Model Card for Deita 7B V1.0

GitHub | Paper

Deita is an open-sourced project designed to facilitate Automatic Data Selection for instruction tuning in Large Language Models (LLMs). Deita 7B V1.0 is a fine-tuned + DPO version of Mistral-7B-v0.1 that was trained on 6K automatically selected lightweight, high-quality alignment SFT data: Deita 6K V0 and 10K randomly sampled alignment preference data from Ultrafeedback.

Model description

• Model type: Model trained on automatically selected lightweight, high-quality alignment SFT data and 10K randomly sampled alignment preference data.
• Language(s) (NLP): Primarily English
• Finetuned from model: Mistral-7B-v0.1

Model Sources

• Repository: https://github.com/hkust-nlp/deita
• Model Family: Other models and the dataset are found in the Deita collection.

Performance

Input Format

The model is trained using the vicuna_v1.1 template

SFT Format

A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: Hello! ASSISTANT: Hi!</s>USER: How are you? ASSISTANT:

DPO Format

A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: <prompt> ASSISTANT: <answer></s>

where <answer> can be a chosen answer or a rejected answer.
