# gemma-4-E2B-it-q4.apml — Apertura model bundle

Gemma 4 E2B (elastic 2B) instruction-tuned, quantized to the **Apertura
`.apml` bundle format**: MLX-affine 4-bit (group size 64, 8-bit embeddings),
`tokenizer.json` + `chat_template.jinja` included, runtime `mlx`,
architecture `gemma4`. Post-training quantization of the bf16 release (this
family has no QAT variant).

Consumed by [Apertura](https://github.com/apocryphx/Apertura) — an
Objective-C++ transformer engine + macOS chat app on MLX. Export gate:
`--verify-bundle` (bundle reload == in-memory quantization, argmax-identical).
