Llama-3.1-8B-Instruct-MR-GPTQ-nvfp

Model Overview

This model was obtained by quantizing the weights of Llama-3.1-8B-Instruct to NVFP4 data type. This optimization reduces the number of bits per parameter from 16 to 4.5, reducing the disk size and GPU memory requirements by approximately 72%.

Usage

MR-GPTQ quantized models with QuTLASS kernels are supported in the following integrations:

transformers with these features:
- Available in main (Documentation).
- RTN on-the-fly quantization.
- Pseudo-quantization QAT.
vLLM with these features:
- Available in this PR.
- Compatible with real quantization models from FP-Quant and the transformers integration.

Evaluation

This model was evaluated on a subset of OpenLLM v1 benchmarks and Platinum bench. Model outputs were generated with the vLLM engine.
