Open models - Language models

Because fully open science requires more than just open weights, we share all of our models with open data, code, recipes, intermediate checkpoints, and more.

Olmo 3

Our latest and greatest open language model provides the most complete model pipeline ever released, allowing for infinite customizability and contextual understanding of how to create, modify, and deploy LLMs.

Olmo 2

Meet OLMo 2, a family of 7B, 13B, and 32B models trained up to 6T tokens. Olmo 2 outperforms other contemporaneous fully open models and competes with open-weight models like Llama 3.1 8B.

Tülu 3

Tülu 3 is a leading instruction following model family, offering fully open-source data, code, and recipes designed to serve as a comprehensive guide for modern post-training techniques.

OLMoE

OLMoE is the first mixture-of-experts model to join the OLMo family. OLMoE is the first model to be on the Pareto frontier of performance and size, while also being released with open data, code, evaluations, logs, and intermediate training checkpoints. OLMoE can be trained 2x faster than equivalent dense models.
