Which should you choose?
Pick Seedance 2.0 for complex prompts, references and multi-shot output. Pick Seedance 2.5 for production-grade reference control and longer takes. Use the same prompt brief, aspect ratio and acceptance rubric across both.
Cost at production volume
At 1,000 ten-second generations, Seedance 2.0 is about $3034 and Seedance 2.5 is about $4730, before retries and ancillary fees.
Method
We prioritize first-party API pricing and explicitly label resolution and audio. Speed descriptions are directional unless the provider publishes a repeatable benchmark.
