For optimal performance, we refrain from fine-tuning the model's identity. Thus, inquiries such as "Who are you" or "Who developed you" may yield random responses that are not necessarily accurate.

Updates

• 🚀🚀🚀 [July 24, 2024] We now introduce shenzhi-wang/Llama3.1-8B-Chinese-Chat! Compared to the original Meta-Llama-3.1-8B-Instruct model, our llama3.1-8B-Chinese-Chat model significantly reduces the issues of "Chinese questions with English answers" and the mixing of Chinese and English in responses. The training dataset contains >100K preference pairs, and it exhibits significant enhancements, especially in roleplay, function calling, and math capabilities!
• 🔥 We provide the official q4_0, q8_0, and f16 GGUF versions of Llama3.1-8B-Chinese-Chat-v2.1 at https://huggingface.co/shenzhi-wang/Llama3.1-8B-Chinese-Chat/tree/main/gguf!

Model Summary

llama3.1-8B-Chinese-Chat is an instruction-tuned language model for Chinese & English users with various abilities such as roleplaying & tool-using built upon the Meta-Llama-3.1-8B-Instruct model.

Developers: Shenzhi Wang*, Yaowei Zheng*, Guoyin Wang (in.ai), Shiji Song, Gao Huang. (*: Equal Contribution)

• License: Llama-3.1 License
• Base Model: Meta-Llama-3.1-8B-Instruct
• Model Size: 8.03B
• Context length: 128K (reported by Meta-Llama-3.1-8B-Instruct model, untested for our Chinese model)

1. Introduction

This is the first model specifically fine-tuned for Chinese & English users based on the Meta-Llama-3.1-8B-Instruct model. The fine-tuning algorithm used is ORPO [1].

Compared to the original Meta-Llama-3.1-8B-Instruct model, our llama3.1-8B-Chinese-Chat model significantly reduces the issues of "Chinese questions with English answers" and the mixing of Chinese and English in responses.

2. Usage

2.1 Usage of Our BF16 Model

1. Please upgrade the transformers package to ensure it supports Llama3.1 models. The current version we are using is 4.43.0.

2. Use the following Python script to download our BF16 model

from huggingface_hub import snapshot_download
snapshot_download(repo_id="shenzhi-wang/Llama3.1-8B-Chinese-Chat", ignore_patterns=["*.gguf"])  # Download our BF16 model without downloading GGUF models.

3. Inference with the BF16 model

import torch
import transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "/Your/Local/Path/to/Llama3.1-8B-Chinese-Chat"
dtype = torch.bfloat16

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    device_map="cuda",
    torch_dtype=dtype,
)

chat = [
    {"role": "user", "content": "写一首关于机器学习的诗。"},
]
input_ids = tokenizer.apply_chat_template(
    chat, tokenize=True, add_generation_prompt=True, return_tensors="pt"
).to(model.device)

outputs = model.generate(
    input_ids,
    max_new_tokens=8192,
    do_sample=True,
    temperature=0.6,
    top_p=0.9,
)
response = outputs[0][input_ids.shape[-1] :]
print(tokenizer.decode(response, skip_special_tokens=True))

2.2 Usage of Our GGUF Models

1. Download our GGUF models from the gguf_models folder;
2. Use the GGUF models with LM Studio;
3. You can also follow the instructions from https://github.com/ggerganov/llama.cpp/tree/master#usage to use gguf models.
