Hermes

Hermes Agent supports custom endpoints that implement the OpenAI Chat Completions API.

Create a Mixlayer API key

Create an API key in the Mixlayer console. See API Keys for more details on creating and managing keys.

Configure Hermes

Run the model setup wizard:

$
hermes model

Select Custom endpoint, then enter:

• API base URL: https://models.mixlayer.ai/v1
• API key: your Mixlayer API key
• Model name: qwen/qwen3.5-4b-free
• Context length: 131072
• API mode: Chat Completions

Hermes saves the provider, endpoint, and model in ~/.hermes/config.yaml.

Verify

Start a chat:

$

Inside the session, run /model to confirm that the Mixlayer model is selected.
