# gemma-2b-orpo
This is an ORPO fine-tune of [google/gemma-2b](https://huggingface.co/google/gemma-2b) with
[`alvarobartt/dpo-mix-7k-simplified`](https://huggingface.co/datasets/alvarobartt/dpo-mix-7k-simplified).
**⚡ Quantized version (GGUF)**: https://huggingface.co/anakin87/gemma-2b-orpo-GGUF
## ORPO
[ORPO (Odds Ratio Preference Optimization)](https://arxiv.org/abs/2403.07691) is a new training paradigm that combines the usually separated phases
of SFT (Supervised Fine-Tuning) and Preference Alignment (usually performed with RLHF or simpler methods like DPO).
- Faster training
- Less memory usage (no reference model needed)
- Good results!
## 🏆 Evaluation
### Nous
gemma-2b-orpo performs well for its size on Nous' benchmark suite.

## 🎮 Model in action
### Usage notebook
[📓 Chat and RAG using Haystack](./notebooks/usage.ipynb)
### Simple text generation with Transformers
The model is small, so it runs smoothly on Colab. *It is also fine to load the model using quantization*.
```python
# pip install transformers accelerate
import torch
from transformers import pipeline
pipe = pipeline("text-generation", model="anakin87/gemma-2b-orpo", torch_dtype=torch.bfloat16, device_map="auto")
messages = [{"role": "user", "content": "Write a rap song on Vim vs VSCode."}]
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False)
outputs = pipe(prompt, max_new_tokens=500, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])
```
## Training
The model was trained using HF TRL.
[📓 Training notebook](./notebooks/training.ipynb)
### Framework versions
- Transformers 4.39.1
- Pytorch 2.2.0+cu121
- Datasets 2.18.0
