# Thinking levels

> Choose a portable reasoning depth for models without native thinking controls.

Choose a portable reasoning depth for models that do not expose native
thinking controls:

```bash theme={null}
arka thinking off
arka thinking low
arka thinking medium
arka thinking high
arka thinking
```

The preference is stored locally and added as guidance to model prompts. Native
reasoning-capable models keep their own provider controls; this setting gives
ordinary chat/completion models a consistent user-facing depth selector.
