How AI video is priced
Video models charge per second of output, and the rate depends on resolution and sometimes on audio. Veo 3.1 through Runway costs $0.20 per second without audio and $0.40 with audio, so sound doubles the price. Grok Imagine Video 1.5 is $0.08 per second. Google bills Gemini Omni 1.2 Flash by output video tokens, which works out to about $0.07 per second at 720p and $0.104 at 1080p with upsampling, and Google says one generation can run up to 15 seconds.
Minimum charges and per-video prices
Runway lists a minimum of 56 credits ($0.56) per generation for Aleph 2.0 and Seedance 2, so a one-second clip still costs $0.56. Z.ai prices CogVideoX-3 per video ($0.20), not per second. The calculator applies minimums and per-video prices automatically.
About the "via Runway" rows
Runway's developer API resells models from other companies and charges in credits at $0.01 each. We converted its credit prices to dollars. They are Runway's prices; check the model maker's own price if you can buy direct.
Not listed
The OpenAI pricing page we checked does not list video generation, and Google's Gemini pricing page lists Gemini Omni for video, so Sora and Veo are not priced directly here. Veo 3.1 appears through Runway.
