Third-party licenses
June 23, 2026 · View on GitHub
transcribe.cpp is MIT-licensed (see LICENSE). It vendors and links
the third-party components below, each under its own permissive license. The
authoritative license text for each ships in-tree at the path noted; copies are
reproduced here for convenience.
| Component | License | Vendored at | Pin |
|---|---|---|---|
| ggml | MIT | ggml/LICENSE | see ggml/UPSTREAM |
| miniz | MIT | src/third_party/miniz/LICENSE | see src/third_party/miniz/UPSTREAM |
Prebuilt artifacts (the Swift xcframework, the native Python wheels, and the
npm platform packages) carry these same texts alongside the binaries — see each
binding's packaging for the bundled LICENSE.ggml / LICENSE.miniz files.
ggml
The tensor library underlying transcribe.cpp. Vendored under ggml/.

miniz
A single-file deflate/inflate (zlib-subset) codec. transcribe.cpp uses it only
for Whisper's temperature-fallback compression-ratio heuristic; it replaces the
previous system-zlib dependency. Vendored under src/third_party/miniz/.
miniz is MIT-licensed. (The comment block at the top of the amalgamated
miniz.c / miniz.h still reads "public domain" — a stale artifact from the
project's pre-relicensing history; upstream's current and authoritative license
is the MIT text below, also shipped at src/third_party/miniz/LICENSE.)
