Model Card

OLMo 3 7B Think is an efficient reasoning model from the Allen Institute for AI (AI2), purpose-built for multi-step problem solving in math, coding, and general analytical tasks.

Trained using a thinking SFT, thinking DPO, and RLVR pipeline, it generates structured chain-of-thought reasoning traces. On math benchmarks it matches Qwen 3 8B on MATH and comes within a few points on AIME 2024 and 2025. On coding, it leads similarly-sized models on HumanEvalPlus.

Fully open under a permissive license, it is the most capable fully open reasoning option at the 7B scale — ideal for API use cases requiring strong reasoning at a small model footprint.
