/model slash command (mid-session)
Switch between already-configured models without leaving a session:
By default, /model changes apply to the current session only. Add --global to persist the change to config.yaml (or set model.persist_switch_by_default: true to make every switch persist):
If you've only configured OpenRouter, /model will only show OpenRouter models. To add another provider (Anthropic, DeepSeek, Copilot, etc.), exit your session and run hermes model from the terminal.
On a --global switch, provider and base URL changes are persisted to config.yaml alongside the model. When switching away from a custom endpoint, the stale base URL is cleared to prevent it leaking into other providers.
From the official Hermes Agent CLI reference.
