## Description

BitNet is a quantized inference engine designed to execute highly compressed language models by performing arithmetic on low-precision, bit-level weight data. It functions as a model optimization toolkit and a high-performance kernel library, enabling the execution of large language models on consumer hardware by reducing memory footprints and increasing processing speeds.

The project distinguishes itself through hardware-specific kernel optimizations that leverage native processor instructions to accelerate matrix multiplication. By utilizing packed integer arithmetic and memory-aligned weight permutation, the engine improves cache locality and computational density. These capabilities are specifically tuned to accelerate autoregressive decoding, minimizing latency during the sequential token generation process to support real-time text generation requirements.

The toolkit includes a comprehensive suite for hardware-accelerated neural computation, allowing users to benchmark inference kernels and measure generation latency against baseline implementations. These tools ensure that the inference pipeline maintains high throughput and efficiency when processing compressed models on supported graphics hardware.
