MiniMax H3 vs Seedance 2.0 vs Kling 3.0 vs Veo 3.1

The 2026 landscape changed fast

The AI video model race looks very different in August 2026 than it did six months ago. MiniMax's H3 launched on July 31, 2026 and immediately became the model everyone is talking about: native 2K output, stereo audio generated in the same pass, reference control across up to 12 files (9 images + 3 video + 3 audio), and an open-weights release — at a per-second price roughly a quarter of Sora 2 Pro. Meanwhile OpenAI has begun decommissioning Sora 2 (web app shut down in April 2026, API sunsetting in September), Kling 3.0 still leads on raw resolution and price, and Veo 3.1 remains the benchmark for cinematic audio and color.

For anyone deciding which model to generate with, this is great — more choice, lower prices, better output. But it creates a second, growing problem: when you see a video online, how do you know which model made it? That question is where official verification matters, and the models are not equal on that front.

The four models at a glance

Rough numbers from public pricing and specs as of August 2026 — treat them as a starting point, not a quotation. The practical takeaway: H3 and Seedance both offer deep multimodal control, Kling is the value/resolution play, and Veo is the premium cinematic option.

What generation costs — and what verification costs

The same per-second pricing that makes these models attractive also makes the verification question worth asking. Generation is not free, and it is not cheap at scale — which is exactly why knowing what a video was made with matters before you license, moderate or publish it.

Generating is a paid, per-clip cost on every model. Verifying is free on exactly one of them: Seedance, through the official ModelArk artifact verification API. The other current front-line models have no public verification API at all, so a "which model made this?" question about an H3, Kling or Veo clip currently has no official answer — the closest you can get is checking whether it was not Seedance, and even a negative result has limits (re-encoding can remove the signals the API relies on).

Price sources: MiniMax H3 rates are from the official MiniMax pay-as-you-go pricing (2K billed at $0.13 per second, 768P at $0.08 per second). Seedance, Kling and Veo figures are approximate per-clip estimates from public pricing as of August 2026 and can change without notice — verify before budgeting.

The question nobody compares: who can verify a video?

Every AI video model has a "how to generate" story. Almost none have a "how to verify an existing video" story — and that asymmetry is exactly what this site exists for.

That is the practical gap behind this page. MiniMax H3 is the hottest model of the moment, but right now there is no official API to check whether a video was made with H3, Kling or Veo. Seedance is the one model in the current front line with an official, queryable verification API — and this site wraps it into a free checker.

Check a video for official Seedance signals

If a video might be Seedance underneath — for example, a clip from a platform like Renoise, Higgsfield or Dreamina that uses Seedance as a model option — you can verify it directly against the official ModelArk API. Upload the file or paste a public link below, and the service checks both official endpoints (Volcengine and BytePlus) in parallel, returning the verdict and model version in one to two minutes.
