Billing

Credits

Usage is priced in credits, where 1 credit = $0.005. Each model has a per-unit price (per image, per second of video, or per character of speech); the exact cost of a job is returned as cost_credits.

Estimating cost

Read a model's prices from /v1/models and multiply by units. For example a 6-second clip at 4 credits/second costs 24 credits ($0.12).

Refunds

Failed and canceled jobs are refunded automatically. Every credit movement is recorded in an append-only ledger, so balances always reconcile.
