Which AI Video Model Is Best? Seedance vs Kling vs Veo

Every page ranking for this question was written by someone with a horse in the race. Model vendors reviewing themselves. API resellers. Affiliate sites regenerating the same listicle monthly. Search "Kling vs Seedance" and most of the first page is Kling and Seedance domains grading their own homework.

We run these models against real briefs, for clients, with deadlines. So here is the dated, sourced version, and then the part that actually matters: how you decide.

STILL IN MOST COMPARISON GUIDES Sora

OpenAI discontinued the Sora web and app experiences on 26 April 2026. The Sora API shuts down on 24 September 2026. No successor has been announced.

// source: OpenAI's own help documentation. checked 30 August 2026.

We're not going to dance on it. Sora mattered, it moved the whole field forward, and plenty of good work got made with it. But if you have anything running through that API you have a deadline, and most of the guides you'd search for right now will not tell you that.

If you were using Sora, here's the replacement

There is no single successor, because Sora was doing several different jobs. Match the replacement to the job rather than to the reputation.

Get your existing work out first. Before 24 September, not after. This is the only item on the list with a hard deadline attached.
Do not expect prompts to port. Every model reads a prompt differently, and a prompt tuned over months against one model is tuned to that model's habits. Budget for re-tuning rather than copy-paste.
Re-lock your references and seeds. Whatever you were doing to hold a face steady, you are doing it again from scratch on the new model.
Check whether audio comes with the picture. Native audio and audio laid on afterwards are different crafts and they read differently on screen. Not every model on the list has it.
Re-test before you commit a delivery. Move one finished shot across and compare it to the original honestly. That single test tells you more than any leaderboard.

Two more corrections while we're here

There is no Veo 4. Veo 3.1 is still the current Veo, and Google's frontier video work moved to Gemini Omni Flash in May 2026. There is no Midjourney V8 video model either, whatever the SEO blogs say. Midjourney's video model is still V1, from June 2025.

This is the real argument for working with people who do this daily. These are not obscure details. They are the three most basic facts about the three most famous names in the category, and much of what ranks for this question has them wrong.

We treat this like casting. Nobody asks which actor is best. They ask who is right for the part. Same discipline, same page in the process.

Seedance 2.5 ByteDance

Seedance 2.0 launched 12 Feb 2026. 2.5 generates 30 seconds in a single pass and extends twice from there.

Strength

Physical plausibility when several subjects are moving at once, and reference-driven work where you are feeding it stills and clips to match.

Watch for

ByteDance's own evaluation names multi-subject consistency, text rendering and occasional audio distortion as weak points.

How we cast it

Coverage. When we need many usable takes of a specified shot, this is the workhorse.

Kling 3.0 Kuaishou

Announced 5 Feb 2026. Fifteen seconds, native audio in English, Chinese, Japanese, Korean and Spanish, with per-shot control over duration, shot size and camera.

Strength

Structured multi-shot storyboarding, and holding text and logos legible inside the frame.

Watch for

The benchmark position is well below the marketing. Treat the storyboard control as the reason to use it, not the raw quality.

How we cast it

Sequences that have to cut together, and anything with a logo or product name that must stay readable.

Gemini Omni Flash 1.1 Flash Google DeepMind

Announced at I/O on 19 May 2026, generally available to developers 27 Aug 2026. Extends scenes to forty cumulative seconds, native audio, 4K upscale, SynthID watermarking.

Strength

Top of both no-audio leaderboards, and conversational multi-turn re-editing, which changes how a review cycle feels.

Watch for

Google's own model card names consistency across successive edits, complex motion and accurate text rendering.

How we cast it

Hero shots and anything a client will want to iterate on live in the room.

MiniMax H3 H3 MiniMax

Published 31 July 2026. Four to fifteen seconds, up to 2K, native stereo audio. Open weights on HuggingFace.

Strength

Sits at or near the top of the image-to-video boards, and is the strongest open-weights model available.

Watch for

Its community licence reportedly restricts open-weight use in several territories. We take legal advice before deploying weights on a client project.

How we cast it

Image-to-video, where a shot has to start from an approved still.

Luma Ray Ray3.2 Luma

Released 9 June 2026. Native HDR with 16-bit EXR export.

Strength

The only model on this list that hands a VFX department something it actually wants. EXR out means the shot goes into a compositing pipeline instead of dead-ending as an MP4.

Watch for

Character consistency across separate generations.

How we cast it

Anything with a finishing pipeline behind it, or a shot that needs real grading.

Runway Gen-4.5 Runway

Released 11 Dec 2025. Two to ten seconds, 720p, and no audio on the spec sheet.

Strength

Runway has quietly become the best finishing and editing environment rather than the best generator, and now serves other companies’ models alongside its own.

Watch for

If you came for a frontier generator, the generation numbers are no longer the reason to be here.

How we cast it

Editing, cleanup, and performance transfer, rather than first-pass generation.

Midjourney V1 video Midjourney

Still V1, from 18 June 2025. Image-to-video only, five seconds extending to twenty-one, 480p and 720p, no audio.

Strength

Preserves the palette, grain and lighting signature of the source still better than anything else. For illustrative and stylised work that matters more than resolution.

Watch for

Lowest resolution on this list, and there is no V8 video model regardless of what the blogs say.

How we cast it

Stylised and illustrative pieces where the look is the whole point.

FLUX 3 Video 3 Black Forest Labs

Generally available 4 August 2026. Up to twenty seconds, 1080p, native audio, keyframe control.

Strength

New enough that it has not settled onto the main leaderboards yet, which is exactly when a model is worth testing hard.

Watch for

Too new for anyone to have real production mileage. We are running it, not betting a delivery on it.

How we cast it

On the test bench.

// "watch for" is taken from the vendor's own model card wherever one exists.
// a weakness a company admits to in writing is the one you can trust.

Two public boards matter right now: Artificial Analysis and Arena. As of late August 2026, Artificial Analysis had Wan 3.0 leading text-to-video with audio, with Gemini Omni Flash and the MiniMax H3 variants close behind, and Kling 3.0 and Veo 3.1 well down the list. Arena, scored on a different anchor, had Gemini Omni 1.1 Flash on top.

The two boards use different Elo anchors and cannot be compared to each other. A number from one placed next to a number from the other is meaningless, and you will see that done constantly. You will also see figures quoted from a site running a different rating system on roughly a thousand votes, presented as if it were the same measurement.

Useful as a sanity check on marketing claims. Useless as a way to pick a model for a shot, because no board scores the thing you actually need, which is whether the same face survives across eleven takes.

Five questions, asked per shot rather than per project.

Does the shot start from an approved still? Then it is an image-to-video problem and the board you care about is the image-to-video board, which has a different leader.
Does anything in frame have to stay readable? A product name, a logo, a sign. Text rendering is the most commonly admitted weakness across the whole field, so this narrows the list fast.
Does the shot go into finishing? If it needs grading or compositing, you need a model that exports something a finishing pipeline accepts, which rules out most of them.
Does it need sound born with the picture? Native audio and audio added later are different crafts and they look different on screen.
Does a face have to match the last shot? This is where most projects break, and it is the single strongest argument for locking references and seeds before generating anything.

Answer those five and the model usually picks itself. That is the whole trick, and it is why we've never had a favourite.

Model casting is step two of how we work →

Which AI video model is best?

There isn't one, and any page that gives you a single winner is either selling that model or was written a while ago. As of August 2026 the leaderboards disagree with each other, they use different scoring anchors so they cannot be compared directly, and the ordering changes every few weeks. The useful question is which model is best for a specific shot, which depends on whether that shot needs multi-subject motion, legible text, a compositing-ready file, native audio, or a face that matches the previous take.

What happened to Sora?

OpenAI discontinued the Sora web and app experiences on 26 April 2026, and the Sora API shuts down on 24 September 2026. No successor has been announced. This matters if you are reading comparison guides, because a large amount of currently published advice still treats Sora as a live option and becomes wrong on that date.

What should I use instead of Sora?

It depends what you were using it for, because Sora was doing several jobs and no single model replaces all of them. For coverage with several subjects moving at once, Seedance. For sequences that have to cut together or anything with readable text on screen, Kling. For hero shots and live iteration in front of a client, Gemini Omni Flash. For shots starting from an approved still, MiniMax H3. For anything heading into grading or compositing, Luma Ray, because it exports files a finishing pipeline will actually accept.

Do my Sora prompts work on other models?

Not cleanly. Every model reads a prompt differently, and a prompt refined over months against one model is refined against that model's specific habits. Budget for re-tuning rather than copy-paste, re-lock your references and seeds, check whether the new model produces native audio, and move one finished shot across as a test before committing a delivery to it. Also get your existing work exported before 24 September, since that is the one item with a hard deadline.

Is there a Veo 4?

No. As of 30 August 2026 Veo 3.1 is still the current Veo, with a Lite version and upscaling added on 3 April 2026. Google's frontier video work now sits under Gemini Omni Flash, announced at I/O on 19 May 2026, with Gemini Omni 1.1 Flash reaching general availability for developers on 27 August 2026.

Which model do you use at Talentless AI?

All of them, and the choice is made per shot rather than per project. Model casting is a step in our process the same way casting an actor is. A sequence can easily use three different models: one for the multi-subject coverage, one for the shot with a product name that has to stay readable, and one for the hero shot that goes into finishing. Being tied to a single model means bending the work to fit the tool.

Should I pick one model and standardise on it?

For an internal team learning the craft, standardising on one model is a reasonable way to build fluency, and we teach it that way. For production work it costs you. Every model on the current board has a documented weakness, usually admitted by the company that built it, and standardising means inheriting that weakness on every shot you deliver.

How do you keep up with this?

We test continuously and we date everything. This page carries a verification date for that reason. Between February and August 2026 a flagship model was discontinued, two frontier models shipped, the leading open-weights model changed hands, and the top of the main leaderboard changed several times. Anything written about this without a date on it should be treated as undated.

Are there legal issues with AI video models?

Yes, and they are live. The Disney, Universal and Warner Bros. case against Midjourney, covering both image and video, survived a motion to dismiss in May 2026. A class action was filed against Twitch and Amazon on 20 August 2026 over training video models on creator streams. The NO FAKES Act cleared Senate Judiciary in June 2026 and is not law. We handle rights and provenance as part of delivery rather than leaving it for a client's legal team to discover later.
