## Introduction

This model is quantized version of linear merge of [mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) and [daisd-ai/anydef-orpo-v2](https://huggingface.co/daisd-ai/anydef-orpo-v2).

## Merging

Models were merged to improve quality of the final model ([idea](https://www.reddit.com/r/LocalLLaMA/comments/1fyx27y/im_pretty_happy_with_how_my_method_worked_out/)) and prevent huge losses during quantization. Merging was done using [mergekit](https://github.com/arcee-ai/mergekit) with following spec: 
```yaml
models:
  - model: mistralai/Mistral-7B-v0.1
    parameters:
      weight: 0.3
  - model: daisd-ai/anydef-orpo-v2
    parameters:
      weight: 0.7
merge_method: linear
dtype: bfloat16
```

## Quantization

The quantization was applied using [LLM Compressor](https://github.com/vllm-project/llm-compressor) with 512 random examples from [anydef-kilt-tasks-v2](https://huggingface.co/datasets/daisd-ai/anydef-kilt-tasks-v2) dataset.
We tested other numbers of examples, but did not see noticeable improvement with higher number of examples during quantization.

The recipe for quantization:
```python
recipe = [
    SmoothQuantModifier(smoothing_strength=0.8),
    GPTQModifier(targets="Linear", scheme="W4A16", ignore=["lm_head"]),
]
```
