Libraries

How to use NLP-Final-Project/phi-2-dpo with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="NLP-Final-Project/phi-2-dpo")

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("NLP-Final-Project/phi-2-dpo")
model = AutoModelForCausalLM.from_pretrained("NLP-Final-Project/phi-2-dpo", device_map="auto")

Model Card for phi-2-dpo

This model is a fine-tuned version of NLP-Final-Project/phi-2-sft. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="NLP-Final-Project/phi-2-dpo", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])

Training procedure

This model was trained with DPO, a method introduced in Direct Preference Optimization: Your Language Model is Secretly a Reward Model.

Framework versions

TRL: 1.3.0
Transformers: 5.7.0
Pytorch: 2.11.0
Datasets: 4.8.5
Tokenizers: 0.22.2
