Is Seedance 2.0 Open Source? What You Can Download

No. Seedance 2.0 is not open source, and no version of it has published weights. ByteDance ships it as a commercial model behind an API, which is why you will not find it on Hugging Face under any official account no matter how the search results look.

That answer takes one line, but the search results around it are genuinely misleading, so the rest of this page shows the evidence. ByteDance does open-source a lot of models, including video ones, which makes the absence of Seedance meaningful rather than incidental. And if what you actually need is downloadable weights for video generation, there is a real answer to that, with benchmark numbers attached.

TL;DR

• Seedance 2.0 has no public weights. It is API-only, through BytePlus internationally and Volcano Engine in mainland China.
• ByteDance's official Hugging Face org exists and is active, publishing SDXL-Lightning, Hyper-SD, AnimateDiff-Lightning, LatentSync and the Ouro language models^[1]. Seedance is not among them.
• The "Seedance" repos you find are personal accounts, with download counts in the single digits^[2]. None are ByteDance.
• For actual open weights, the Wan family is the serious option, with Wan2.1 and Wan2.2 published under the Wan-AI org and downloads in the six figures^[3].
• Wan also has independent benchmark standing, ranking third on Artificial Analysis text-to-video^[4], so this is not a consolation prize.

What ByteDance does open-source

This is the part that makes the answer credible. ByteDance is not a company that avoids open weights. Its verified Hugging Face organization publishes actively, and several of its releases are widely used^[1]:

Note the last row. ByteDance has open-sourced a text-to-video model. It simply is not Seedance, and AnimateDiff-Lightning is a different and much older piece of work. The company draws a line between research artifacts it releases and commercial models it sells access to, and Seedance 2.0 sits firmly on the commercial side.

That is also consistent with how it is distributed. The model is served through BytePlus and Volcano Engine as API endpoints with IDs like seedance-2-0-260128^[5], priced per minute of output. Models with published weights do not need per-minute API pricing.

What those "Seedance" repositories actually are

Search Hugging Face for Seedance and you get results, which is where people get misled. Looking at who published them settles it^[2]:

Every one is an individual user account, not the ByteDance organization, and the download counts are single digits. Compare that against SDXL-Lightning's 99.8k under the official org. These are name-squatted or placeholder repositories, and none of them contain Seedance model weights, because those weights have never been released to squat on.

The same reasoning applies to GitHub results. Repositories carrying the name are third-party wrappers, demos, or unrelated projects that merely match on "seed." Checking the publishing account is the fastest way to sort real from noise, and for Seedance the official account has nothing to find.

Checking an open-source claim in under a minute

This pattern repeats across every commercial model that gets rumored open, so the check is worth having on hand. Four signals, in the order that settles it fastest:

1. Who published it. A verified organization account, not an individual. Hugging Face marks company orgs, and a real release lives under the company's own namespace.
2. Are there weight files. Open the Files tab and look for .safetensors or .bin at model scale. A repository holding only a README, a config, or a link out is not a release.
3. What the download count says. Genuine open weights accumulate thousands of downloads quickly. Single digits after months means nobody found anything usable in it.
4. How it is priced elsewhere. Per-minute or per-token API pricing on a vendor platform is the strongest tell that weights were never released, because there would be nothing to meter if they had been.

Applied to Seedance 2.0, all four point the same way, and no single ambiguous result changes that.

If you need open weights, use Wan

This is the useful part for anyone whose actual requirement was self-hosting rather than Seedance specifically. Alibaba's Wan family publishes real, downloadable video weights under the Wan-AI organization, and the download counts show genuine adoption^[3]:

The 1.3B and 5B variants matter if you are self-hosting on consumer hardware, since the 14B models want serious VRAM. Both text-to-video and image-to-video are covered, which is more than most open video releases offer.

Wan is also competitive rather than a fallback. On the Artificial Analysis text-to-video arena, Wan2.7 ranks third with an Elo of 1,165, behind Gemini Omni Flash and Seedance 2.0 and ahead of Kling 3.0 Pro and Veo 3.1^[4]. One caveat on that comparison: the benchmarked 2.7 release is newer than the 2.1 and 2.2 weights currently published on Hugging Face, so what you can download is not the exact build that scored 1,165.

Using Seedance 2.0 without weights

If the open-source question was really about access rather than self-hosting, the practical routes are unchanged. BytePlus ModelArk carries the official API internationally, with per-minute pricing and region-scoped endpoints. Third-party studios call that API for you and charge on their own terms.

That second option is what this site is: an independent third-party platform, not affiliated with ByteDance, providing browser access to the model. You can generate from a prompt at seedance2.so/text-to-video or animate a still at seedance2.so/image-to-video, with free credits on signup to test output before paying.

FAQ

Is Seedance 2.0 open source?

No. Seedance 2.0 has no published weights and is distributed only as a commercial API. ByteDance's official Hugging Face organization is active and publishes other models, but no Seedance release appears there^[1].

Is Seedance 2.0 on Hugging Face?

Not officially. Searching returns repositories from personal accounts with single-digit download counts^[2], none of which belong to the ByteDance organization and none of which contain model weights.

Is there a Seedance 2.0 GitHub repository?

Nothing official that contains the model. Repositories using the name are third-party API wrappers, demos, or unrelated projects matching on "seed." The reliable check is whether the publishing account is ByteDance, and for Seedance weights it never is.

What is the best open source alternative to Seedance 2.0?

The Wan family from Alibaba. Wan2.1 and Wan2.2 publish downloadable text-to-video and image-to-video weights ranging from 1B to 14B parameters^[3], and the line ranks third on the Artificial Analysis text-to-video arena^[4].

Can I run Seedance 2.0 locally?

No, because there are no weights to run. Generation happens on remote servers through the official API or a platform built on it. If local inference is a requirement, an open-weight model such as Wan is the only workable path.

Has ByteDance open-sourced any video model?

Yes, AnimateDiff-Lightning, a text-to-video model with about 11.8k downloads on its official Hugging Face organization^[1]. It is unrelated to and considerably older than Seedance, which shows the company distinguishes research releases from commercial products.

Will Seedance 2.0 be open-sourced later?

There is no announcement indicating that. The model was released in February 2026 as a commercial product^[6] and is priced per minute through the official platforms, which is not how a model headed for open release is usually distributed. Treat any claim otherwise as unverified until an official source says so.

How do I use Seedance 2.0 if it is not open source?

Through the official BytePlus API if you are building an integration, or through a third-party browser studio if you just want output. Both call the same upstream model, and the difference is how much setup you do yourself.

Sorting downloadable from purchasable

The short version holds up under scrutiny: Seedance 2.0 is not open source, has never had published weights, and is sold per minute through official API platforms. What makes that conclusion solid rather than an assumption is that ByteDance clearly does open-source models, including a text-to-video one, and Seedance still is not among them. If your requirement was weights you can download and run, Wan2.1 and Wan2.2 are the credible answer and they benchmark well. If your requirement was just using the model, the API and the platforms built on it are the whole list, and neither one asks you to care whether Seedance 2.0 is open source.
