Which should you choose?
Pick Runway Gen-4 Turbo for production workflows and predictable api billing. Pick Veo 3.1 for premium audiovisual output and cinematic prompts. Use the same prompt brief, aspect ratio and acceptance rubric across both.
Cost at production volume
At 1,000 ten-second generations, Runway Gen-4 Turbo is about $500 and Veo 3.1 is about $4000, 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.
