Pythia is an extensive suite designed to analyze the development and scaling of large language models (LLMs). It comprises 16 models, each trained with public data in a consistent order, featuring sizes ranging from 70 million to 12 billion parameters. The project provides public access to 154 checkpoints per model, as well as tools to reproduce training data loaders for in-depth research. Pythia aims to aid various research domains with case studies on topics like memorization, the impact of term frequency on few-shot learning, and strategies for mitigating gender bias. This carefully controlled environment offers unique insights into the training dynamics of LLMs. The suite includes trained models, analysis code, training code, and data, all accessible via its GitHub repository.
