On January 3, 2026, on the social media platform "X", Tencent's official account "Hunyuan" released a blockbuster news - Tencent HY-Motion 1.0 model is officially launched! This is not an ordinary model. Just how powerful is it? Can it easily turn text into ultra-realistic 3D animations? Compared to previous models, what unique experiences can it bring?
HY-Motion 1.0 Model: Unveiling Technical Highlights
Tencent HY-Motion 1.0, based on the Diffusion Transformer (DiT) architecture and flow matching technology, boasts one billion parameters. It has successfully upgraded the flow matching DiT to over one billion parameters, setting a new upper limit for instruction following ability and generated motion quality. It's like giving a car a more powerful engine, significantly enhancing both power and performance.
It is also the industry's first action generation model with a complete pre-training → SFT → RL loop. Through this full-stage training strategy, it can optimize physical rationality and semantic accuracy. In the past, some models may have generated actions that did not conform to physical laws or deviated from the semantics of the instructions, but HY-Motion 1.0 can effectively solve these problems.
This model is also quite comprehensive in terms of category coverage, encompassing over 200 sports categories across 6 major categories, making it the most comprehensive in the industry. These categories are curated through meticulous data pipelines, akin to carefully selecting ingredients to craft a delicious meal, ensuring that every action category is of high quality and practical.
Netizens' heated discussion: open source brings infinite possibilities
As soon as the news of HY-Motion 1.0 being open-sourced was released, the comment section became lively.
Netizen Meer said excitedly, "Congratulations to the team, and thank you for making it open source. This is indeed very useful in the gaming industry."
Netizen Aaliya also commented, "This is an impressive work. Open-sourcing such a model will unlock many creative application scenarios." Everyone is eagerly anticipating the open-sourcing of this model, and believes it will shine brilliantly in various fields.
It's worth mentioning that this model is a blessing for 3D animation creators. In the past, creating 3D animations required professional skills and a significant amount of time. However, with HY-Motion 1.0, both developers and individual creators can easily get started.
It can convert natural language into high-fidelity, smooth, and diverse 3D character animations, and the generated materials can be seamlessly integrated into typical 3D animation production workflows. Imagine that creating 3D animations in the future will be as easy as writing a simple text description. Isn't that cool?
The official launch of Tencent's HY-Motion 1.0 model has undoubtedly injected new vitality into the field of 3D animation creation. Its open-source nature has provided more opportunities for people to participate in 3D animation creation. I believe that in the future, we will see the birth of more exciting 3D animation works. Let's look forward to more surprises brought by this model!
