Every time you run a calculation, you'll use credits, similar to cell-phone minutes or a class pass at a gym. Jobs running on CPU machines charge 1 credit per minute. Jobs running on GPU machines charge 3 credits per minute or, if using H100 or H200 GPUs, 7 credits per minute.

For more details, see Rowan's full credit FAQ.

Yes, you can purchase more credits. Credits can be purchased by any user at any point via Rowan's billing page for 4¢ per credit. Purchased credits remain in your account for up to one year from the purchase date.
