EleutherAI open-sources Bergson, a scalable data attribution library for LLMs, with an EMNLP 2026 oral paper

BlancheMinerva · x · 2026-09-29

EleutherAI researcher Blanche Minerva announced Bergson, an open-source Python library providing scalable, state-of-the-art data attribution methods for LLMs — estimating how removing training data points affects a model's behavior. It supports EK-FAC (2023), TrackStar (2024), SOURCE (2024), MAGIC (2025), ASTRA (2025), gradient cosine similarity, and more. Reproducibility is a core design goal: one-line run reproduction, reusable intermediate artifacts via CLI flags, and a CLI-or-code workflow. The companion paper will be an oral at EMNLP 2026.
