AI video split into three niches in 2026: Sora owns realism, Veo owns audio and Google integration, Kling owns length and resolution. Here is how they compare on price and output.
Sora 2 (OpenAI)
Free in the Sora app with daily limits; ChatGPT Plus ($20) adds headroom and quality; Sora 2 Pro ships with ChatGPT Pro from $100. The API runs about $0.10 per second at 720p. Physics simulation and synchronized dialogue are the best in class.
Veo 3.1 (Google)
Native audio at every tier. Google AI Pro ($19.99) includes 1,000 Flow credits – roughly 50 Fast or 10 Quality videos monthly; Ultra from $99.99 unlocks 1080p without a watermark. The best value if you already pay Google for anything.
Kling AI (Kuaishou)
Kling 4.0 generates up to 30 seconds with native 4K output and Motion Control for choreography – features no Western rival matches. Standard $10 (660 credits), Pro $37 (3,000), Premier $92 (8,000), with commercial rights from Standard.
Our take
- Social clips and realism: Sora app (free) then Plus.
- Marketing video with sound: Veo via Google AI Pro $19.99.
- Long-form and 4K control: Kling Pro $37.
