What does OLMo 3 do?
Fully open data, weights, and training code.
The short answer
OLMo 3 is built by Allen Institute for AI and is positioned for research, writing and analysis. Our readings score it strongest on response speed and long-form writing.
Its weakest measured axis is code generation (74/100), so plan around that when the work depends on it. Access is open, and the weights are published, so the model can be inspected and self-hosted.

Energy, carbon and water
Carbon footprint reads 86/100. Serving runs largely on low-carbon power, with credible reporting behind it.
Water and local impact reads 84/100. Cooling relies on closed-loop or air-side designs with limited draw on stressed watersheds.
Speed and efficiency also matter here: a 82/100 speed reading means fewer compute-seconds per answer for routine work.
