An official quantization of meta-llama/Llama-2-7b using PV-Tuning on top of AQLM.

For this quantization, we used 1 codebook of 16 bits for groups of 8 weights.

The 1x16g16 (1-bit) models are on the way, as soon as we update the inference lib with their respective kernels.

To learn more about the inference, as well as the information on how to quantize models yourself, please refer to the official GitHub repo. The original code for PV-Tuning can be found in the AQLM@pv-tuning branch.

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
