-| 47 | `/effort [low\|medium\|high\|xhigh\|max\|auto]` |  | Set the model effort level. Available levels depend on the model and include `low`, `medium`, `high`, `xhigh`, and `max` (session-only). Without an argument, opens an interactive slider to pick the level. `auto` resets to the model default. Takes effect immediately without waiting for the current response to finish |

Available levels depend on the model and include `low`, `medium`, `high`, `xhigh`, `max` (session-only), and `ultracode` (combines `xhigh` reasoning with automatic workflow orchestration; session-only).
