# acestep — runtime + GGUF weights mirror

Files needed by the local music generation feature of the KakaoWork desktop app.
This repository is a **mirror kept for build reproducibility**: the app pins a
sha256 for every file, so it needs a location whose bytes never change.

## Contents

### Runtime (built by us)

`acestep.cpp` has no upstream release artifacts, so we build it ourselves.

| File | Platform |
| --- | --- |
| `acestep-darwin-arm64.zip` | macOS arm64 (ad-hoc signed) |
| `acestep-win-x64.zip` | Windows x64 (signed) |

Each archive is flat: `ace-lm`, `ace-synth` and the ggml shared libraries sit at
the top level. The executables resolve the libraries next to them, so keep them
in one directory.

### Weights (mirrored, byte-identical)

Re-uploaded unchanged from
[Serveurperso/ACE-Step-1.5-GGUF](https://huggingface.co/Serveurperso/ACE-Step-1.5-GGUF).
Only the four files our app loads are mirrored; that repository has many more
quantizations and is the place to look for them.

| File | Size | sha256 |

| `Qwen3-Embedding-0.6B-Q8_0.gguf` | 784 MB | `972f23255e46adfe744a0eb9a0039f3c63988f65753b0968d776e8b27168c321` |

The sha256 values are the upstream ones — verify against the source repository
if you want to confirm nothing was altered in transit.
