Overview

Tensor library for machine learning on edge devices

✓ Optimized C/C++ implementation for CPU inference on devices with minimal memory footprint
✓ Quantization support reduces model size by 75% while maintaining acceptable accuracy
✓ Zero external dependencies enables seamless deployment across heterogeneous edge hardware
✓ Active community with 15k+ stars demonstrates proven production-grade stability and ongoing support

✗ Steeper learning curve than high-level frameworks; requires understanding of tensor operations and memory management
✗ Limited GPU acceleration compared to frameworks like PyTorch or TensorRT, primarily CPU-focused
