Pythia is a suite of 16 open-source autoregressive transformer language models from EleutherAI, ranging in size from 70 million to 12 billion parameters. All models were trained on the exact same data (the Pile dataset) in identical order to enable scientific research on the interpretability and learning dynamics of LLMs. For each of the 16 models, 154 training checkpoints are publicly released, allowing analysis of model development throughout training. Pythia is freely available under the Apache 2.0 license and is designed primarily for research purposes rather than commercial production use.
