The core of connecting the Hermes Agent to OpenRouter is to prepare the OpenRouter API key, and then select OpenRouter in the Hermes provider configuration. The official Providers documentation lists OpenRouter as a supported provider, making it suitable for beginners to quickly access multiple models.
Recommended steps
- Go to OpenRouter to create an API key.
- Run
hermes setup, select OpenRouter, and fill in the key. - If you configure it manually, write the corresponding OpenRouter key in
~/.hermes/.env. - After entering the
hermes, send a simple task verification.
How to choose a model
Beginners should first choose a model that is stable, contextually sufficient, and has good tool calling performance. Don't just look at the price, Hermes Agent needs a model that can plan and call tools, and a cheap model that is too weak may just say it won't do it.
When to use fallback
If the master model is often 429, 500, or temporarily unavailable, you can configure an alternate provider:model in provider routing to automatically switch when the main session fails.
In a word: OpenRouter is suitable for novices to quickly connect to multiple models, but choose a model that supports tool calls.
