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:

arka thinking off
arka thinking low
arka thinking medium
arka thinking high
arka thinking

Arka stores the preference locally and adds it 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.
