Pythia
A suite of standard GPT-NeoX-style Transformer language models released by EleutherAI. The training process is fully transparent, including a complete sequence of checkpoints, and the models are widely used as baselines in large language model research.
Timeline (last 90 days)
Pythia is a series of standard GPT-NeoX-style Transformer models released by EleutherAI, with a fully public and transparent training process.
None of the combined models exceeded the parent model Pythia on multiple-choice accuracy; some combinations matched RWKV but could not reach the level of the original Pythia.
An arXiv paper (arXiv:2609.10830) investigates membership inference using two model families with publicly known pretraining corpora—OLMo-2 and Pythia—along with a public index that can return the exact number of times a sentence appears in the corpus.
