Olmo 3
Olmo 3 is Ai2's fully open model family in 7B and 32B sizes, shipped as Base, Instruct, Think and RL Zero variants with a 65K context window. Ai2 releases the whole model flow rather than just weights: the Dolma 3 corpus, every training stage, checkpoints and code, all Apache 2.0, and the 7B sizes run locally on a single consumer GPU.
