Sheared-LLaMA-2.7B-Pruned is the model pruned from [meta-llama/Llama-2-7b-hf](https://huggingface.co/meta-llama/Llama-2-7b-hf) **without continued pre-training**. 
We used roughly 0.4B tokens to perform the pruning experiment. This model could be a good use to study 
- effective data mixtures for continued pre-training
- comparisons to other pruning techniques
- extensive evaluations to understand how pruning affects knowledge and reasoning capabilities of LLMs
