+- 🚀🚀🚀 [July 24, 2024] We now introduce [shenzhi-wang/Llama3.1-8B-Chinese-Chat](https://huggingface.co/shenzhi-wang/Llama3.1-8B-Chinese-Chat)! 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_k_m, 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](https://shenzhi-wang.netlify.app)\*, [Yaowei Zheng](https://github.com/hiyouga)\*, Guoyin Wang (in.ai), Shiji Song, Gao Huang. (\*: Equal Contribution)

+
+# 1. Introduction
+
+This is the first model specifically fine-tuned for Chinese & English users based on the [Meta-Llama-3.1-8B-Instruct model](https://huggingface.co/meta-llama/Meta-Llama-3.1-8B-Instruct). 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
+
+```python
+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
+
+```python
+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](https://huggingface.co/shenzhi-wang/Llama3.1-8B-Chinese-Chat/tree/main/gguf);
+2. Use the GGUF models with [LM Studio](https://lmstudio.ai/);
+3. You can also follow the instructions from https://github.com/ggerganov/llama.cpp/tree/master#usage to use gguf models.
