# Windy Core — ggml q5_1 (mobile build)

**Windstorm Labs is the origin of record for this artifact.** It is created
here and promoted downstream; it is never edited anywhere else.

`whisper.cpp` / `whisper.rn` build of Windy Core, quantized to **q5_1** so it runs
on phones and tablets.

## Promotion path

`WindstormLabs` (here, origin) -> `WindyWord` (product) -> `WindyWordMobileApp` (mobile).

Downstream copies are **push-only**. Fix weights here, never downstream.

## Honesty note

Distinct weights from upstream (different SHA-256). On short clean English
clips the smaller models can be indistinguishable from stock Whisper — a
formal bake-off has **not** been run. Do not claim quality gains without one.

Clinic patient file: `sneakyfree/Windy-Clinic` -> `stt-models/windy-core.json`

## Licence

Upstream base is **apache-2.0** on Hugging Face, verified against the source repo we converted from. Note OpenAI's Whisper *GitHub* repo states MIT while its HF model cards state Apache-2.0; we follow the HF distribution point, since that is what we actually pulled. Windy weights are a derivative and are distributed under the same terms, with attribution upstream.
