Pricing checked against provider documentation on . How we verify
The short answer
Runway Gen-4.5 is the cheaper option — roughly 3.3x less on a blended workload, and it suits runway's highest-fidelity output. Veo 3.1 justifies its premium when you need best all-round generated video.
Runway • Runway Gen-4
$0.12 / $
/ video sec (input / output)
The quality tier of the Runway line at 12 credits per second, roughly two and a half times Turbo. Worth it only where the fidelity gain is visible in the final cut — Runway's real advantage is the surrounding editorial toolset, including the Aleph video-to-video editing model, rather than the generator alone.
Google • Veo 3.1
$0.40 / $
/ video sec (input / output)
The strongest general-purpose video model available through a stable API: 4K output, native audio, strong prompt adherence, and controls for character and style consistency, plus extension and seamless transitions for sequences longer than one clip. Google lists a retirement date of November 2026 or later, so track the successor.
Input price
Veo 3.1 is 3.3x the price than Runway Gen-4.5 on input tokens.
