DOCUMENTATION

Choose the Right Workflow

Use the exact model alias issued for the product you intend to call. The video products share task endpoints, but their inputs, outputs and billing models differ.

Native generation and Production are separate products

Native Seedance 2.5 supports 480p, 720p and 1080p. Production delivers AI-enhanced 1080p, 2K or 4K video. Do not treat Production 2K or 4K as native Seedance 2.5 inference.

The name “Production” identifies the composite video product. It does not by itself indicate that a feature is enabled in a live customer environment.
