OLMo 2 7B
Truly open 7B: weights, code, data, and checkpoints all public.
About
Allen AI's second-generation open language model and one of the few that meets the Open Source Initiative's definition of open source AI — training data, code, recipes, evaluations, and intermediate checkpoints are all public.
Trained on 5 trillion tokens. A research artifact first and foremost: the value is being able to study exactly how it was built, not just use the weights.

Benchmarks
Competitive with similarly-sized open models including Meta's Llama per Ai2's report; positioned as a research baseline rather than a leaderboard entry.
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
Use cases
Trust score — 8/10
Scored 8/10 (verified tier, metrics-v1). Evidence: Reference model for open-science LLM research; widely used in academic work; Superseded by newer OLMo generations but checkpoints and recipe remain maintained; Meets the OSI open source AI definition: data, code, checkpoints, and evals all public. Manual review: release facts verified against Ai2's announcement and TechCrunch coverage. License: Apache 2.0.
