# gemma-4-31b-it-qat-q4.apml — Apertura model bundle

Gemma 4 31B instruction-tuned, Google's QAT-Q4 weights converted to the
**Apertura `.apml` bundle format**: MLX-affine 4-bit quantization
(group size 64, 8-bit embeddings), `tokenizer.json` +
`chat_template.jinja` included, runtime `mlx`, architecture `gemma4`.

Consumed by [Apertura](https://github.com/apocryphx/Apertura) — an
Objective-C++ transformer engine + macOS chat app on MLX.
