Qwen3-1.7B-Q4 - Optimized 4-bit ONNX for Mobile

This repository contains a highly optimized 4-bit quantized version of Qwen3-1.7B, specifically tailored for local inference on mid-range Android hardware.

🚀 Mobile Optimization Highlights

Unlike standard exports, this version was built to maximize the throughput of the XNNPACK execution provider on ARM-based chipsets (like the Dimensity 6300).

• Memory Mapping (mmap): Configured for zero-copy loading using MappedByteBuffer, allowing a 1.31GB model to run on devices with limited RAM without triggering the Android OOM (Out of Memory) killer.
• Tensor Alignment: Optimized for block size 32 to ensure efficient cache line usage on Cortex-A76/A55 architectures.
