For task-specific direct endpoints, Hermes uses the task's configured API key or `OPENAI_API_KEY`. It does not reuse `OPENROUTER_API_KEY` for those custom endpoints.
## Fallback Model (config.yaml only)
## Fallback Providers (config.yaml only)
The primary model fallback is configured exclusively through `config.yaml` — there are no environment variables for it. Add a `fallback_model` section with `provider` and `model` keys to enable automatic failover when your main model encounters errors.
The primary model fallback chain is configured exclusively through `config.yaml` — there are no environment variables for it. Add a top-level `fallback_providers` list with `provider` and `model` keys to enable automatic failover when your main model encounters errors.
```yaml
fallback_model:
provider: openrouter
model: anthropic/claude-sonnet-4
fallback_providers:
- provider: openrouter
model: anthropic/claude-sonnet-4
```

See [Fallback Providers](/docs/user-guide/features/fallback-providers) for full details.
