OLMo
OLMo is Ai2's fully open language model, released in February 2024 in 1B and 7B sizes. Unlike most open-weight releases it published the entire pipeline: weights, the 3-trillion-token Dolma training corpus, training and inference code, intermediate checkpoints and evaluation suite, all under Apache 2.0, so the model can be reproduced and studied end to end as well as run locally.
