Model Card for Deita 7B V1.0
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.
