Best AI Video Generation Tools (2026)
AI video generation matured fast in 2026 — 4K output, native synchronised audio and native portrait framing are now table stakes. OpenAI's Sora left the field entirely, with the app shut down in April 2026 and the API sunsetting that September, so the shortlist is led by Google, Runway and Kling. Here are the best.
Veo
Google Veo 3.1 generates 4K video with native synchronised audio in both landscape and native portrait, and it is bundled into Google AI Pro at $19.99/month rather than metered separately — the best quality per dollar in the category.

Frequently Asked Questions
What is the best AI video generator in 2026?
Google Veo 3.1 leads on value — 4K with native audio, included in Google AI Pro at $19.99/month. Runway Gen-4.5 tops the quality benchmarks and is the choice for professional editing workflows. Kling 3.0 is the strongest option for realistic motion, with native 4K since April 2026.
Is Sora still available?
No. OpenAI shut down the Sora app and web experience on 26 April 2026, and the Sora 2 API is scheduled for removal on 24 September 2026. Sora is no longer included with any ChatGPT plan. Use Veo 3.1, Runway or Kling instead.
How much does AI video generation cost?
Kling has a free tier with 66 credits a day and paid plans from $10/month. Runway gives 125 one-time free credits, then $12/user/month on Standard. Veo 3.1 is included with Google AI Pro at $19.99/month. Most platforms bill per second of generated video, so cost tracks length and resolution.
Can AI generate a full YouTube video?
Not in one pass. Current models generate clips of roughly 5-30 seconds, so a full video means generating several and assembling them in an editor. Native audio in Veo 3.1 and Kling 3.0 removes one step by generating sound with the footage.
