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. Only the four files our app loads are mirrored; that repository has many more quantizations and is the place to look for them.

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