Unclear It is not clear what decides whether the auto level is offered, so it may not appear for you yet.
What
The effort slider, reached from /effort, sets how much effort the model puts into its answers. It now has a keybinding action, effortSlider:adaptive, that switches an auto level on and off. A keybinding action is a named command you can attach to a key.
- While auto is selected, the slider track shows no marker.
- Confirming the slider with auto selected sets the level to auto.
- Auto is offered only when the current model supports it and another condition inside Claude Code is met.
- No key is attached to the action by default.
Why
Once available, you could choose adaptive effort from the slider and attach the action to a key of your own in your keybindings. Because no key comes attached, you will not come across the action by pressing keys.
