# Vicuna Chinese Replication Beta

**WARNING** This is a highly experimental beta model for research only.

With the success of [Vicuna](https://vicuna.lmsys.org/) which achieves impressive quality with mere 70K finetune data, we would like to do some preliminary experiment
to see if how much a similar Chinese dataset can boost the performance of language model.

**Data**

We use the [unfiltered ShareGPT](https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered) as the English corpus and use two difference ways to translate into Chinese
*  Simply use machine translation. The translated data are extremly noisy and contain lots of mistakes, so we only retrain a heavy filtered subset.
*  Inspired by [baize](https://github.com/project-baize/baize-chatbot), we feed the first question to ChatGPT and ask it to translate into Chinese and continue self-chatting. 
   The result is no where near as thoughtful as the real ones, we include them nevertheless.

We also include a small fraction (30k) of CoT data from FLAN and [Chinese school math](https://huggingface.co/datasets/BelleGroup/school_math_0.25M), resulting a total of 150k training data.



**Model**

We use [Chinese-LLaMA-13B](https://huggingface.co/ziqingyang/chinese-llama-lora-13b) as the base model. It is continue-trained from LLaMA on Chinese corpus with no instruction finetune.

We follow exactly the same settings as Vicuna for finetune.

**Result**

Comparing with Alpaca-like model, the Vicuna replication tends to generate longer and more detailed answers. However it also comes with **more severe hallucinations** and being US-centric. Please check the examples below.

We try to use ChatGPT to score the answers, however we found ChatGPT has a strong tendency to give high scores to more detailed answer even it contains mistake, making the score unreliable.
