Pythia

Pythia is a suite of tools developed by EleutherAI for analyzing large language models. It combines interpretability analysis and scaling laws to understand how knowledge develops and evolves during training in autoregressive transformers. The aim of Pythia is to enable controlled scientific research on openly accessible and transparently trained large language models. It provides a suite of models with partially trained checkpoints for interpretability research. Additionally, Pythia includes models of different sizes trained on different datasets to facilitate interpretability analysis. With Pythia, researchers can gain insights into the inner workings of large language models and conduct in-depth analysis for various use cases.
