CogVideoX is an open-source video generation model originating from [Qingying](https://chatglm.cn/video?fr=osm_cogvideo). CogVideoX1.1 is the upgraded version of the open-source CogVideoX model.

The CogVideoX1.1-5B series model supports **10-second** videos and higher resolutions. The `CogVideoX1.1-5B-I2V` variant supports **any resolution** for video generation.

This repository contains the SAT-weight version of the CogVideoX1.1-5B 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
