# Hermes

> Install Prism's model-provider plugin in Hermes Agent.

## Copy for your agent

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
Follow https://docs.prisminference.com/guides/hermes to install and configure
the Prism provider. Preserve unrelated settings and never repeat my API key to
me or include it in your response.
```

If no key exists, follow [Agent signup](/guides/agent-signup) first.

## Install and configure

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
hermes config set PRISM_API_KEY "$PRISM_API_KEY" >/dev/null
hermes plugins install prismhq/hermes-prism-provider
hermes config set model.provider prism
hermes config set model.default deepseek-v4.1-flash
```

Select Prism as `prism:deepseek-v4.1-flash`.

## Verify

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
hermes config get model --json
hermes status
```
