This provides open-source language models for researchers and developers, though it appears incremental as an improved release of existing model families.

The authors introduced Olmo 3, a family of fully-open language models at 7B and 32B scales targeting tasks like long-context reasoning and coding, with their flagship Olmo 3 Think 32B claimed as the strongest fully-open thinking model to date.

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 calling, coding, instruction following, general chat, and knowledge recall. This release includes the entire model flow, i.e., the full lifecycle of the family of models, including every stage, checkpoint, data point, and dependency used to build it. Our flagship model, Olmo 3 Think 32B, is the strongest fully-open thinking model released to-date.
