Hermes Opper

Opper, the EU-hosted AI gateway (700+ models behind one OpenAI-compatible API), as a model provider

How to install

Install it. Hermes asks for any API keys it needs (this one needs OPPER_API_KEY), then asks whether to turn it on.
hermes plugins install hermes-opper
Said no? Turn it on later:
hermes plugins enable hermes-opper
Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
