Choosing between MiniMax, Kling and Seedance for your API

Updated 2026-10-02

Which of these three should you build on? If someone answers that with a quality ranking, they are guessing: output quality depends on your prompts, subjects and tolerance for artifacts, and no benchmark substitutes for running your own set. What can be decided up front are the structural factors. This page lays out those, and then a cheap way to settle the rest empirically. It deliberately makes no claim that one family looks better than another.

Factor 1: input modes you need

Start with what your product must feed the model. The video docs describe three generation modes on one endpoint (text-to-video, image-to-video, reference-to-video), plus separate editing and extension features for specific models.

Where a cell says "check the model page", the claim depends on the exact Kling variant and host, and the model pages are the source of truth. If you need editing or motion transfer, that alone may decide it.

Factor 2: variant ladder

Every family has more than one tier, which matters for drafts and finals. MiniMax has minimax/h3, minimax/h3-max and minimax/h3-max-turbo. Seedance has several ids including 2.0, 2.0 Fast, 2.0 Mini and 2.5 in the catalog. Kling has multiple generations and tiers listed. A rich ladder lets you draft cheaply and finalize on a higher tier without changing code, so count the rungs that matter to you rather than the model count.

Factor 3: host breadth and failover

The same checkpoint is often sold by several hosts. More hosts means a wider price spread, more failover targets, and a lower chance that one provider outage stops your pipeline. Narrow host sets mean less room to route around trouble. The live price table shows host counts and the cheapest and priciest provider for the tiers on this site. Check the same figure for the alternatives at the time you decide, because it changes. Kling 4.0 was announced on 2026-09-28 but is not available on any host in the catalog yet, so do not plan around it.

Factor 4: integration cost (it is lower than you think)

Because all three go through the same POST /videos shape, the switching cost is mostly your own abstraction. Keep the model decision in config:

MODELS = {
    "draft": {"id": "minimax/h3-max-turbo", "modes": {"t2v"}},
    "main":  {"id": "minimax/h3",            "modes": {"t2v", "i2v", "ref"}},
    "alt":   {"id": "bytedance/seedance-2.0", "modes": {"t2v", "i2v", "ref"}},
}

def pick(mode, tier="main"):
    m = MODELS[tier]
    if mode not in m["modes"]:
        raise ValueError(f"{m['id']} not configured for {mode}")
    return m["id"]

Capabilities live in one table that you populate from the docs and model pages. Swapping or A/B testing a family is then a config edit. If you want automatic cross-model fallback rather than a manual switch, the docs describe a top-level models array that moves to the next model only after the first model's hosts are exhausted, for example "model": "minimax/h3", "models": ["bytedance/seedance-2.0"]. Be aware this changes the look of the output when it triggers, so log which model served each job.

Factor 5: price structure, not price

Do not compare a headline per-second figure. Compare the same resolution tier, the cheapest and priciest host, and your expected retry factor. Per-second pricing multiplies by seconds and by attempts, so a slightly cheaper model that needs more attempts per accepted clip can cost more overall. The live table on this site covers the MiniMax side. Note the platform fee is 2% on top of the host price on every model, so it does not distinguish between them.

Factor 6: how you will operate it

Look past the first integration to the running cost of ownership. How will you detect that a host has degraded? Do you need to keep output on a reviewed provider for data-handling reasons? Can you tolerate a different checkpoint serving traffic during an outage? Those answers shape whether you float across hosts, use an allow-list, or enable cross-model fallback, and they are easier to settle before launch than during an incident. The reliability guide covers the mechanics. If you run only one family today, keep the capability table above anyway, so that a second family is a config change rather than a rewrite.

How to settle the quality question yourself

1. Write 20 to 30 prompts and input images that look like your real traffic, including the awkward ones.
2. Run each through each candidate at the tier and resolution you would ship, same duration and aspect ratio.
3. Have the people who will accept the output rate them blind, without model names.
4. Record attempts per accepted clip, not just the best result.
5. Re-run the test when a family ships a new version.

Since all requests share one endpoint, the whole harness is a loop over model ids and about an afternoon of work. Create a key at videorouter.sh/signup and see the quickstart for the first call.
