Usage-based · about $0.14 / image · $0.135 reserved per request

Pricing

Billed by actual usage; there is no fixed unit price.

Typically about $0.14 per image at default settings.

Each request temporarily reserves $0.135; you are charged for actual usage, usually within a minute: any unused amount is released and any usage above it is charged to your balance, even if that takes it below zero; while your balance is below zero, new requests are paused until a top-up covers it.

Failed generations are not charged.
