Seedance 1.0 Pro Fast API uses USD per million tokens for pricing, helping predict spend for high-volume workflows. Prices can vary by region, account tier, and provider updates, so treat listed rates as guidance and confirm the current rate card in your EvoLink account before forecasting spend.

Rate limits and concurrency caps are enforced at the account or project level and can change by plan. For the Seedance 1.0 Pro Fast API, monitor console limits, queue large batches, and use retries with backoff to keep throughput stable. This helps avoid spikes, reduce failed jobs, and keep delivery steady as demand rises.
