 > Currently, the development personnel of this project are limited, with most of the work handled by [Artiprocher](https://github.com/Artiprocher) and [mi804](https://github.com/mi804). Therefore, the progress of new feature development will be relatively slow, and the speed of responding to and resolving issues is limited. We apologize for this and ask developers to understand.
 
+- **April 27, 2026** We support ACE-Step-1.5! Support includes text-to-music generation, low VRAM inference, and LoRA training capabilities. For details, please refer to the [documentation](/docs/en/Model_Details/ACE-Step.md) and [example code](/examples/ace_step/).
+
 - **April 27, 2026**: We have reinstated support for the Stable Diffusion v1.5 and SDXL models, providing academic research support exclusively for these two model types.
 
 - **April 14, 2026** JoyAI-Image open-sourced, welcome a new member to the image editing model family! Support includes instruction-guided image editing, low VRAM inference, and training capabilities. For details, please refer to the [documentation](/docs/en/Model_Details/JoyAI-Image.md) and [example code](/examples/joyai_image/).

+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.

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."
