## Project Updates
- 🔥🔥 **News**: ```2024/11/15```: We released the `CogVideoX1.5` model in the diffusers version. Only minor parameter adjustments are needed to continue using previous code.
- 🔥 News: ```2024/11/08```: We have released the CogVideoX1.5 model. CogVideoX1.5 is an upgraded version of the open-source model CogVideoX.
The CogVideoX1.5-5B series supports 10-second videos with higher resolution, and CogVideoX1.5-5B-I2V supports video generation at any resolution.
The SAT code has already been updated, while the diffusers version is still under adaptation. Download the SAT version code [here](https://huggingface.co/THUDM/CogVideoX1.5-5B-SAT).
- 🔥 **News**: ```2024/10/13```: A more cost-effective fine-tuning framework for `CogVideoX-5B` that works with a single
4090 GPU, [cogvideox-factory](https://github.com/a-r-r-o-w/cogvideox-factory), has been released. It supports
fine-tuning with multiple resolutions. Feel free to use it!
- 🔥 **News**: ```2024/10/10```: We have updated our technical report. Please
click [here](https://arxiv.org/pdf/2408.06072) to view it. More training details and a demo have been added. To see
the demo, click [here](https://yzy-thu.github.io/CogVideoX-demo/).- 🔥 **News**: ```2024/10/09```: We have publicly
released the [technical documentation](https://zhipu-ai.feishu.cn/wiki/DHCjw1TrJiTyeukfc9RceoSRnCh) for CogVideoX
fine-tuning on Feishu, further increasing distribution flexibility. All examples in the public documentation can be
fully reproduced.
- 🔥 **News**: ```2024/9/19```: We have open-sourced the CogVideoX series image-to-video model **CogVideoX-5B-I2V**.
This model can take an image as a background input and generate a video combined with prompt words, offering greater
controllability. With this, the CogVideoX series models now support three tasks: text-to-video generation, video
continuation, and image-to-video generation. Welcome to try it online
at [Experience](https://huggingface.co/spaces/THUDM/CogVideoX-5B-Space).
- 🔥 ```2024/9/19```: The Caption
model [CogVLM2-Caption](https://huggingface.co/THUDM/cogvlm2-llama3-caption), used in the training process of
CogVideoX to convert video data into text descriptions, has been open-sourced. Welcome to download and use it.
- 🔥 ```2024/8/27```: We have open-sourced a larger model in the CogVideoX series, **CogVideoX-5B**. We have
significantly optimized the model's inference performance, greatly lowering the inference threshold.
You can run **CogVideoX-2B** on older GPUs like `GTX 1080TI`, and **CogVideoX-5B** on desktop GPUs like `RTX 3060`. Please strictly
follow the [requirements](requirements.txt) to update and install dependencies, and refer
to [cli_demo](inference/cli_demo.py) for inference code. Additionally, the open-source license for
the **CogVideoX-2B** model has been changed to the **Apache 2.0 License**.

**.
- 🌱 **Source**: ```2022/5/19```: We have open-sourced the CogVideo video generation model (now you can see it in
the `CogVideo` branch). This is the first open-source large Transformer-based text-to-video generation model. You can

## Quick Start
### Prompt Optimization
Before running the model, please refer to [this guide](inference/convert_demo.py) to see how we use large models like
GLM-4 (or other comparable products, such as GPT-4) to optimize the model. This is crucial because the model is trained
with long prompts, and a good prompt directly impacts the quality of the video generation.
### SAT
**Please make sure your Python version is between 3.10 and 3.12, inclusive of both 3.10 and 3.12.**
Follow instructions in [sat_demo](sat/README.md): Contains the inference code and fine-tuning code of SAT weights. It is
recommended to improve based on the CogVideoX model structure. Innovative researchers use this code to better perform
rapid stacking and development.
### Diffusers
**Please make sure your Python version is between 3.10 and 3.12, inclusive of both 3.10 and 3.12.**
```
pip install -r requirements.txt
```
Then follow [diffusers_demo](inference/cli_demo.py): A more detailed explanation of the inference code, mentioning the
significance of common parameters.
For more details on quantized inference, please refer
to [diffusers-torchao](https://github.com/sayakpaul/diffusers-torchao/). With Diffusers and TorchAO, quantized inference
is also possible leading to memory-efficient inference as well as speedup in some cases when compiled. A full list of
memory and time benchmarks with various settings on A100 and H100 has been published
at [diffusers-torchao](https://github.com/sayakpaul/diffusers-torchao).

**Data Explanation**
+ While testing using the diffusers library, all optimizations included in the diffusers library were enabled. This
scheme has not been tested for actual memory usage on devices outside of **NVIDIA A100 / H100** architectures.
Generally, this scheme can be adapted to all **NVIDIA Ampere architecture** and above devices. If optimizations are
disabled, memory consumption will multiply, with peak memory usage being about 3 times the value in the table.
However, speed will increase by about 3-4 times. You can selectively disable some optimizations, including:
```
pipe.enable_sequential_cpu_offload()
pipe.vae.enable_slicing()
pipe.vae.enable_tiling()
```
+ For multi-GPU inference, the `enable_sequential_cpu_offload()` optimization needs to be disabled.
+ Using INT8 models will slow down inference, which is done to accommodate lower-memory GPUs while maintaining minimal
video quality loss, though inference speed will significantly decrease.
+ The CogVideoX-2B model was trained in `FP16` precision, and all CogVideoX-5B models were trained in `BF16` precision.
We recommend using the precision in which the model was trained for inference.
+ [PytorchAO](https://github.com/pytorch/ao) and [Optimum-quanto](https://github.com/huggingface/optimum-quanto/) can be
used to quantize the text encoder, transformer, and VAE modules to reduce the memory requirements of CogVideoX. This
allows the model to run on free T4 Colabs or GPUs with smaller memory! Also, note that TorchAO quantization is fully
compatible with `torch.compile`, which can significantly improve inference speed. FP8 precision must be used on
devices with NVIDIA H100 and above, requiring source installation of `torch`, `torchao` Python packages. CUDA 12.4 is recommended.
+ The inference speed tests also used the above memory optimization scheme. Without memory optimization, inference speed
increases by about 10%. Only the `diffusers` version of the model supports quantization.
+ The model only supports English input; other languages can be translated into English for use via large model
refinement.
