# IPDA Debater Depth Adaptation LoRA (Iteration 1)

This is a LoRA adapter for judge depth adaptation. It trains the model to adapt debate output to judges with different expertise levels (lay → expert) across two dimensions:
- **Debate expertise**: How well the judge understands debate mechanics
- **Domain expertise**: How well the judge understands the topic

This model is a fine-tuned version of [debaterhub/ipda-debater-qwen-30b-cx](https://huggingface.co/debaterhub/ipda-debater-qwen-30b-cx).
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="None", 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).
