DR Tulu: Reinforcement Learning with Evolving Rubrics for Deep Research

Rulin Shao, Akari Asai, Shannon Zejiang Shen +18

Deep research agents perform multi-step research to produce long-form, well-attributed answers. However, most open deep research agents are trained on easily verifiable short-form…

The Curious Case of Factuality Finetuning: Models' Internal Beliefs Can Improve Factuality

Benjamin Newman, Abhilasha Ravichander, Jaehun Jung +5

Language models are prone to hallucination - generating text that is factually incorrect. Finetuning models on high-quality factual information can potentially reduce hallucination…

The Delta Learning Hypothesis: Preference Tuning on Weak Data can Yield Strong Gains

Scott Geng, Hamish Ivison, Chun-Liang Li +4

Improvements in language models are often driven by improving the quality of the data we train them on, which can be limiting when strong supervision is scarce. In this work, we sh…

Precise Information Control in Long-Form Text Generation

Jacqueline He, Howard Yen, Margaret Li +7

A central challenge in language models (LMs) is faithfulness hallucination: the generation of information unsubstantiated by input context. To study this problem, we propose Precis…

A False Sense of Privacy: Evaluating Textual Data Sanitization Beyond Surface-level Privacy Leakage

Rui Xin, Niloofar Mireshghallah, Shuyue Stella Li +6

Sanitizing sensitive text data typically involves removing personally identifiable information (PII) or generating synthetic data under the assumption that these methods adequately…

ParaPO: Aligning Language Models to Reduce Verbatim Reproduction of Pre-training Data

Tong Chen, Faeze Brahman, Jiacheng Liu +5

Language models (LMs) can memorize and reproduce segments from their pretraining data verbatim even in non-adversarial settings, raising concerns about copyright, plagiarism, priva…

DataDecide: How to Predict Best Pretraining Data with Small Experiments

Ian Magnusson, Nguyen Tai, Ben Bogin +10

Because large language models are expensive to pretrain on different datasets, using smaller-scale experiments to decide on data is crucial for reducing costs. Which benchmarks and…

OLMoTrace: Tracing Language Model Outputs Back to Trillions of Training Tokens

Jiacheng Liu, Taylor Blanton, Yanai Elazar +28

We present OLMoTrace, the first system that traces the outputs of language models back to their full, multi-trillion-token training data in real time. OLMoTrace finds and shows ver…

Large-Scale Data Selection for Instruction Tuning

Hamish Ivison, Muru Zhang, Faeze Brahman +2

Selecting high-quality training data from a larger pool is a crucial step when instruction-tuning language models, as carefully curated datasets often produce models that outperfor…

2 OLMo 2 Furious

Team OLMo, Pete Walsh, Luca Soldaini +40

We present OLMo 2, the next generation of our fully open language models. OLMo 2 includes a family of dense autoregressive language models at 7B, 13B and 32B scales with fully rele…
