# CosyVoice.cpp Windows Vulkan Community Runtime

Windows x64 runtime for compatible CosyVoice GGUF models, with Vulkan and CPU backends. Models and voices are downloaded separately from [upstream](https://huggingface.co/Lourdle/Fun-CosyVoice3-0.5B-2512-GGUF).

New files are grouped under version directories. The legacy release retains its original root URLs; existing version assets are immutable.

Extract the full package and keep its DLLs together. A compatible Vulkan driver and Microsoft Visual C++ x64 runtime may be required. CPU and RX 9070/Vulkan have limited validation; other hardware is unverified. The sampling correction does not guarantee artifact-free speech or eliminate all silent failures. Remaining streaming click/loudness and F32 allocation limitations are documented in each version's notes.

Core and bundled dependencies retain their respective licenses. See [LICENSE](LICENSE) and [third-party notices](THIRD_PARTY_NOTICES.md). This is an unofficial community runtime, not an upstream or AMD release.

## Version compatibility notice

Releases before 20261024-01 retain the earlier silent-token handling and can fail with empty PCM in affected states. The latest version separates generated and emitted speech tokens; it does not guarantee artifact-free output.
