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.

If you enjoy our model, please give it a star on our Hugging Face repo and kindly cite our model. Your support means a lot to us. Thank you!

llama3.1-70B-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-3.1-70B-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-3.1-70B-Instruct
• Model Size: 8.03B
• Context length: 128K (reported by Meta-Llama-3.1-70B-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-3.1-70B-Instruct model. The fine-tuning algorithm used is ORPO [1].

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/Llama3.1-70B-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/Llama3.1-70B-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.
