About

Pythia 31M is an open-source large language model developed by EleutherAI, designed as part of a suite to explore interpretability, learning dynamics, and ethics in LLMs. This model employs the GPT-NeoXForCausalLM architecture with 30.5 million parameters and a context length of 2048 tokens. Trained from random weights associated with the Pythia series, it has several variants; these versions are based on different datasets such as SimpleWiki, SimplePile Lite, and GoodWiki. The model primarily focuses on text generation, with varying performances across different benchmarks compared to more extensive models like GPT-4.
