Pricing checked against provider documentation on . How we verify
The short answer
Veo 3.1 Lite is the cheaper option — roughly 2.4x less on a blended workload, and it suits cheap drafts during prompt iteration. Runway Gen-4.5 justifies its premium when you need runway's highest-fidelity output.
Google • Veo 3.1
$0.05 / $
/ video sec (input / output)
The cheapest route to generated video by a wide margin, and the reason Veo's tiering is genuinely useful: iterate prompts at three to five cents per second, then re-render only the approved shot on the full model. Silent output and preview status, with regional availability and fixed quotas to check.
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.
Input price
Runway Gen-4.5 is 2.4x the price than Veo 3.1 Lite on input tokens.
