Olmo

Olmo란 무엇인가요?

Olmo is Ai2's family of open language models for developers and researchers. It provides model weights alongside training data, code, and evaluation tools, allowing users to examine how models are built and adapt them to their own experiments.

The current Olmo 3 family offers 7B and 32B models with Base, Instruct, and Think variants. Instruct models support multi-turn chat and tool use; Think models expose intermediate reasoning for complex prompts. You can explore models through Ai2's Playground or use official model artifacts in your own execution environment.
