-## **Abstract**
-We present HunyuanVideo, a novel open-source video foundation model that exhibits performance in video generation that is comparable to, if not superior to, leading closed-source models. In order to train HunyuanVideo model, we adopt several key technologies for model learning, including data curation, image-video joint model training, and an efficient infrastructure designed to facilitate large-scale model training and inference. Additionally, through an effective strategy for scaling model architecture and dataset, we successfully trained a video generative model with over 13 billion parameters, making it the largest among all open-source models. 
-
-We conducted extensive experiments and implemented a series of targeted designs to ensure high visual quality, motion diversity, text-video alignment, and generation stability. According to professional human evaluation results, HunyuanVideo outperforms previous state-of-the-art models, including Runway Gen-3, Luma 1.6, and 3 top-performing Chinese video generative models. By releasing the code and weights of the foundation model and its applications, we aim to bridge the gap between closed-source and open-source video foundation models. This initiative will empower everyone in the community to experiment with their ideas, fostering a more dynamic and vibrant video generation ecosystem.

-
-## **HunyuanVideo Overall Architecture**
-
-HunyuanVideo is trained on a spatial-temporally
-compressed latent space, which is compressed through a Causal 3D VAE. Text prompts are encoded
-using a large language model, and used as the conditions. Taking Gaussian noise and the conditions as
-input, our generative model produces a output latent, which is then decoded to images or videos through
-the 3D VAE decoder.

-
-## 🎉 **HunyuanVideo Key Features**
-
-### **Unified Image and Video Generative Architecture**
-HunyuanVideo introduces the Transformer design and employs a Full Attention mechanism for unified image and video generation. 
-Specifically, we use a "Dual-stream to Single-stream" hybrid model design for video generation. In the dual-stream phase, video and text
-tokens are processed independently through multiple Transformer blocks, enabling each modality to learn its own appropriate modulation mechanisms without interference. In the single-stream phase, we concatenate the video and text
-tokens and feed them into subsequent Transformer blocks for effective multimodal information fusion.
-This design captures complex interactions between visual and semantic information, enhancing
-overall model performance.

-</p>
-
-### **MLLM Text Encoder**
-Some previous text-to-video models typically use pre-trained CLIP and T5-XXL as text encoders where CLIP uses Transformer Encoder and T5 uses an Encoder-Decoder structure. In contrast, we utilize a pre-trained Multimodal Large Language Model (MLLM) with a Decoder-Only structure as our text encoder, which has the following advantages: (i) Compared with T5, MLLM after visual instruction finetuning has better image-text alignment in the feature space, which alleviates the difficulty of the instruction following in diffusion models; (ii)
-Compared with CLIP, MLLM has demonstrated superior ability in image detail description
-and complex reasoning; (iii) MLLM can play as a zero-shot learner by following system instructions prepended to user prompts, helping text features pay more attention to key information. In addition, MLLM is based on causal attention while T5-XXL utilizes bidirectional attention that produces better text guidance for diffusion models. Therefore, we introduce an extra bidirectional token refiner to enhance text features.

-
-### **3D VAE**
-HunyuanVideo trains a 3D VAE with CausalConv3D (Partially referred to [Open-Sora-Plan](https://github.com/PKU-YuanGroup/Open-Sora-Plan) ) to compress pixel-space videos and images into a compact latent space. We set the compression ratios of video length, space, and channel to 4, 8, and 16 respectively. This can significantly reduce the number of tokens for the subsequent diffusion transformer model, allowing us to train videos at the original resolution and frame rate.
-<p align="center">

-</p>
-
-### **Prompt Rewrite**
-To address the variability in linguistic style and length of user-provided prompts, we fine-tune the [Hunyuan-Large model](https://github.com/Tencent/Tencent-Hunyuan-Large) as our prompt rewrite model to adapt the original user prompt to model-preferred prompt.
-
-We provide two rewrite modes: Normal mode and Master mode, which can be called using different prompts. The prompts are shown [here](hyvideo/prompt_rewrite.py). The Normal mode is designed to enhance the video generation model's comprehension of user intent, facilitating a more accurate interpretation of the instructions provided. The Master mode enhances the description of aspects such as composition, lighting, and camera movement, which leans towards generating videos with a higher visual quality. However, this emphasis may occasionally result in the loss of some semantic details. 
-
-The Prompt Rewrite Model can be directly deployed and inferred using the [Hunyuan-Large original code](https://github.com/Tencent/Tencent-Hunyuan-Large). We release the weights of the Prompt Rewrite Model [here](https://huggingface.co/Tencent/HunyuanVideo-PromptRewrite).

-
-
-## 📈 Comparisons
-
-To evaluate the performance of HunyuanVideo, we selected five strong baselines from closed-source video generation models. In total, we utilized 1,533 text prompts, generating an equal number of video samples with HunyuanVideo in a single run. For a fair comparison, we conducted inference only once, avoiding any cherry-picking of results. When comparing with the baseline methods, we maintained the default settings for all selected models, ensuring consistent video resolution. Videos were assessed based on three criteria: Text Alignment, Motion Quality, and Visual Quality. More than 60 professional evaluators performed the evaluation. Notably, HunyuanVideo demonstrated the best overall performance, particularly excelling in motion quality. Please note that the evaluation is based on Hunyuan Video's high-quality version. This is different from the currently released fast version.

-## 🚀 Parallel Inference on Multiple GPUs by xDiT
-
-[xDiT](https://github.com/xdit-project/xDiT) is a Scalable Inference Engine for Diffusion Transformers (DiTs) on multi-GPU Clusters.
-It has successfully provided low-latency parallel inference solutions for a variety of DiTs models, including mochi-1, CogVideoX, Flux.1, SD3, etc. This repo adopted the [Unified Sequence Parallelism (USP)](https://arxiv.org/abs/2405.07719) APIs for parallel inference of the HunyuanVideo model.
-
-### Using Command Line
-
-For example, to generate a video with 8 GPUs, you can use the following command:
-
-```bash
-cd HunyuanVideo
-
-torchrun --nproc_per_node=8 sample_video.py \
-    --video-size 1280 720 \
-    --video-length 129 \
-    --infer-steps 50 \
-    --prompt "A cat walks on the grass, realistic style." \
-    --flow-reverse \
-    --seed 42 \
-    --ulysses-degree 8 \
-    --ring-degree 1 \
-    --save-path ./results
-```
-
-You can change the `--ulysses-degree` and `--ring-degree` to control the parallel configurations for the best performance. The valid parallel configurations are shown in the following table.

-## 🚀  FP8 Inference
-
-Using HunyuanVideo with FP8 quantized weights, which saves about 10GB of GPU memory. You can download the [weights](https://huggingface.co/tencent/HunyuanVideo/blob/main/hunyuan-video-t2v-720p/transformers/mp_rank_00_model_states_fp8.pt) and [weight scales](https://huggingface.co/tencent/HunyuanVideo/blob/main/hunyuan-video-t2v-720p/transformers/mp_rank_00_model_states_fp8_map.pt) from Huggingface.
-
-### Using Command Line
-
-Here, you must explicitly specify the FP8 weight path. For example, to generate a video with fp8 weights, you can use the following command:
-
-```bash
-cd HunyuanVideo
-
-DIT_CKPT_PATH={PATH_TO_FP8_WEIGHTS}/{WEIGHT_NAME}_fp8.pt
-
-python3 sample_video.py \
-    --dit-weight ${DIT_CKPT_PATH} \
-    --video-size 1280 720 \
-    --video-length 129 \
-    --infer-steps 50 \
-    --prompt "A cat walks on the grass, realistic style." \
-    --seed 42 \
-    --embedded-cfg-scale 6.0 \
-    --flow-shift 7.0 \
-    --flow-reverse \
-    --use-cpu-offload \
-    --use-fp8 \
-    --save-path ./results
-```
