Definition
Pythia is a series of open-source large language models (LLMs) created by EleutherAI, designed to facilitate research into the interpretability and behavior of neural networks. The suite includes models of varying sizes, from small 70M parameter models to larger 12B parameter versions, all based on the GPT-2 architecture but trained on the Pile dataset. Pythia models are particularly valued in the AI community for their transparency and the availability of detailed training logs, making them ideal for studying scaling laws, emergent abilities, and model internals.
Summary
Pythia is a suite of decoder-only large language models developed by EleutherAI, ranging from 70 million to 12 billion parameters.
