it now handles more than 10 trillion tokens every day, across 400+ models, for more than 10 million developers and companies. Stripe agreed to acquire the company in August 2026.
But the big number is not why I think this tool matters.
The useful part is very simple.
You can have Claude, GPT, Gemini, DeepSeek, Qwen, Llama and hundreds of other models available behind one account and one API.
You do not need to build your app again every time you change the model.
You change the model name.
That is the whole idea.
Think of it like this:
Your workflow
↓
OpenRouter
↓
The AI model you want
Or, if you do not want to choose the model yourself:
Your workflow
↓
OpenRouter
↓
OpenRouter chooses the model
This becomes very useful once you are working with agents, coding tools, automations, research systems, customer support, document processing or anything that makes many AI calls.
