Chief lets you dial intelligence up or down per task. Higher intelligence does more thinking, which costs more credits. Choosing the right level for each job is the simplest way to control your spend.

The intelligence levels and their cost

Chief billing - the intelligence levels and their credit cost
Open the Intelligence level menu in the prompt bar to pick a level. Each option shows its relative credit cost:
  • Auto (Automatic) — Baseline cost. Switches between Fast and Expert based on the complexity of your prompt, so simple prompts stay cheap and complex ones get more depth automatically.
  • Fast — Baseline cost. Prioritizes speed over depth.
  • Expert — Uses ~3x the credits. Deeper reasoning, but not as fast.
  • Deep Intelligence — Uses ~5x the credits. Deploys a fleet of long-running agents across LLMs that collaborate to get bigger jobs done. Available on paid plans.
💡 Tip: Leave Chief on Auto for day-to-day work. It uses Fast (baseline) when a prompt is simple and only escalates to Expert when the prompt warrants it — giving you depth when it matters without paying for it on every message.

How to change the level for a task

Chief billing - changing the intelligence level in the prompt bar
  1. In the prompt bar, open the Intelligence level menu.
  2. Select the level you want. Each row shows a credit-multiplier badge (for example “Uses ~3x the credits”) for the paid levels.
  3. Send your prompt — it runs at the level you selected.

FAQ

They’re approximate guides — Chief labels Expert as “~3x” and Deep Intelligence as “~5x” relative to baseline. Actual usage varies with the length and complexity of each task. Use them to compare levels, not to predict an exact charge.
Deep Intelligence is a paid feature. On a free plan the row shows an “Upgrade” prompt instead of selecting it. Upgrade to a paid plan to unlock it.
Prompts that mention agents require Deep Intelligence. Chief blocks the lower levels and offers a link to remove the agents and switch back to Auto if you’d rather run a cheaper level.
