It supports both ground-truth F0-based singing synthesis and explicit pitch prediction in TTS. [AudioGPT](https://huggingface.co/spaces/AIGC-Audio/AudioGPT) reports 10k GitHub stars, 850 forks, and 53 open issues, last pushed Jul 6, 2024. [DiffSinger](https://github.com/MoonInTheRiver/DiffSinger) has 4.8k stars, 826 forks, and 53 open issues, last pushed Jul 24, 2026.
