No. Every generation incurs a processing cost to Carveco, so credits are always required. In Text to Relief, spending 1 credit generates 4 sample images from your text prompt. These are not free previews, but actual generated images you can choose from. If you want to turn one of those images into a relief, that step costs an additional 5 credits. In Image to Relief, each relief generation costs 5 credits directly. This system ensures transparent pricing while covering the real processing costs of generating high-quality results.
