Official quantization of [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) using [PV-Tuning](https://arxiv.org/abs/2405.14852) on top of [AQLM](https://arxiv.org/abs/2401.06118).

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

Results (0-shot `acc`): 

Results: 
| Model      | Quantization | WikiText-2 | C4 | Model size, Gb |
|------|------|-------|------|------|
| [microsoft/Phi-3-medium-4k-instruct](https://huggingface.co/microsoft/Phi-3-medium-4k-instruct) | None |  |  | 27.9 |
|  | [1x16g8 (2-bit, model link)](https://huggingface.co/ISTA-DASLab/Phi-3-medium-4k-instruct-AQLM-PV-2Bit-1x16-hf) | 5.18	|  8.56 | 4.2Gb |
|  | [1x16g16 (1-bit, this model)](https://huggingface.co/ISTA-DASLab/Phi-3-medium-4k-instruct-AQLM-PV-1Bit-1x16-hf) | 7.42	| 10.40  | 2.7Gb |

Phi-3-**medium** is not included in the original [PV-Tuining paper](https://arxiv.org/abs/2405.14852). As of yet, we did not have the bandwidth to evaluate it properly. We hope to eventually run the zero-shot evaluation suite, or you can help us by running it yourself and opening a pull-request to the readme!

In general, we always recommend the 2-bit models for best accuracy-size trade-offs. If tempted to use the 1-bit model, try a smaller model ,
e.g. Phi-3-**mini** quantized with AQLM+PV [(quantized model link)](https://huggingface.co/ISTA-DASLab/Phi-3-mini-4k-instruct-AQLM-PV-2Bit-1x16-hf) and compare the results, or check our [AQLM+PV collection](https://huggingface.co/collections/ISTA-DASLab/aqlmpv-66564dff5d84f00a893ba93f) for a more appropriate size.
