# Choose an intelligence setting
> Match the reasoning level to the job. Sessions use Auto, Normal, or Ultra. Runners use Normal or Ultra.
Intelligence is the reasoning level you assign to the job. Most jobs should start on **Normal**. Move to **Ultra** only when the work needs deeper reasoning.
## Sessions have three settings
| Setting | Use it for |
| ---------- | -------------------------------------------------------------------------------------------- |
| **Auto** | Let Runner choose for the task in front of it. |
| **Normal** | Attention briefs, pipeline checks, summaries, scheduling, and everyday work. |
| **Ultra** | Complex research, long documents, ambiguous comparisons, and work that needs more reasoning. |
New sessions start on **Normal** unless you change **Default intelligence** under **Settings**, then **Behavior**. That preference applies to new sessions on the device where you changed it.
You can still change the intelligence setting inside a session whenever the work changes.
## Scheduled Runners use Normal or Ultra
A scheduled Runner can't use **Auto**. Choose **Normal** for routine work and **Ultra** when the job needs the extra depth.
New Runners start on **Normal** unless you choose **Ultra** while setting one up.
Changing intelligence doesn't change tool permissions. **Ultra** doesn't let Runner read, change, or send anything **Normal** couldn't.
## Choose what sits behind each setting
Open **Settings**, then **Behavior** to choose the supported model behind **Normal** and **Ultra**. The available list can change as models are added or retired.
The session picker stays simple. It shows **Auto**, **Normal**, and **Ultra** rather than a separate exact-model list.
## Keep an eye on usage
**Ultra** uses more of your plan than **Normal**. That matters most for a Runner that runs often.
Use **Normal** for recurring triage and summaries. Move to **Ultra** when the result needs it. Simple.

## What's next?
Set **Normal** or **Ultra** for recurring work.
Intelligence controls how Runner reasons. Permissions control what it can do.
