Running the following code will quickly load the [ACE-Step/Ace-Step1.5](https://www.modelscope.cn/models/ACE-Step/Ace-Step1.5) model and perform inference. VRAM management is enabled, and the framework will automatically control the loading of model parameters based on available VRAM. The model can run with a minimum of 3GB VRAM.

# ACE-Step
|
||||
|
||||
ACE-Step 1.5 is an open-source music generation model based on DiT architecture, supporting text-to-music, audio cover, repainting and other functionalities, running efficiently on consumer-grade hardware.
|
||||
|
||||
## 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 [ACE-Step/Ace-Step1.5](https://www.modelscope.cn/models/ACE-Step/Ace-Step1.5) model for inference. VRAM management is enabled, the framework automatically controls parameter loading based on available VRAM, requiring a minimum of 3GB VRAM.

prompt = "An explosive, high-energy pop-rock track with a strong anime theme song feel. The song kicks off with a catchy, synthesized brass fanfare over a driving rock beat with punchy drums and a solid bassline. A powerful, clear male vocal enters with a theatrical and energetic delivery, soaring through the verses and hitting powerful high notes in the chorus. The arrangement is dense and dynamic, featuring rhythmic electric guitar chords, brief instrumental breaks with synth flourishes, and a consistent, danceable groove throughout. The overall mood is triumphant, adventurous, and exhilarating."

# ACE-Step
|
||||
|
||||
ACE-Step 1.5 是一个开源音乐生成模型，基于 DiT 架构，支持文生音乐、音频翻唱、局部重绘等多种功能，可在消费级硬件上高效运行。
|
||||
|
||||
## 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 [ACE-Step/Ace-Step1.5](https://www.modelscope.cn/models/ACE-Step/Ace-Step1.5) 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 3G 显存即可运行。

prompt = "An explosive, high-energy pop-rock track with a strong anime theme song feel. The song kicks off with a catchy, synthesized brass fanfare over a driving rock beat with punchy drums and a solid bassline. A powerful, clear male vocal enters with a theatrical and energetic delivery, soaring through the verses and hitting powerful high notes in the chorus. The arrangement is dense and dynamic, featuring rhythmic electric guitar chords, brief instrumental breaks with synth flourishes, and a consistent, danceable groove throughout. The overall mood is triumphant, adventurous, and exhilarating."

The arrangement is dense and dynamic, featuring rhythmic electric guitar chords, brief instrumental breaks with synth flourishes, and a consistent, danceable groove throughout.

The song kicks off with a catchy, synthesized brass fanfare over a driving rock beat with punchy drums and a solid bassline. A powerful, clear male vocal enters with a theatrical and energetic delivery, soaring through the verses and hitting powerful high notes in the chorus.

The song kicks off with a catchy, synthesized brass fanfare over a driving rock beat with punchy drums and a solid bassline. A powerful, clear male vocal enters with a theatrical and energetic delivery, soaring through the verses and hitting powerful high notes in the chorus. The arrangement is dense and dynamic, featuring rhythmic electric guitar chords, brief instrumental breaks with synth flourishes, and a consistent, danceable groove throughout. The overall mood is triumphant, adventurous, and exhilarating."

A powerful, clear male vocal enters with a theatrical and energetic delivery, soaring through the verses and hitting powerful high notes in the chorus. The arrangement is dense and dynamic, featuring rhythmic electric guitar chords, brief instrumental breaks with synth flourishes, and a consistent, danceable groove throughout. The overall mood is triumphant, adventurous, and exhilarating."
