HunyuanVideo is an open-source video generation model that stands out for its superior performance compared to other closed-source models. With advanced technologies such as image-video co-training and the use of innovative Transformer architecture, it has achieved excellent results in visual quality, text-video alignment, and motion diversity. With over 13 billion parameters, HunyuanVideo is a milestone in the evolution of video generation models.

Key Points:

• HunyuanVideo surpasses closed source models such as Runway Gen-3, Luma 1.6 and Chinese video models.
• It uses an innovative "Dual-stream to Single-stream" structure for video and text processing.
• Trained with over 13 billion parameters, it is one of the largest open source models.
• Professional evaluation ranks it at the top in motion quality, alignment and content visibility.

HunyuanVideo is an innovative model in the field of video generation that combines high performance with advanced technology design, effectively competing with the best performing closed source models. The model was built using an integrated data curation and co-training approach for images and videos, effectively combining computer vision and natural language processing. With an infrastructure designed for efficiency and a Transformer-based architecture, HunyuanVideo has achieved outstanding results. During the training process, the model leveraged an innovative latent space, which was compressed by an advanced version of causal 3D VAE, thus improving the efficiency of generating high-quality videos at the original resolution and frame rate. Unlike other models, HunyuanVideo integrates a pre-trained multimodal language that enables superior understanding of text inputs, leading to more accurate alignment with video content.

One of the keys to its success is the "Dual-stream to Single-stream" architecture design. In the initial stage, the video and text token streams are processed separately to better capture the specificities of each modality. Then, in the final stage, the two streams are merged into a single representation, enabling a deep fusion of visual and semantic information, which improves overall performance. This approach, combined with a refined attention mechanism, allows the model to successfully tackle complex video generation tasks, with a more sophisticated information management than competing models that rely on structures such as CLIP and T5-XXL.

To further optimize performance, HunyuanVideo uses a 3D VAE that compresses the data into a compact latent space, thus reducing the number of tokens needed for the Transformer model. This allows to keep the resolution and fluidity of the original video intact, while reducing computational complexity. Furthermore, the prompt rewriting system, thanks to the use of Hunyuan-Large, ensures that the model correctly understands and interprets even the most complex and variable user inputs. Rewriting modes such as "Normal" and "Master" provide improved alignment and higher visual quality respectively, optimizing video generation.

For performance evaluation, 1,533 text prompts were used in a series of benchmark tests against leading closed source models. The final result showed the superiority of HunyuanVideo, especially in motion quality and alignment between text and video. The tests were conducted rigorously, avoiding manipulation of the results, to ensure an unbiased and accurate comparison. The released version of HunyuanVideo, while being of high quality, has further potential when used in its full resolution version, which offers even more detailed and precise videos.

Finally, HunyuanVideo is an important resource for the open source community, as the release of the model code and weights allows anyone to explore new ideas and develop custom applications. This will pave the way for a more dynamic ecosystem for video generation, fostering innovation and accessibility for a wide range of users.

With powerful architecture and cutting-edge performance, HunyuanVideo marks an important step in the open source video generation landscape.
