## Model Description

- **Fine-Tuned from Model:** [Qwen/Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct)

## Model Summary

This is a fine-tuned Qwen2.5-7B-Instruct model on the [Egida-DPO-Qwen2.5-7B-Instruct](https://huggingface.co/datasets/HPAI-BSC/Egida/viewer/Egida-DPO-Qwen2.5-7B-Instruct) dataset.

The [Egida](https://huggingface.co/datasets/HPAI-BSC/Egida/viewer/Egida?views%5B%5D=egida_full) dataset is a collection of adversarial prompts that are thought to ellicit unsafe behaviors from language models. Specifically for this case, the Egida train split is used to run inference on Qwen2.5-7B-Instruct. Unsafe answers are selected, and paired with safe answers to create a customized DPO
dataset for this model. This results in a DPO dataset composed by triplets < ”question”, ”chosen answer”, ”discarded answer” > which contain questions that elicit unsafe responses by this target model, as well as the unsafe responses produced by it.

## Training Details

- **Hardware:** NVIDIA H100 64 GB GPUs
- **Devices:** 4 GPUs (1 node)
- **Time:** 1.59h
- **Batch Size:** 8
- **LR:** 10−7
