# Peach-9B-8k-Roleplay

Peach-9B-8k-Roleplay is a chat large language model obtained by finetuning [01-ai/Yi-1.5-9B](https://huggingface.co/01-ai/Yi-1.5-9B) model on more than 100K conversations created through our data synthesis approach. 

## How to start
The version of Transformers we are using is as follows, but a newer version may be available.
```
torch==1.13.1
gradio==3.50.2
transformers==4.37.2
```

Then run the following code to infer.

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name_or_path = "losed-Character/Peach-9B-8k-Roleplay"
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True, return_tensors="pt")
model = AutoModelForCausalLM.from_pretrained(
    model_name_or_path, torch_dtype=torch.bfloat16, 
    trust_remote_code=True, device_map="auto")
messages = [
    {"role": "system", "content": "你是黑丝御姐"},
    {"role": "user", "content": "你好，你是谁"},
]
input_ids = tokenizer.apply_chat_template(conversation=messages, tokenize=True)
output = model.generate(
    inputs=input_ids, 
    temperature=0.3, 
    top_p=0.5, 
    no_repeat_ngram_size=6,
    repetition_penalty=1.1,
    max_new_tokens=512)
print(tokenizer.decode(output[0]))

```

Or you can just use below code to run web demo.
```
python demo.py
```
