# JoyAI-Image
|
||||||
|
|
||||||
|
JoyAI-Image is a unified multi-modal foundation model open-sourced by JD.com, supporting image understanding, text-to-image generation, and instruction-guided image editing.
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
Before performing model inference and training, please install DiffSynth-Studio first.
|
||||||
|
|
||||||
|
```shell
|
||||||
|
git clone https://github.com/modelscope/DiffSynth-Studio.git
|
||||||
|
cd DiffSynth-Studio
|
||||||
|
pip install -e .
|
||||||
|
```
|
||||||
|
|
||||||
|
For more information on installation, please refer to [Setup Dependencies](../Pipeline_Usage/Setup.md).
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
Running the following code will load the [jd-opensource/JoyAI-Image-Edit](https://modelscope.cn/models/jd-opensource/JoyAI-Image-Edit) model for inference. VRAM management is enabled, the framework automatically controls parameter loading based on available VRAM, requiring a minimum of 4GB VRAM.

## Model Inference
|
||||||
|
|
||||||
|
The model is loaded via `JoyAIImagePipeline.from_pretrained`, see [Loading Models](../Pipeline_Usage/Model_Inference.md#loading-models) for details.
|
||||||
|
|
||||||
|
The input parameters for `JoyAIImagePipeline` inference include:
|
||||||
|
|
||||||
|
* `prompt`: Text prompt describing the desired image editing effect.
|
||||||
|
* `negative_prompt`: Negative prompt specifying what should not appear in the result, defaults to empty string.
|
||||||
|
* `cfg_scale`: Classifier-free guidance scale factor, defaults to 5.0. Higher values make the output more closely follow the prompt.
|
||||||

# JoyAI-Image
|
||||||
|
|
||||||
|
JoyAI-Image 是京东开源的统一多模态基础模型，支持图像理解、文生图生成和指令引导的图像编辑。
|
||||||
|
|
||||||
|
## 安装
|
||||||
|
|
||||||
|
在使用本项目进行模型推理和训练前，请先安装 DiffSynth-Studio。
|
||||||
|
|
||||||
|
```shell
|
||||||
|
git clone https://github.com/modelscope/DiffSynth-Studio.git
|
||||||
|
cd DiffSynth-Studio
|
||||||
|
pip install -e .
|
||||||
|
```
|
||||||
|
|
||||||
|
更多关于安装的信息，请参考[安装依赖](../Pipeline_Usage/Setup.md)。
|
||||||
|
|
||||||
|
## 快速开始
|
||||||
|
|
||||||
|
运行以下代码可以快速加载 [jd-opensource/JoyAI-Image-Edit](https://modelscope.cn/models/jd-opensource/JoyAI-Image-Edit) 模型并进行推理。显存管理已启动，框架会自动根据剩余显存控制模型参数的加载，最低 4G 显存即可运行。
