Example use

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("gabrielloiseau/TAROT-DPO")
model = AutoModelForCausalLM.from_pretrained("gabrielloiseau/TAROT-DPO")

paragraph = """I had dinner at Bella's Bistro last night, and it was a delightful experience. 
As soon as I walked in, I was greeted warmly by the hostess, and the cozy, rustic decor made me feel right at home. 
I started with the bruschetta, which was so fresh and flavorful—I could have eaten a whole meal of just that!"""
