# Model Card for pythia-1b-orpo-tldr

This model is a fine-tuned version of [cleanrl/EleutherAI_pythia-1b-deduped__sft__tldr](https://huggingface.co/cleanrl/EleutherAI_pythia-1b-deduped__sft__tldr).
It has been trained using [TRL](https://github.com/huggingface/trl).

## Quick start

```python
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="Eehan/pythia-1b-orpo-tldr", 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 ORPO, a method introduced in [ORPO: Monolithic Preference Optimization without Reference Model](https://huggingface.co/papers/2403.07691).
