Llama 3.1 8B for Amharic: Vocabulary expansion

This model is built on top of Llama 3.1 8B adapted for Amharic using 500M target language tokens sampled from MADLAD-400. It has an additional target vocabulary of 10K.

Model Details

• Vocabulary: This model has an additional target vocabulary of 10K.
• Target vocabulary initialization: The target weights of the embedding and LM head were initialized using mean initialization.
• Training: This model was continually pre-trained on 500M target language tokens sampled from MADLAD-400.

Model Description

• Language: Amharic
• License: Llama 3.1 Community License Agreement
• Fine-tuned from model: meta-llama/Llama-3.1-8B
