What it does
- Audience
- The current release is mainly intended for researchers and developers familiar with GPU servers and basic Docker and CUDA workflows.checked 12 Oct 2026
- Commercial use
- Nochecked 22 Sep 2026
- Compatibility limitation
- Generation quality can vary with GPU architecture and software versions, and the project says bit-identical output across GPU types is not guaranteed.checked 12 Oct 2026
- Deployment
- The repository provides Docker-based setup instructions and a local web UI.checked 12 Oct 2026
- Former name
- The project was formerly called Khala and has been officially renamed Shao.checked 12 Oct 2026
- Full-song generation
- It is designed to generate full-length musical works rather than short clips or loop-style accompaniment.checked 12 Oct 2026
- Generation architecture
- Its pipeline uses a 64-layer residual vector quantization acoustic-token hierarchy, followed by a super-resolution model and decoder.checked 12 Oct 2026
- Generation controls
- Natural-language prompts and lyrics can control style, mood, vocals, and content.checked 12 Oct 2026
- Generation pipeline
- Its pipeline generates coarse acoustic tokens, completes higher RVQ token layers with a super-resolution model, and decodes the waveform.checked 12 Oct 2026
- GPU requirement
- The full inference pipeline recommends an NVIDIA GPU with at least 24 GB of VRAM, such as an RTX 4090 or higher-tier GPU.checked 12 Oct 2026
- GPU requirements
- The full inference pipeline recommends an NVIDIA GPU with at least 24 GB of VRAM, such as an RTX 4090 or higher-tier GPU.checked 12 Oct 2026
- Included system
- The project includes a frontend UI, FastAPI backend dispatcher, single-GPU inference worker, model loading, and an end-to-end audio-generation path.checked 12 Oct 2026
- Intended users
- The current release is mainly intended for researchers and developers familiar with GPU servers.checked 12 Oct 2026
- Model license
- The linked model weights are listed as CC BY-NC 4.0.checked 12 Oct 2026
- Model weights license
- The model weights are stated to be intended for release under CC BY-NC 4.0.checked 12 Oct 2026
- Name change
- The project was formerly called Khala and has been officially renamed to Shao, with its model, codebase, and research direction unchanged.checked 12 Oct 2026
- Prompt controls
- Natural-language prompts and lyrics can control style, mood, vocals, and content.checked 12 Oct 2026
- Purpose
- Shao is a high-fidelity music-generation system that creates complete musical works from text descriptions and lyrics.checked 12 Oct 2026
- Quality limitation
- The project says inference quality is sensitive to GPU architecture, CUDA stack, container image, and Megatron/TransformerEngine versions, and bit-identical output across GPU types is not guaranteed.checked 12 Oct 2026
- Runtime dependencies
- The documented runtime uses Docker, NVIDIA Container Toolkit, and a CUDA-compatible NVIDIA driver.checked 12 Oct 2026
- Support
- The README invites users to join a WeChat group for discussion, usage questions, and future updates.checked 12 Oct 2026
- System components
- The system includes a frontend UI, FastAPI backend dispatcher, and single-GPU inference worker.checked 12 Oct 2026
- Verified environments
- The released pipeline is reported to produce normal results on an H800 with the reference image and to work on an RTX 4090 when the provided environment is followed.checked 12 Oct 2026
