z-lab/Llama-2-7b-hf-PARO
z-lab/Llama-2-7b-hf-PARO is a 4-bit quantized version of the Llama-2-7b-hf model, developed by z-lab using the ParoQuant method. ParoQuant is an INT4 quantization technique designed to minimize the accuracy gap with FP16 models while maintaining near-AWQ inference speeds. This model is optimized for efficient inference of large language models on NVIDIA GPUs and Apple Silicon, making it suitable for resource-constrained environments.
