Prices are per second of generated video. Taxes, volume discounts and failed generations are not included.

How is AI video priced?

Most video APIs charge per second of generated video. Higher resolutions and native audio cost more, so a 1080p or 4K clip can cost several times a 720p clip.

What is the cheapest AI video model?

It depends on the resolution. Light models such as Veo 3.1 Lite, Grok Imagine and Wan start around $0.05 per second, while premium models at 4K can cost $0.40 per second or more.

Is Sora included?

No. OpenAI removed the Sora 2 video models from its API on September 24, 2026, so Sora is no longer available to developers.
