Which should you choose?
Pick H3 Max for interactive video, rapid iteration and live formats. Pick Veo 3.1 Fast for narrative clips where native audio matters. Use the same prompt brief, aspect ratio and acceptance rubric across both.
Cost at production volume
At 1,000 ten-second generations, H3 Max is about $800 and Veo 3.1 Fast is about $1500, 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.
