Model Overview

This model is an aligned version of meta-llama/Meta-Llama-3-8B. We apply the following pipeline:

• We first use Magpie-Align/Magpie-Pro-MT-300K-v0.1 dataset and perform SFT -> Magpie-Align/Llama-3-8B-Magpie-Align-SFT-v0.1
• We then perform DPO on the princeton-nlp/llama3-ultrafeedback dataset.

The overall performance is even better than the official Llama-3-8B-Instruct Model!

• Alpaca Eval 2 (vs GPT-4-Turbo-1106): 38.52 (LC), 38.47 (WR)
• Alpaca Eval 2 (vs Llama-3-8B-Instruct): 69.37 (LC), 70.05 (WR)
• Arena Hard: 32.4
• WildBench: 39.3 ((was) Best <30B Model! 🏆)
• Zero-Eval GSM: 54.62

Model Performance

We compare our Llama-3-8B-Magpie-Align with official and other open-aligned LLMs that have been fine-tuned from base models and have publicly released their training datasets. The results are as follows:
