Pay for the generation you run.

How design credits work

Packs are US$8 for 800 credits, US$20 for 2,000 credits, and US$50 for 5,000 credits. 1 credit = US$0.01. Checkout charges the pack once. Credits are issued after payment succeeds and do not expire. There is no subscription, no renewal, and no free trial. New accounts start at 0 credits. Existing preview accounts keep their current allowance.

Each generation is charged from the AI tokens it actually used, priced at the fixed peak rate, multiplied by 3, and converted to credits. A typical generation is about 100–300 credits. Server CAD time is not charged, and the rate does not change with the time of day. There is no per-generation credit cap. Clarification questions, viewing, downloads, and failed generations cost 0 credits. If you cancel a generation, you are charged only for usage that already occurred. A balance below 300 credits cannot start a generation. One generation freezes at most 700 credits, and unused frozen credits are returned when it ends. Complex or unsupported requests may be declined. The service does not promise unlimited successful models.

Credits are a service allowance, not withdrawable money. There are no automatic overages. This phase generates one CAD model from a sentence, with an optional reference image. You can view it in 3D, play a motion demonstration, and download STEP or STL. It does not include manual editing, AI modification, or import-and-edit.
