Which should you choose?
Pick Veo 3.1 Fast for narrative clips where native audio matters. Pick Wan 3 · 480p for cheap iteration and motion previsualization. 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 Wan 3 · 480p is about $500, 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.
