+
+## Installation Instructions
+
+The installation instructions are simple. Just clone the repo and install the requirements.
+
+```shell
+git clone https://github.com/IamCreateAI/Ruyi-Models
+cd Ruyi-Models
+pip install -r requirements.txt
+```
+
+### For ComfyUI Users
+
+#### Method (1): Installation via ComfyUI Manager
+
+Download and install [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager).
+
+```shell
+cd ComfyUI/custom_nodes/
+git clone https://github.com/ltdrdata/ComfyUI-Manager.git
+
+# install requirements
+pip install -r ComfyUI-Manager/requirements.txt
+```
+
+Next, start ComfyUI and open the Manager. Select Custom Nodes Manager, then search for "Ruyi". You should see ComfyUI-Ruyi as shown in the screenshot below. Click "Install" to proceed.
+
+<div align=center>
+  <img src="https://github.com/user-attachments/assets/10dda65f-13d5-4da8-9437-9c98b114536c"></img>
+</div>
+
+Finally, search for "ComfyUI-VideoHelperSuite" and install it as well.
+
+#### Method (2): Manual Installation
+
+Download and save this repository to the path *ComfyUI/custom_nodes/Ruyi-Models*.
+
+```shell
+# download the repo
+cd ComfyUI/custom_nodes/
+git clone https://github.com/IamCreateAI/Ruyi-Models.git
+
+# install requirements
+pip install -r Ruyi-Models/requirements.txt
+```
+
+Install the dependency [ComfyUI-VideoHelperSuite](https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite) to display video output (skip this step if already installed).
+
+```shell
+# download ComfyUI-VideoHelperSuite
+cd ComfyUI/custom_nodes/
+git clone https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite.git
+
+# install requirements
+pip install -r ComfyUI-VideoHelperSuite/requirements.txt
+```
+
+##### For Windows Users
+
+When using the Windows operating system, a common distribution is [ComfyUI_windows_portable_nvidia](https://github.com/comfyanonymous/ComfyUI/releases). When launched with `run_nvidia_gpu.bat`, it utilizes the embedded Python interpreter included with the package. Therefore, the environment needs to be set up within this built-in Python.
+
+For example, if the extracted directory of the distribution is ComfyUI_windows_portable, you can typically use the following command to download the repository and install the runtime environment:
+
+```shell
+# download the repo
+cd ComfyUI_windows_portable\ComfyUI\custom_nodes
+git clone https://github.com/IamCreateAI/Ruyi-Models.git
+
+# install requirements using embedded Python interpreter
+..\..\python_embeded\python.exe -m pip install -r Ruyi-Models\requirements.txt
+```
+
+## Download Model (Optional)
+
+Download the model and save it to certain path. To directly run our model, it is recommand to save the models into _Ruyi-Models/models_ folder. For ComfyUI users, the path should be _ComfyUI/models/Ruyi_.
+
+| Model Name | Type | Resolution | Max Frames | Frames per Second | Storage Space | Download |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Ruyi-Mini-7B | Image to Video | 512 & 768 | 120 | 24 | 17 GB | [🤗](https://huggingface.co/IamCreateAI/Ruyi-Mini-7B) |
+
+For example, after downloading Ruyi-Mini-7B, the file path structure should be:
+
+```
+📦 Ruyi-Models/models/ or ComfyUI/models/Ruyi/
+├── 📂 Ruyi-Mini-7B/
+│   ├── 📂 transformers/
+│   ├── 📂 vae/
+│   └── 📂 ...
+```
+
+> This repository **supports automatic model downloading**, but manual downloading provides more control. For instance, you can download the model to another location and then link it to the *ComfyUI/models/Ruyi* path using symbolic links or similar methods.
+
+## How to Use
+
+We provide two ways to run our model. The first is directly using python code.
+
+```
+python3 predict_i2v.py
+```
+
+Specifically, the script downloads the model to the _Ruyi-Models/models_ folder and uses images from the [_assets_](./assets/) folder as the start and end frames for video inference. You can modify the variables in the script to replace the input images and set parameters such as video length and resolution.
+
+For users with more than 24GB of GPU memory, you can use predict_i2v_80g.py to enhance generation speed. For those with less GPU memory, we offer parameters to optimize memory usage, enabling the generation of higher resolution and longer videos by extending the inference time. The effects of these parameters can be found in the [GPU memory optimization section](#gpu-memory-optimization) section below.
+
+Or use ComfyUI wrapper in our github repo, the detail of ComfyUI nodes is described in [_comfyui/README.md_](./comfyui/README.md).

+We provide the options **`GPU_memory_mode` and `GPU_offload_steps` to reduce GPU memory usage**, catering to different user needs.
+
+Generally speaking, using **less GPU memory requires more RAM and results in longer generation times**. Below is a reference table of expected GPU memory usage and generation times. Note that, the GPU memory reported below is the `max_memory_allocated()` value. The values read from nvidia-smi may be higher than the reported values because CUDA occupies some GPU memory (usually between 500 - 800 MiB), and PyTorch's caching mechanism also requests additional GPU memory.
+
+Additionally, the community and we have created a detailed table featuring various resolutions and option combinations, which can be found in the [gpu_memory_appendix.md](assets/gpu_memory_appendix.md). We encourage community members to help us complete the table.

+  <img src="https://github.com/user-attachments/assets/10dda65f-13d5-4da8-9437-9c98b114536c"></img>
+</div>
+
+最后，搜索 “ComfyUI-VideoHelperSuite” 并安装。
+
+#### 方法（2）：手动安装
+
+- 下载并保存本仓库到 *ComfyUI/custom_nodes/Ruyi-Models* 路径。
+
+```shell
+# download the repo
+cd ComfyUI/custom_nodes/
+git clone https://github.com/IamCreateAI/Ruyi-Models.git
+
+# install requirements
+pip install -r Ruyi-Models/requirements.txt
+```
+
+- 安装依赖项 [ComfyUI-VideoHelperSuite](https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite) 以显示视频输出（如已安装，请跳过本步骤）。
+
+```shell
+# download ComfyUI-VideoHelperSuite
+cd ComfyUI/custom_nodes/
+git clone https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite.git
+
+# install requirements
+pip install -r ComfyUI-VideoHelperSuite/requirements.txt
+```
+
+##### Windows 操作系统下的安装方法
+
+在使用Windows操作系统时，[ComfyUI_windows_portable_nvidia](https://github.com/comfyanonymous/ComfyUI/releases) 是一种常见的发行版。当通过 `run_nvidia_gpu.bat` 启动时，会使用其中嵌入的 Python 解释器。因此，需要在这个内置的 Python 环境中安装运行环境。
+
+例如，如果提取后的发行版目录是 _ComfyUI_windows_portable_，通常可使用以下命令下载仓库并安装运行时环境：
+
+```shell
+# download the repo
+cd ComfyUI_windows_portable\ComfyUI\custom_nodes
+git clone https://github.com/IamCreateAI/Ruyi-Models.git
+
+# install requirements using embedded Python interpreter
+..\..\python_embeded\python.exe -m pip install -r Ruyi-Models\requirements.txt
+```
+
+## 下载模型（可选）
+
+下载模型并将其保存到指定路径。为了直接运行 Ruyi 模型，建议将模型保存到 _Ruyi-Models/models_ 文件夹中。对于 ComfyUI 用户，路径应为 _ComfyUI/models/Ruyi_。
+
+| 名称 | 类型 | 分辨率 | 最大帧数 | 每秒帧数 | 存储空间 | 下载地址 |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Ruyi-Mini-7B | 图生视频 | 512 & 768 | 120 | 24 | 17 GB | [🤗](https://huggingface.co/IamCreateAI/Ruyi-Mini-7B) |
+
+例如，下载 Ruyi-Mini-7B 后，文件的路径结构应该为：
+
+```
+📦 Ruyi-Models/models/ or ComfyUI/models/Ruyi/
+├── 📂 Ruyi-Mini-7B/
+│   ├── 📂 transformers/
+│   ├── 📂 vae/
+│   └── 📂 ...
+```
+
+> 本仓库**支持自动下载模型功能**，但手动下载提供了更多的可控性。例如，可以下载模型到其他位置，再通过软链接等方式链接到 *ComfyUI/models/Ruyi* 路径。
+
+## 使用方法
+
+我们提供两种运行模型的方法。第一种是直接使用Python代码。
+
+```shell
+python3 predict_i2v.py
+```
+
+具体来说，该脚本将模型下载到 _Ruyi-Models/models_ 文件夹，并使用 _[assets](./assets)_ 文件夹中的图像作为视频推理的起始帧和结束帧。您可以修改脚本中的变量来替换输入图像，并设置视频长度和分辨率等参数。
+
+对于显存超过 24GB 的用户，可以使用 predict_i2v_80g.py 来提高生成速度。对于显存较少的用户，提供了优化显存使用的参数，这些参数可以通过延长推理时间来生成更高分辨率和更长时长的视频。这些参数的影响可以在下面的显存优化选项小节找到。
+
+或者，您可以使用我们 GitHub 仓库中的 ComfyUI 封装，ComfyUI 节点的详细信息在 _[comfyui/README_CN.md](comfyui/README_CN.md)_ 中描述。

+
+## 显存优化选项
+
+提供了 **`GPU_memory_mode` 和 `GPU_offload_steps`** 选项以**降低显存占用**，满足不同用户的需求。
+
+通常来说，**使用更少的显存，需要更多的内存和更长的生成时间**。以下列出预期显存使用和生成时间的参考表格。请注意，下面报告的显存是 `max_memory_allocated()` 的返回值，而 nvidia-smi 的显存数值通常会高于报告的数值。因为 CUDA 会占用一些显存（通常在500 - 800 MiB之间），而 PyTorch 的缓存机制也会请求额外的显存。
+
+此外，在社区的帮助下创建了一张详细的表格 [gpu_memory_appendix.md](assets/gpu_memory_appendix.md)，包含了更多分辨率和选项组合。欢迎社区成员帮助完善表格。

+
+> The GPU memory reported below is the `max_memory_allocated()` value. The values read from nvidia-smi may be higher than the reported values because CUDA occupies some GPU memory (usually between 500 - 800 MiB), and PyTorch's caching mechanism also requests additional GPU memory.

+> The GPU memory reported below is the `max_memory_allocated()` value. The values read from nvidia-smi may be higher than the reported values because CUDA occupies some GPU memory (usually between 500 - 800 MiB), and PyTorch's caching mechanism also requests additional GPU memory.

Ruyi-Models/comfyui/README.md

+## ComfyUI Nodes
+
+After installation, you can find the three nodes provided by this repository in the *Add Node - Ruyi* menu, as shown in the image below:
+
+<div align=center>
+  <img src="https://github.com/user-attachments/assets/0760399c-c57f-465d-9685-ef910b60421c"></img>
+</div>
+
+The following sections will introduce the functions and parameters of each node.
+
+> Note: The new version of ComfyUI nodes is displayed in the NODE LIBRARY on the left side of the interface.
+
+### Load Model
+
+The Load Model node is used to load the model from disk. It also provides the functionality for **automatic model downloading** (auto_download parameter).
+
+<div align=center>
+  <img src="https://github.com/user-attachments/assets/2e9fcbb5-6f7c-451c-b742-5b844e949a01"></img>
+</div>
+
+- **model**: Select which model to use. Currently, Ruyi-Mini-7B is the only option.
+- **auto_download**: Whether to automatically download. Defaults to yes. If the model is detected as missing or incomplete, it will automatically download the model to the *ComfyUI/models/Ruyi* path.
+- **auto_update**: Whether to automatically check for and update the current model. Defaults to yes. When auto_download is enabled, the system will automatically check for updates to the model and download any updates to the *ComfyUI/models/Ruyi* directory. Please note that this feature relies on the caching mechanism of huggingface_hub, so do not delete the *.cache* folder in the model directory to ensure a smooth update process.
+
+### Load LoRA
+
+The Load LoRA node is used to load LoRA models, which need to be placed in the *ComfyUI/models/loras* path.
+
+<div align=center>
+  <img src="https://github.com/user-attachments/assets/33f860ca-94c9-4686-afe4-7e00de15b0ce"></img>
+</div>
+
+- **lora_name**: The LoRA to be loaded; it will automatically search and display all model files in the *ComfyUI/models/loras* path.
+- **strength_model**: The degree of influence of the LoRA, typically set between 1.0 and 1.4 for optimal results based on experience.
+
+### Sampler for Image to Video
+
+The Sampler for Image to Video node is used to generate videos based on input images. The starting frame image (start_img) is a required input, while the ending frame image (end_img) is optional. This node also supports **camera control** (camera_direction parameter) and **motion amplitude control** of the video subject (motion parameter).
+
+<div align=center>
+  <img src="https://github.com/user-attachments/assets/e5078e95-7100-4e9b-9baa-0d534b085e7a"></img>
+</div>
+
+- **start_img**: The starting frame image.
+- **end_img**: The ending frame image, optional input.
+- **video_length**: The length of the video, which must be divisible by 8, with a maximum of 120 frames.
+- **base_resolution**: The video resolution, such as 512, indicates that the generated video will have pixel dimensions close to 512 x 512. The model will automatically select the closest output video aspect ratio based on the input image.
+- **seed**: A random number; different random numbers usually generate different videos. If the generated video does not meet requirements, this value can be adjusted to try other generation possibilities.
+- **control_after_generate**: The method of changing the random number after each generation.
+  - **Fixed** indicates the seed is fixed.
+  - **Increment** indicates the seed is increased by one each time.
+  - **Decrement** indicates the seed is decreased by one each time.
+  - **Randomize** indicates the seed is randomly set each time.
+- **steps**: The number of iterations for video generation. **More iterations require more time**. Typically, 25 iterations yield good results.
+- **cfg**: The guidance of instructions (such as input images). A higher value indicates better guidance, with values between 7 and 10 usually achieving better generation results.
+- **motion**: Controls the motion amplitude of the video subject.
+  - **1** indicates minimal motion, which means the video subject is nearly static.
+  - **2** indicates normal motion, which could be used in most case.
+  - **3** indicates significant motion. The video subject is trying to move as much as possible.
+  - **4** indicates a very large motion. Sometimes the video subject may move out of the camera frame.
+  - **Auto** indicates the motion is automatically determined by the model.
+- **camera_direction**: Camera movement.
+  - **Static** indicates a stationary camera.
+  - **Left** indicates the camera moves left.

+  - **Up** indicates the camera moves up.
+  - **Down** indicates the camera moves down.
+  - **Auto** indicates automatic determination.
+- **GPU_memory_mode**: Determines how GPU memory is utilized.
+  - **normal_mode** is the default mode, using more GPU memory and generating faster.
+  - **low_memory_mode** is the low memory mode, which significantly reduces GPU memory usage but severely impacts generation speed.
+- **GPU_offload_steps**: Used to **optimize GPU memory usage** by moving some temporary variables from GPU memory to RAM, which **increases memory usage and decreases generation speed**.
+  - **0** indicates no optimization.
+  - **1 - 10**, where 1 has the least GPU memory usage and the slowest generation speed; 10 has the most GPU memory usage (less than the non-optimized case) and the fastest generation speed.
+  - Generally, with 24GB of GPU memory, you can use 7 to generate a 512 resolution, 120 frame video. For more detailed data, please refer to the following.
+
+## Workflow Example
+
+This section presents an example workflow for generating videos from images. You can import the workflow using the *Load* button in the (bottom right) menu. Note that the new version of ComfyUI move the menu to the top left, and allows you to load workflows through the *Workflow - Open* option.
+
+The workflows are located in the *[comfyui/workflows/](workflows/)* directory, while the assets can be found in the *[assets/](../assets/)* directory.
+
+After importing the workflow, you **need to manually re-specify the input image for the LoadImage input node**. Since the workflow file can only record the names of input files, it does require manual configuration.
+
+### Image to Video (Starting Frame)
+
+The workflow corresponds to the *[workflow-ruyi-i2v-start-frame.json](workflows/workflow-ruyi-i2v-start-frame.json)* file. For users with larger GPU memory, you can also use *[workflow-ruyi-i2v-start-frame-80g.json](workflows/workflow-ruyi-i2v-start-frame-80g.json)* to enhance the generation speed.

+</div>
+
+### Image to Video (Starting and Ending Frames)
+
+The workflow corresponds to the *[workflow-ruyi-i2v-start-end-frames.json](workflows/workflow-ruyi-i2v-start-end-frames.json)* file. For users with larger GPU memory, you can also use *[workflow-ruyi-i2v-start-end-frames-80g.json](workflows/workflow-ruyi-i2v-start-end-frames-80g.json)* to enhance the generation speed.

+
+## Frequently Asked Questions
+
+### Model loading error: LoadModel: ConnectionError (MaxRetryError)
+
+This is usually caused by network issues leading to a failure in downloading from huggingface_hub. If the network is functioning properly, simply rerunning the LoadModel node should resolve the issue.
+
+### Video generation speed is slow and far below expectations
+
+- First, check if the low_memory_mode in the Load Model node is enabled. This mode significantly reduces video generation speed.
+- Second, verify the version of PyTorch. PyTorch version 2.2 supports FlashAttention-2 ([link](https://pytorch.org/blog/pytorch2-2/)), which can greatly enhance computational efficiency. Installing the latest version of PyTorch can effectively improve generation speed.

+
+## 工作流样例
+
+本节展示了图生视频的工作流样例，可通过菜单中的 *Load* 按钮导入工作流。新版 ComfyUI 可通过左上方菜单的 *Workflow - Open* 加载工作流。
+
+工作流位于 *[comfyui/workflows/](workflows/)* 目录中，素材位于 *[assets/](../assets/)* 目录中。
+
+导入工作流后，**需要手动重新指定输入节点 LoadImage 的输入图片**，由于工作流文件只能记录输入文件的名字，所以目前只能手动设置。
+
+### 图生视频（首帧）
+
+工作流对应 *[workflow-ruyi-i2v-start-frame.json](workflows/workflow-ruyi-i2v-start-frame.json)* 文件。对于显存较大的用户，也可以使用 *[workflow-ruyi-i2v-start-frame-80g.json](workflows/workflow-ruyi-i2v-start-frame-80g.json)* 以提高生成速度。
+
+<div align=center>
+  <img style="width:80%" src="https://github.com/user-attachments/assets/4c0a58b8-ea04-4656-bf1f-b8665a3802a3"></img>
+</div>
+
+### 图生视频（首尾帧）
+
+工作流对应 *[workflow-ruyi-i2v-start-end-frames.json](workflows/workflow-ruyi-i2v-start-end-frames.json)* 文件。对于显存较大的用户，也可以使用 *[workflow-ruyi-i2v-start-end-frames-80g.json](workflows/workflow-ruyi-i2v-start-end-frames-80g.json)* 以提高生成速度。

+</div>
+
+## 常见问题
+
+### 模型加载错误，LoadModel: ConnectionError (MaxRetryError)
+
+通常是网络问题导致 huggingface_hub 下载失败。网络正常的情况下，再次运行 LoadModel 节点即可解决。
+
+### 视频生成速度慢、远低于预期
+
+- 首先，请检查是否开启 Load Model 节点中 GPU_memory_mode 的 low_memory_mode，此模式会大幅降低视频生成速度。
+- 其次，请检查 PyTorch 版本。PyTorch 在 2.2 版本支持了 FlashAttention-2（[链接](https://pytorch.org/blog/pytorch2-2/)），能大幅提升计算效率。安装新版本的 PyTorch 能够有效提升生成速度。
