**Profile type:** Startup

> INT4 weight quantization for efficient LLM inference and reduced model size.

## About

Weight Quantization (INT4) focuses on optimizing large language models (LLMs) by reducing the precision of model weights to 4-bit integers. This technique significantly decreases model size and memory usage, enabling LLMs to run on devices with limited resources and accelerating inference speeds. It employs advanced quantization methods to maintain accuracy while achieving substantial compression.
