Efficient inference library for quantized LLMs

⭐ 5k+ stars 📜 Open Source 🏷️ ai-tools

Overview

Efficient inference library for quantized LLMs

✓ Exceptional inference speed through 4-bit quantization without sacrificing model quality
✓ Low memory footprint enables running 70B+ parameter models on consumer GPUs
✓ Supports multiple quantization formats including GPTQ and EXL2 for flexibility
✓ Active community maintains model compatibility and provides optimized inference kernels

✗ Steep learning curve for users unfamiliar with quantization techniques and CUDA optimization
✗ Limited to Linux/Windows; macOS support is incomplete and performance is suboptimal
