More thinking costs more credits
Chief runs on credits, and your response mode is the biggest lever on how many a prompt uses. The deeper the mode, the more work Chief does — and the more credits that prompt consumes. Picking the right mode for the job keeps your credits going further.How each mode compares

- Fast — the lightest mode. Standard credit usage for a quick answer.
- Automatic — switches between Fast and Expert per prompt, so cost depends on which one it lands on for that request.
- Expert — deeper reasoning, so it uses roughly 3x the credits of a standard response.
- Deep Intelligence — runs a fleet of agents in parallel, so it uses roughly 5x the credits. It’s also a paid-plan feature.

FAQ
Why did one prompt cost much more than another?
Why did one prompt cost much more than another?
The mode is usually the reason. A Deep Intelligence prompt (~5x) or an Expert prompt (~3x) costs more than a Fast one. Adding an agent mention also pushes a prompt into Deep Intelligence, which raises its cost.
Are the multipliers exact?
Are the multipliers exact?
They’re approximate — the selector shows “~3x” and “~5x.” Actual usage varies with the size and complexity of the work, so treat the multipliers as a guide, not a fixed price.
I ran out of credits mid-task. What happens?
I ran out of credits mid-task. What happens?
Chief stops processing until credits are topped up. Refill your personal credits, or — for a shared project — have the project owner top up the project’s credits, since personal balance doesn’t apply to project work.
