KTO: Model Alignment as Prospect Theoretic Optimization
Paper • 2402.01306 • Published • 22
This model is a fine-tuned version of meta-llama/Llama-3.3-70B-Instruct. It has been trained using TRL.
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="None", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])
This model was trained with KTO, a method introduced in KTO: Model Alignment as Prospect Theoretic Optimization.
