This is phi-3-mini-4k-instruct ORPO finetuning for the italian language over the Alpaca vs. Alpaca italian dataset: efederici/alpaca-vs-alpaca-orpo-dpo

Model Details

Model Description

• Developed by: Diego Giorgini
• Funded by: AI Technologies SRL - www.aitechnologies.it
• Language(s) (NLP): Italian
• License: llama3
• Finetuned from model: unsloth/Phi-3-mini-4k-instruct

Training Details

Environment

unsloth: 2024.5
torch: 2.2

Training Data

efederici/alpaca-vs-alpaca-orpo-dpo: The Alpaca vs. Alpaca dataset is a curated blend of the Alpaca dataset and the Alpaca GPT-4 dataset, both available on HuggingFace Datasets. It uses the standard GPT dataset as the 'rejected' answer, steering the model towards the GPT-4 answer, which is considered as the 'chosen' one.

Training Procedure

Preprocessing [optional]

• No preprocessing has been performed, except for formatting with the phi-3 chat_template from unsloth:

  tokenizer = get_chat_template(tokenizer, chat_template = "phi-3")
