Open Language Models (OLMos) and the LLM landscape (via) OLMo is a newly released LLM from the Allen Institute for AI (AI2) currently available in 7b and 1b parameters (OLMo-65b is on the way) and trained on a fully openly published dataset called Dolma.

The model and code are Apache 2, while the data is under the “AI2 ImpACT license”.

From the benchmark scores shared here by Nathan Lambert it looks like this may be the highest performing model currently available that was built using a fully documented training set.

What’s in Dolma? It’s mainly Common Crawl, Wikipedia, Project Gutenberg and the Stack.
