Can You Run Seedance 2.5 Locally? Open Source Status

No. You can’t run Seedance 2.5 locally. Seedance 2.5 is a closed, proprietary video model from ByteDance. ByteDance hasn’t published its weights or a model license, so there’s nothing to download, nothing to load into ComfyUI, and no GPU you can run it on yourself. Every legitimate way to use Seedance 2.5 calls ByteDance’s servers, either directly or through a platform like Krea.

This post covers what’s actually on Hugging Face and GitHub under the Seedance name, why “Seedance 2.5 download” and “mod APK” offers aren’t what they claim to be, and what to do if you need a hosted workflow or a model you can truly run on your own hardware.

Key takeaways

• Seedance 2.5 isn’t open source. No weights or model license have been released, so it can’t be run locally or offline.
• Hugging Face and GitHub “Seedance” projects are API clients or wrappers. None of them contain the model.
• “Seedance 2.5 download” and mod APK files aren’t the model. At best they’re wrappers. At worst they’re malware.
• To use it from scripts or node pipelines, call it through an API. Krea’s API exposes Seedance 2.5 with one key.
• If you need weights on your own hardware, use an open-weight model such as LTX-2.3 or Wan 2.1/2.2 instead.

Is Seedance 2.5 open source?

No. As of October 2026, ByteDance hasn’t released weights for Seedance 2.5, or for any earlier Seedance version. ByteDance’s Seed team does publish some research models on Hugging Face and GitHub, but Seedance isn’t one of them. Seedance is offered as a service: in ByteDance’s own consumer apps, and to developers through ByteDance’s cloud APIs (BytePlus ModelArk internationally, Volcengine in China).

The model is only offered as a service because it’s a large commercial product. ByteDance sells access to it and keeps the weights in-house. That could change, but there’s no public sign that an open release is planned.

What about Seedance on Hugging Face or GitHub?

Search Hugging Face or GitHub for “Seedance 2.5” and you’ll find projects with the name. Look inside and they fall into two groups:

• API clients and SDK wrappers that send your prompt to a hosted Seedance endpoint and need an API key.
• Demo apps and Spaces that call a hosted service in the background.

None contain model weights, and none run Seedance on your own GPU. If a repo says it does, check for weight files and a license. You won’t find either.

Can you use Seedance 2.5 in ComfyUI?

Not as a local model. ComfyUI can’t load Seedance 2.5 because there’s nothing to load. Some ComfyUI nodes send requests to a hosted Seedance API: the node sends your prompt and inputs to a server and brings the video back. That works, but the model still runs in the cloud, you still pay per generation, and you still need an internet connection.

If you want Seedance 2.5 inside an automated pipeline, the simplest route is a direct API call. Seedance 2.5 API Access: Guide, Features, Code Examples walks through calling it from code with a Krea API key. The same key covers the rest of Krea’s video models, so you can switch models in a script without setting up a new provider.

If you like node-based workflows but don’t want to host anything, Krea Nodes lets you chain Seedance 2.5 with image models, upscalers and other video models in the browser.

Is there a Seedance 2.5 download or mod APK?

Be careful here. Because Seedance 2.5 has no released weights, any site offering a “Seedance 2.5 download,” a “Seedance 2.5 local model,” or a “Seedance 2.5 mod APK” with unlimited free generations is offering one of these:

1. A wrapper around a hosted API, often reselling credits or using someone else’s account.
2. A different, smaller open model relabeled as Seedance.
3. Malware or adware using a popular model name as bait.

None of these is the model. Unofficial APKs in particular can ask for broad device permissions, and there’s no legitimate reason a video model app needs them. If you want to try Seedance 2.5, use a known platform. Is Seedance 2.5 Free? covers what’s free and what isn’t.

How to actually use Seedance 2.5

There are two practical routes:

• In the browser. On Krea, Seedance 2.5 is in the video workspace: pick it from the model list, write a prompt, add references, and generate. It’s included on the Pro plan and above. See How to Use Seedance 2.5 for a step-by-step walkthrough.
• Through an API. Use ByteDance’s own developer platform, or a single Krea API key that also covers other video models.

Both give you the full model: 4 to 30-second takes, 480p to 1080p, six aspect ratios, native audio, start and end frames, and up to 30 image, 10 video and 10 audio references.

Every way to run Seedance 2.5, compared

Two of these routes give you no Seedance at all, and the rest all run on the same hosted model. The real choice is how you want to drive it: by hand in a browser, from a node graph, or from code. If you’re comparing costs, our Seedance 2.5 pricing guide has per-second rates and real spend from test runs.

Want something you can run on your own hardware? Open-weight alternatives

If you need local control, such as offline work, custom fine-tuning, LoRAs, or keeping footage on your own machines, use an open-weight video model instead:

• LTX-2.3 from Lightricks is a 22B audio-video model with weights on Hugging Face under the Apache 2.0 license. It generates synchronized sound and runs locally, if you have a high-end GPU.
• Wan 2.1 and Wan 2.2 from Alibaba are released as open weights and are widely used in ComfyUI workflows, including with LoRAs.

Expect trade-offs. Running a 20B+ video model at good speed needs serious hardware, and you take on setup, updates and render time yourself. On quality, long takes and reference handling, Seedance 2.5 is still ahead of what you can run at home today.

You can also try these models on Krea without installing anything. LTX-2.3 is on Krea, along with several Wan models, so you can compare them with Seedance 2.5 using the same prompt before deciding whether to set up a local workflow.
