Credit pack
Also known as: AI credit pack
A bundle of credits purchased one-time at a fixed dollar price. Larger packs offer a lower per-credit rate. Credits in a pack do not expire and are not auto-renewed.
In depth
What it means in practice
hilens.ai sells four credit packs: Starter ($0.99 / 100 credits), Plus ($5 / 1,000 credits), Pro ($24.99 / 5,000 credits), Studio ($99 / 20,000 credits). The per-credit price drops from $0.0099 at the trial-size Starter to $0.005 at Plus, then stays nearly flat — Studio's $0.00495 is only about 1% below the Plus rate, so larger packs buy a bigger balance rather than a steeper discount.
Unlike a subscription tier, buying a larger pack does not unlock additional features, faster generation, priority queues, or model access. All packs give the same product. The only thing that varies is the per-credit unit price.

Credit
On hilens.ai, a credit is the unit of payment for one increment of generation work. Models cost different numbers of credits per generation; credits are purchased in packs and never expire.
Pay per generation
A pricing model where you pay only when you click Generate, debited from a prepaid credit balance. Contrasts with subscription, where you pay a fixed monthly fee whether or not you generate.
Subscription credit
A credit included in a monthly subscription quota that expires when the next billing cycle starts. Distinct from a pay-per-generation credit, which never expires.
