+# EfficientViT optimized for Arm-based Edge Linux
+
+EfficientViT image classification model, optimized with INT8 quantization and exported as an ExecuTorch program for the XNNPACK CPU backend on Arm-based platforms.
+
+This model was optimized using [Arm AI Model Optimizer](https://developer.arm.com/dev-docs/ai-model-optimizer/).
+
+## Summary
+
+This repository contains an optimized version of EfficientViT for image classification. The model is provided as an ExecuTorch `.pte` file using the XNNPACK with KleidiAI delegate, targeting Edge Linux systems. Precision: INT8 weights (quantization details not recorded in metadata).
+
+**Key results**
+
+| Area | Result |
+|---|---|
+| Model format | ExecuTorch (.pte) |
+| Target device class | Edge Linux |
+| Reference device | Raspberry Pi 5 (16GB) (Cortex-A76, 4 cores) |
+| Primary performance result | 1.24x lower p50 latency (26.01 ms to 20.90 ms) |
+| Accuracy result | Top-1 accuracy 78.68% (-0.68 pp vs. baseline) |
+| Size / memory result | 2.06x smaller model (37.39 MB to 18.12 MB), 31.69 MB peak memory |

+
+## Optimization approach
+
+| Optimization area | Applied? | Notes |
+|---|---|---|
+| Model conversion | Yes | PyTorch model exported to ExecuTorch (.pte) |
+| Quantization | Yes | INT8 weights (quantization details not recorded in metadata) |
+| Runtime/backend selection | Yes | XNNPACK with KleidiAI, 4 threads |
+| Accuracy validation | Yes | ImageNet-1k, 5000 samples |
+| Performance validation | Yes | Measured on Raspberry Pi 5 (16GB) |
+
+## Intended use
+
+This model is intended for developers evaluating image classification workloads on Arm-based Edge Linux platforms. It is suitable as a reference implementation for benchmarking, prototyping, and integration exploration.
+
+## Limitations
+
+- Performance depends on the target device, runtime version, backend support, memory configuration, and system load.
+- Accuracy was measured on a 5,000-image subset of the ImageNet-1k validation set, not the full 50,000 images.
+- This repository is not a replacement for the original model documentation.
