# Model Card

This model is pretrained as a reference baseline to the Based model provided here: https://huggingface.co/hazyresearch/based-1b-50b. 

Both checkpoints are pretrained on **50Bn tokens** of the Pile in the exact same data order using next token prediction. 


### Model Sources

The model is a standard Transformer model, using the Llama architecture (Rotary encodings, SwiGLU, RMS Norm, etc.)

The training code is provided here and can be used to reproduce training: https://github.com/HazyResearch/based

The paper for the work is here, and the appendix includes additional experimental details/hyperparameters: https://arxiv.org/abs/2402.18668


### Uses

The purpose of this work is to evaluate the language modeling quality of a new efficient architecture, Based. 

We include a series of benchmarks that you can use to evaluate quality: 
- FDA: https://huggingface.co/datasets/hazyresearch/based-fda
- SWDE: https://huggingface.co/datasets/hazyresearch/based-swde
- SQUAD: https://huggingface.co/datasets/hazyresearch/based-squad
