# gemma-4-E2B-it-q4.apml — Apertura model bundle
|
| 13 |
+
|
| 14 |
+
Gemma 4 E2B (elastic 2B) instruction-tuned, quantized to the **Apertura
|
| 15 |
+
`.apml` bundle format**: MLX-affine 4-bit (group size 64, 8-bit embeddings),
|
| 16 |
+
`tokenizer.json` + `chat_template.jinja` included, runtime `mlx`,
|
| 17 |
+
architecture `gemma4`. Post-training quantization of the bf16 release (this
|
| 18 |
+
family has no QAT variant).
|
| 19 |
+
|
| 20 |
+
Consumed by [Apertura](https://github.com/apocryphx/Apertura) — an
|
| 21 |
+
Objective-C++ transformer engine + macOS chat app on MLX. Export gate:
|
| 22 |
+
`--verify-bundle` (bundle reload == in-memory quantization, argmax-identical).
