Olmo 3

Team Olmo, :, Allyson Ettinger +66

We introduce Olmo 3, a family of state-of-the-art, fully-open language models at the 7B and 32B parameter scales. Olmo 3 model construction targets long-context reasoning, function…

Extracting Rule-based Descriptions of Attention Features in Transformers

Dan Friedman, Adithya Bhaskar, Alexander Wettig +1

Mechanistic interpretability strives to explain model behavior in terms of bottom-up primitives. The leading paradigm is to express hidden states as a sparse linear combination of…

Cache Me If You Can: How Many KVs Do You Need for Effective Long-Context LMs?

Adithya Bhaskar, Alexander Wettig, Tianyu Gao +2

Language models handle increasingly long contexts for tasks such as book summarization, but this leads to growing memory costs for the key-value (KV) cache. Many prior works have p…

SWE-smith: Scaling Data for Software Engineering Agents

John Yang, Kilian Lieret, Carlos E. Jimenez +7

Despite recent progress in Language Models (LMs) for software engineering, collecting training data remains a significant pain point. Existing datasets are small, with at most 1,00…

Lugha-Llama: Adapting Large Language Models for African Languages

Happy Buzaaba, Alexander Wettig, David Ifeoluwa Adelani +1

Large language models (LLMs) have achieved impressive results in a wide range of natural language applications. However, they often struggle to recognize low-resource languages, in…

Organize the Web: Constructing Domains Enhances Pre-Training Data Curation

Alexander Wettig, Kyle Lo, Sewon Min +3

Modern language models are trained on large, unstructured datasets consisting of trillions of tokens and obtained by crawling the web. The unstructured nature makes it difficult to…
