# Superswallow-7b-v0.2

**Known Performance Issues:**

Swallow 7B's may have unstable output with `Null preset` of text-generation-webui, and this model also inherits that problem.

**Important Notice:**

This model partially utilizes the parameters of Tulu V2 DPO finetuned based on Llama 2, so it may inherit the AI2 ImpACT license. Please use the model keeping in mind that there may be changes regarding the license if AI2 contacts me.

The [AI2 ImpACT license](https://allenai.org/impact-license) includes information about data artifacts and model artifacts, but does not cover the case of directly applying parts of the LLM parameters of a model artifact to other models. However, I respect their research and great work, so I will change the license immediately if AI2 contacts me.

## Description

This is a merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit). The model was created by injecting the ability to follow user intent from [Tulu 2 DPO](https://arxiv.org/abs/2311.10702) into the [Swallow](https://zenn.dev/tokyotech_lm/articles/d6cb3a8fdfc907) instract model.

It was a proof of concept for merging LLMs trained in other languages, and paid close attention to preserving the linguistic capabilities of the merge-based model.

As far as I know, Swallow is the full set Llama 2 model(7B, 13B, 70B) that can output the most beautiful Japanese. Therefore, I used it as the base model for merging this time. Thank you for their wonderful work.

## Test environment

This model was tested using [text-generation-webui](https://github.com/oobabooga/text-generation-webui/tree/main). I use preset `simple-1` and `Null preset` for Generation.

### Recommendation

Use `simple-1` settings:
- temperature: 0.7
- top_p: 0.9
- repetition_penalty: 1.15
- top_k: 20

### Tested `temperature` Range

- temperature: 0.3 - 1.0

It works fine in most cases, but depending on the prompt, the output may become unstable at temperatures around 1.0.

### Tested `repetition_penalty` Range

- repetition_penalty: 1.0 - 1.15

It works fine in most cases, but depending on the prompt, the output may become repetition at repetition_penalty around 1.0.

## Prompt template

### Tulu Style (Recommended format)

```
<|user|>
Your message here!
<|assistant|>

```

For best results, format all inputs in this manner. **Make sure to include a newline after `<|assistant|>`, this can affect generation quality quite a bit.**

### Swallow Style (Alpaca format)

```
以下に、あるタスクを説明する指示があり、それに付随する入力が更なる文脈を提供しています。リクエストを適切に完了するための回答を記述してください。

### 指示:
