Which should you choose?
Pick Veo 3.1 Fast for narrative clips where native audio matters. Pick Seedance 2.0 for complex prompts, references and multi-shot output. Use the same prompt brief, aspect ratio and acceptance rubric across both.
Cost at production volume
At 1,000 ten-second generations, Veo 3.1 Fast is about $1500 and Seedance 2.0 is about $3034, 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.
