Hubble: a Model Suite to Advance the Study of LLM Memorization

Johnny Tian-Zheng Wei, Ameya Godbole, Mohammad Aflah Khan +7

We present Hubble, a suite of fully open-source large language models (LLMs) for the scientific study of LLM memorization. Hubble models come in standard and perturbed variants: st…

TokenSmith: Streamlining Data Editing, Search, and Inspection for Large-Scale Language Model Training and Interpretability

Mohammad Aflah Khan, Ameya Godbole, Johnny Tian-Zheng Wei +5

Understanding the relationship between training data and model behavior during pretraining is crucial, but existing workflows make this process cumbersome, fragmented, and often in…

Teaching Models to Understand (but not Generate) High-risk Data

Ryan Wang, Matthew Finlayson, Luca Soldaini +2

Language model developers typically filter out high-risk content -- such as toxic or copyrighted text -- from their pre-training data to prevent models from generating similar outp…

Robust Data Watermarking in Language Models by Injecting Fictitious Knowledge

Xinyue Cui, Johnny Tian-Zheng Wei, Swabha Swayamdipta +1

Data watermarking in language models injects traceable signals, such as specific token sequences or stylistic patterns, into copyrighted text, allowing copyright holders to track a…

Interrogating LLM design under a fair learning doctrine

Johnny Tian-Zheng Wei, Maggie Wang, Ameya Godbole +2

The current discourse on large language models (LLMs) and copyright largely takes a "behavioral" perspective, focusing on model outputs and evaluating whether they are substantiall…

Verify with Caution: The Pitfalls of Relying on Imperfect Factuality Metrics

Ameya Godbole, Robin Jia

Improvements in large language models have led to increasing optimism that they can serve as reliable evaluators of natural language generation outputs. In this paper, we challenge…
