Olmo
Olmo is an open-weight language model developed by the Allen Institute for AI (Ai2) that includes publicly available training data, code, and evaluation details to enable independent research and transparency. The model has been fine-tuned by commercial labs like AISquared to create derivative products such as Bolt, and Ai2 has released subsequent versions including Olmo 3 in spring 2026 as part of its focus on long-term open AI research and development.
