Developed by: Castorini
Model type: An auto-regressive language model based on the transformer architecture
License: Llama 2 Community License Agreement
Finetuned from base model: Llama 2

This specific model is a 7B variant and is trained without data augmentation. It is also worth noting that it is converted to FP16.
