Kling 4.0 isn't out yet: How to choose between three AI video tools

AI tools that generate video from text or images keep getting better. Several comparisons of Kling, Seedance and Wan are now available. There is one important catch: according to guides from the service WaveSpeed (September 27, 2026), Kling 4.0 has not been released yet. The figures cited for it are rumors and are not confirmed.

Seedance 2.5: long shots

Seedance 2.5 is available now. It produces clips of 4 to 30 seconds at up to 4K, a very sharp resolution. It can use up to 30 reference images, meaning images you give it so that characters or products look consistent. It also has features for editing and extending clips.

The guide recommends it for long, continuous shots, such as a product demo in a single take, and for projects with many reference images.

Wan 3: many kinds of input

Wan 3.0 is also available. It produces clips of 2 to 30 seconds, but only up to 1080p (standard HD). In return, it can accept up to 10 images, 5 videos and 5 audio clips as references.

According to the guide, it is the best fit if you want to mix different kinds of material or edit and extend existing footage.

Kling: multi-shot scenes

The current Kling 3.0 produces clips of 3 to 15 seconds and has a separate 4K version. Its strength is scenes with up to six different camera setups in a single prompt, plus a system for reusing the same character across multiple videos.

Kling 4.0 is expected to produce clips longer than 15 seconds and offer better consistency, but that is not confirmed.

What does this mean for you?

If you need long, uninterrupted shots, look at Seedance 2.5 or Wan 3. If you want to make a short film with multiple shots and a recurring character, Kling 3.0 is a better bet. If the final result needs to be in 4K, that points to Seedance or Kling.

Keep in mind that the guides were written by a service that offers the models itself. So try the tools with your own examples before you choose. The guides give the same advice for when Kling 4.0 is released.
