Is Wan 3.0 Open Source? What Is Available and Why Wan 2.2 Is

The short answer is no: Wan 3.0 is not open source as of August 18, 2026. Alibaba has made the model available as an invite-only hosted service, but it has not published Wan 3.0 model weights, inference code, or an open license. Wan 2.2 is different. Its code and weights are publicly available under the Apache 2.0 license.

That distinction matters if you are deciding whether to use the latest hosted model, build on an open model locally, or wait for a future release. This guide explains what “Wan 3.0 open source” currently means in practice and where Wan 2.2 remains the open option.

The quick answer: Wan 3.0 is available, but it is not open source

Wan 3.0 has been released as a service, not as an open-source model package. The official Qwen platform changelog lists wan3.0-video on August 6, 2026 as an invite-only All-in-One video model. It supports text-to-video, image-to-video, first-and-last-frame, and reference-to-video workflows, but the listing does not announce downloadable weights or source code.

The official Wan GitHub organization provides another useful check. As of August 18, its public repositories include Wan 2.1, Wan 2.2, Wan-Dancer, Wan-Animate-2, Wan-skills, and a Diffusers fork. There is no official Wan 3.0 repository.

So, “released” and “open source” are not interchangeable here. You can explore the hosted model on the Wan 3.0 AI video generator, but you cannot currently download the official Wan 3.0 weights and run the same model on your own hardware.

What would need to exist for Wan 3.0 to count as open source?

For a video model, a hosted web interface or API is access, not open-source distribution. A credible open release normally gives developers enough artifacts and permissions to inspect and run the model outside the provider's service.

That usually includes:

• downloadable model weights or checkpoints;
• inference code and configuration files;
• a license explaining permitted use, modification, and redistribution;
• installation or deployment documentation.

Wan 3.0 currently does not have that official release package. This does not mean the service is unavailable, and it does not predict what Alibaba may publish later. It means only that the evidence required to call Wan 3.0 open source is not available today.

Be careful with third-party pages that label Wan 3.0 “open source” without linking to official weights, code, and a license. A product name, a demo, or an API model ID does not establish an open release.

Why Wan 2.2 is open source

Wan 2.2 has the release artifacts that Wan 3.0 currently lacks. The official Wan 2.2 GitHub repository states that the team released its inference code and model weights on July 28, 2025. The repository links to downloadable checkpoints on Hugging Face and ModelScope, includes local inference instructions, and licenses the models under Apache 2.0.

The open Wan 2.2 lineup includes text-to-video, image-to-video, and combined text-image-to-video variants. Additional public releases cover speech-driven video and character animation. Hardware requirements vary by model, so “open” does not necessarily mean easy or inexpensive to run locally.

If you want to see what the model can do before configuring a local stack, the Wan 2.2 video generator offers a browser-based route. Developers who need local inference, inspectable code, or a foundation for custom tooling should start from the official repository and review the license for their own use case.

Wan 3.0 vs Wan 2.2: the practical open-source difference

This comparison is about release and deployment, not a claim that one model produces better video in every situation. Wan 3.0 is the route for trying the new hosted workflow. Wan 2.2 is the route when openness, local control, or integration access is the deciding factor.

Which Wan model should you choose?

Choose Wan 3.0 when your priority is using the latest available creation workflow without managing a local inference environment. The Wan 3.0 page lets you review its current inputs and generation options in the browser.

Choose Wan 2.2 when you need to download official weights, inspect the inference implementation, build a local workflow, or test modifications. You can begin with the official repository or use the Wan 2.2 page to evaluate the model through a simpler hosted interface first.

The trade-off is straightforward: Wan 3.0 offers access to the newer hosted model, while Wan 2.2 offers the open release. The right choice depends less on the version number than on whether your workflow needs convenience or control.

Could Wan 3.0 become open source later?

It could, but there is no confirmed open-source release to rely on today. Alibaba previously published code and weights for Wan 2.1 and Wan 2.2, so a future Wan 3.0 release is possible. Past releases, however, are not a promise.

Treat the status as changed only when an official Wan channel publishes the actual artifacts. Look for a Wan 3.0 repository under the Wan-Video GitHub organization, model checkpoints under the official Wan-AI accounts, and a specific license. Until those appear, the accurate description is “hosted and closed,” not “open source coming soon.”

How to verify Wan 3.0 open-source status yourself

Model availability can change quickly. Use this short verification process instead of relying on a search-result headline:

1. Check the official Wan GitHub organization for a Wan 3.0 repository.
2. Check official Wan-AI pages on Hugging Face and ModelScope for downloadable Wan 3.0 checkpoints.
3. Confirm that the repository or model card includes a license.
4. Look for inference code that actually loads the published weights.
5. Compare the release date with any article claiming the model is open.

All five checks matter. A community wrapper, an API client, or a workflow named after Wan 3.0 may be useful, but it is not the same as an official release of the underlying model.

Frequently asked questions

Is Wan 3.0 open source?

No. As of August 18, 2026, Wan 3.0 is available as an invite-only hosted model, but official model weights, inference code, and an open-source license have not been published.

Can I download Wan 3.0 model weights?

There are no official public Wan 3.0 weights to download at this time. Verify future claims through the Wan-Video GitHub organization and official Wan-AI model accounts.

Is Wan 2.2 open source?

Yes. The official Wan 2.2 repository includes inference code, links to model weights, local setup instructions, and an Apache 2.0 license.

Can I use Wan 3.0 without running it locally?

Yes. You can use a hosted implementation through the Wan 3.0 generator, subject to its current availability, account requirements, and platform terms.

Should developers use Wan 2.2 instead of Wan 3.0?

Use Wan 2.2 when local inference, source access, or customization is required. Use Wan 3.0 when you want the newer hosted workflow and do not need access to the underlying weights or code.

Conclusion

The current Wan 3.0 open source status is unambiguous: Wan 3.0 is available as a hosted model, but it is not open source as of August 18, 2026. Wan 2.2 is the open release, with public code, downloadable weights, local inference instructions, and an Apache 2.0 license. Try Wan 3.0 for the latest hosted workflow, or choose Wan 2.2 when open access and local control are essential.
