AI video generation in 2026: Veo, Kling, Seedance, Runway and what happened to Sora

The AI video field as of August 2026: Google Veo 3.1 leads on quality, Kling 3.0 on motion and price, Seedance 2.0 on benchmarks, Runway on control. Which model fits which job, and why teams use more than one.

When I first wrote about AI video in 2025, the story was a race between a handful of new models. In August 2026 the race has become a toolbox: native audio is standard, 4K is available, and most production teams route between two or three models depending on the scene. Here is who does what.

Google Veo 3.1: overall quality

Veo 3.1 is the model to beat for realism. It generates native 48 kHz audio with the video (dialogue, effects, ambience), outputs 4K, and has the strongest comprehension of cinematic language in prompts. It is the default for marketing concepts and anything a client will see first. It is also among the most expensive per second.

Kling 3.0: motion and price

Kuaishou's Kling has kept its position as the model for high-motion scenes and human performance. Kling 3.0 wins on price at around $0.10 per second, which is why it is the workhorse for social content at volume. Version 2.6 Pro is still widely used for its motion control.

Seedance 2.0: top of the leaderboards

ByteDance's Seedance 2.0 leads the text-to-video leaderboards in 2026, with HappyHorse, SkyReels, Kling 3.0, MiniMax Hailuo and Vidu clustered behind it. Seedance's particular strength is continuity: multi-shot sequences that hold characters and setting across cuts, which is what you need for anything longer than a clip.

Runway Gen-4.5: filmmaking control

Runway is still the professional's tool. Gen-4.5 offers the most direct control over camera, motion and style, video-to-video transformation, and custom-trained models for brand consistency. Slower and pricier than the Chinese models, and worth it when a human director is in the loop.

Sora 2: paused for consumers

OpenAI paused consumer access to Sora in early 2026. The Sora 2 model is still available to developers through API providers, and it retains the most distinctive cinematic style and good multi-shot narrative consistency. If you built a workflow on the Sora app, you have moved by now.

The fast tier

Hailuo 2.3 and Luma Ray Flash 2 generate clips in under 30 seconds. They are not the best-looking, but for storyboarding and rapid iteration they are what teams reach for before committing a scene to Veo or Runway.

What changed since 2025

Native audio went from Veo-only to standard across Veo 3.1, Kling 2.6/3, Sora 2, Seedance and LTXV 2.
Chinese models (Kling, Seedance, Hailuo, Vidu) now lead several benchmarks, and lead on price by a wide margin.
The open-source option moved from Alibaba's WAN to a broader field including LTXV, and runs on consumer GPUs.
Nobody uses one model. The common stack is a fast model to prototype, Kling or Seedance for volume, Veo or Runway for the hero shot.

What it means for a Danish company

Product videos, ads and social content that needed a production day now need an afternoon and a clear brief. The skill that matters is not the tool; it is knowing which model to send which scene to, and writing prompts in the language the models understand. That is a workflow problem, and workflows can be built.
