+
+## Introduction
+We release a state-of-the-art instruct model of its class, **SFR-Iterative-DPO-LLaMA-3-8B-R**.
+On all three widely-used instruct model benchmarks: **Alpaca-Eval-V2**, **MT-Bench**, **Chat-Arena-Hard**, our model outperforms all models of similar size (e.g., LLaMA-3-8B-it), most large open-sourced models (e.g., Mixtral-8x7B-it),
+and strong proprietary models (e.g., GPT-3.5-turbo-0613). The model is trained with open-sourced datasets without any additional human-/GPT4-labeling.

+- [Reward model](https://huggingface.co/Salesforce/SFR-RM-LLaMA-3-8B-R)
+- [RLHF model](https://huggingface.co/Salesforce/SFR-Iterative-DPO-LLaMA-3-8B-R)

+
+## Training methods
+We have developed a simple and efficient online RLHF recipe for LLM instruct training. Our recipe is DPO-based and thus much cheaper and simpler to train and tune compared to PPO-based approaches.
+Unlike widely-used offline DPO, the online component of our approach effectively mitigates distribution shifts during policy optimization.
+For a detailed exposition, please refer to our accompanying technical report.

+## Usage
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+device = "cuda" 
+
+model = AutoModelForCausalLM.from_pretrained("Salesforce/SFR-Iterative-DPO-LLaMA-3-8B-R")
+tokenizer = AutoTokenizer.from_pretrained("Salesforce/SFR-Iterative-DPO-LLaMA-3-8B-R")
+
+messages = [
+    {"role": "user", "content": "I'm trying to teach myself to have nicer handwriting. Can you help?"},
+]
+
+model_inputs = tokenizer.apply_chat_template(messages, return_tensors="pt")
+
+model_inputs = model_inputs.to(device)
+model.to(device)
+
+output_tokens = model.generate(model_inputs, max_new_tokens=1024, do_sample=True)
+model_outputs = tokenizer.batch_decode(output_tokens)
+print(model_outputs[0])
+```
+
+
+## Limitations
+SFR-Iterative-DPO-LLaMA-3-8B-R is a research model developed as part of our RLHF initiative at Salesforce. 
+While safety and ethical considerations are integral to our alignment process, 
+there remains the possibility that the model could generate offensive or unethical content, particularly under adversarial conditions. 
+We are committed to continuous improvement in our models to minimize such risks and encourage responsible usage.
