One credit is one cent. Plans refill every month; packs top you up. Work is paid for before it runs, so a balance never surprises you.

Your plan governs your own work — and the work in every organization you own that has not bought a team plan.

Work in an organization is always paid for by its owner. A team plan buys a bigger allowance and more concurrency for everything done under that organization.

How billing works
1,000 credits cost $10. Every price in the product is shown in credits.
Each plan refills a free allowance for compute, AI and storage. It is spent before your own credits, and it does not accumulate.
A long-running machine — a computer, a simulation, a robot — prepays a two-minute block, then each next minute in advance. Your balance never goes below zero.
Create as many as you like. A free organization uses its owner's plan; a team plan raises the allowance for that organization only.
Bring an API key for a model provider and those calls are billed by the provider, not by us.
Upgrade, downgrade or cancel from the billing section of your account settings.
