CogVideoX is an open-source video generation model originating from [Qingying](https://chatglm.cn/video?fr=osm_cogvideo). CogVideoX1.5 is the upgraded version of the open-source CogVideoX model. The CogVideoX1.5-5B series model supports **10-second** videos and higher resolutions. The `CogVideoX1.5-5B-I2V` variant supports **any resolution** for video generation. This repository contains the SAT-weight version of the CogVideoX1.5-5B model, specifically including the following modules: ## Transformer Includes weights for both I2V and T2V models. Specifically, it includes the following modules: ``` ├── transformer_i2v │ ├── 1000 │ │ └── mp_rank_00_model_states.pt │ └── latest └── transformer_t2v ├── 1000 │ └── mp_rank_00_model_states.pt └── latest ``` Please select the corresponding weights when performing inference. ## VAE The VAE part is consistent with the CogVideoX-5B series and does not require updating. You can also download it directly from here. Specifically, it includes the following modules: ``` └── vae └── 3d-vae.pt ``` ## Text Encoder Consistent with the diffusers version of CogVideoX-5B, no updates are necessary. You can also download it directly from here. Specifically, it includes the following modules: ``` ├── t5-v1_1-xxl ├── added_tokens.json ├── config.json ├── model-00001-of-00002.safetensors ├── model-00002-of-00002.safetensors ├── model.safetensors.index.json ├── special_tokens_map.json ├── spiece.model └── tokenizer_config.json 0 directories, 8 files ``` ## Model License This model is released under the [CogVideoX LICENSE](LICENSE). ## Citation ``` @article{yang2024cogvideox, title={CogVideoX: Text-to-Video Diffusion Models with An Expert Transformer}, author={Yang, Zhuoyi and Teng, Jiayan and Zheng, Wendi and Ding, Ming and Huang, Shiyu and Xu, Jiazheng and Yang, Yuanming and Hong, Wenyi and Zhang, Xiaohan and Feng, Guanyu and others}, journal={arXiv preprint arXiv:2408.06072}, year={2024} } ```
