If you've connected OpenRouter to n8n but only see a handful of models in the dropdown when building an agent or workflow, you're not alone — this is one of the most common points of confusion for new OpenRouter users. This article explains why this happens and how to control exactly which models appear in your n8n model selector.

Why Does n8n Show a Limited List of Models?

n8n dynamically loads the list of available models directly from the OpenRouter API at runtime. This means it only displays models that meet both of the following conditions:

  • The model is available to your OpenRouter account (i.e. you have access and sufficient credits/permissions).
  • The model has been explicitly selected in your Awesomate Limit Models settings for the OpenRouter provider.

If you haven't configured the Limit Models setting, n8n may fall back to a default subset of models, or show nothing at all. Adding your preferred models to the allowed list is the fix.

How to Add or Remove Models Using the Limit Models Setting

Follow these steps to control which OpenRouter models appear in your n8n dropdowns:

  1. In Awesomate, navigate to Settings in the left-hand sidebar.
  2. Select Chat from the settings menu.
  3. Locate the OpenRouter section and click Edit Provider.
  4. Find the Limit Models option. This is where you define your allowed model list.
  5. Search for and select the models you want to make available in n8n.
  6. Save your changes.

Once saved, return to your n8n workflow or agent and refresh the model dropdown — your selected models will now appear.

How Do I Know Which Models to Choose?

With hundreds of models available on OpenRouter, it can be hard to know where to start. Here are two resources to help you identify the best options for your use case:

  • LLM Stats — An independent AI leaderboard that lets you compare models by performance, speed, context length, and price. Useful for finding the best value model for your specific needs.
  • OpenRouter Rankings — The rankings page within your OpenRouter account, showing which models are most popular based on real usage data from millions of users. A great way to see what developers are actually using in production.

We recommend cross-referencing both resources — LLM Stats gives you objective benchmark data, while OpenRouter Rankings reflects real-world adoption and reliability.

Key Things to Remember

  • n8n does not cache a static model list — it pulls from the OpenRouter API each time, so changes to your Limit Models settings take effect immediately.
  • If a model is greyed out or missing, it may not be available to your OpenRouter account tier or region.
  • You can update your model list at any time by returning to Settings > Chat > OpenRouter > Edit Provider.
  • Keeping your list focused on a curated set of models makes it easier for your team to select the right model without scrolling through hundreds of options.
