  # Pythia: Interpreting Transformers Across Time and Scale
  
  This repository is for EleutherAI's project *Pythia* which combines interpretability analysis and scaling laws to understand how knowledge develops and evolves during training in autoregressive transformers. For detailed info on the models, their training, and their properties, please see our paper Pythia: A Suite for Analyzing Large Language Models Across Training and Scaling.

  # Pythia: A Suite for Analyzing Large Language Models Across Training and Scaling
  
  EleutherAI's Pythia project provides the world's most comprehensive suite of openly trained autoregressive transformers, featuring 154 checkpoints saved throughout training for each model size. This enables unprecedented research into LLM interpretability, learning dynamics, and causal interventions, offering full reproducibility of results and data. For detailed info, see our paper: Pythia: A Suite for Analyzing Large Language Models Across Training and Scaling.
