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…

Olmix: A Framework for Data Mixing Throughout LM Development

Mayee F. Chen, Tyler Murray, David Heineman +5

Data mixing -- determining the ratios of data from different domains -- is a first-order concern for training language models (LMs). While existing mixing methods show promise, the…

Fluid Language Model Benchmarking

Valentin Hofmann, David Heineman, Ian Magnusson +7

Language model (LM) benchmarking faces several challenges: comprehensive evaluations are costly, benchmarks often fail to measure the intended capabilities, and evaluation quality…

Establishing Task Scaling Laws via Compute-Efficient Model Ladders

Akshita Bhagia, Jiacheng Liu, Alexander Wettig +9

We develop task scaling laws and model ladders to predict the individual task performance of pretrained language models (LMs) in the overtrained setting. Standard power laws for la…

Signal and Noise: A Framework for Reducing Uncertainty in Language Model Evaluation

David Heineman, Valentin Hofmann, Ian Magnusson +5

Developing large language models is expensive and involves making decisions with small experiments, typically by evaluating on large, multi-task evaluation suites. In this work, we…

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…
