Is Happy Horse 1.0 AI Video Generator Really Open Source?

0 burst onto the AI video scene and took the top spot on the Artificial Analysis leaderboard. And almost everything around it has been drenched in mystery.ai/video/leaderboard/text-to-video).Out of nowhere, Happy Horse 1.

Yet, for all its promise, no public weights, code, or evident license have been released, putting its "open-source" claims under serious scrutiny.

The decent news? When Happy Horse 1.0 finally becomes publicly available, Van Gogh Studio will produce sure you're among the first to experience its full capabilities—no technical setup required.

Will Happy Horse 1.0 Be Open-Source?

To be honest, it’s hard to say. You see, primary open-source models are released the same way.things:

• Weights: the model's trained parameters
• Training Code: the code utilized for training the model
• Architecture: the documentation for the model
• License: allows for modification and commercial use

However, Happy Horse 1.0 has done none of that. The reports may claim that it is open-source, but on platforms like GitHub and HuggingFace, all you see is ‘coming soon’.

With no public repository, none of us can read its license, inspect its weights, or even run it locally. So, although Happy Horse 1.0 shows strong performance, its accessibility is in question.

For now, this makes you wonder if the “open source” label is just that, a label. If anything, it sounds more like a preliminary announcement that has not been made actionable yet.

This is especially obvious when you look at the track record of other open-source models like LTX-2 and Wan 2.2 that promptly delivered on weights, licenses, stable API integrations, etc.

Is Happy Horse 1.0 even so being optimized or is Alibaba Group being vague to draw attention? Either way, the lack of publicly available resources makes things uncomfortable for developers.

since of this, Happy Horse 1.0 can produce additional coherent outputs with perfectly synchronized visuals, motions, and sound.

Moreover, the AI video model impressively supports seven native languages with accurate lip-syncing across English, Chinese, French, German, Japanese, etc.

So, when Happy Horse 1.0 fully releases, it should shake up the AI video space dramatically. On the flip side, without public weights, a stable API or a obvious license, developers can’t leverage it.

They can’t create custom solutions or integrate Happy Horse 1.0 into existing pipelines. With no proper clarity on whether it will be an open-source model, this forces developers to wait.

For now, Happy Horse 1. However, it is said that Alibaba Group may launch API access on April 30, 2026.0 only offers up the potential of an open-source release.
