# Superswallow-13b-v0.1

**Known Performance Issues**

Two potential bugs have been found in this model:
- **NEED `repetition_penalty`**
- **NEED high `temperature`**

These issue may be caused by the self-attention layers and will be fixed in the next version. (However, I don't know if the benchmark score will improve)

**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` for Generation.

Users reported that setting **repetition_penalty** is important to prevent repeated output. If you run into any issues, be sure to check your settings. Additionally, a bug was discovered that caused an error at low temperatures.

- **temperature: 0.7**
- top_p: 0.9
- **repetition_penalty: 1.15**
- top_k: 20
