OlmoEarth v1.3
Ai2's open Earth-observation model with precomputed 10 m global embeddings and a no-login Embeddings Explorer.
Overview
Ai2 published OlmoEarth v1.3 on October 22, 2026. It turns a year of Sentinel-1 radar, Sentinel-2 and Landsat imagery into embeddings, which Ai2 precomputed for the whole planet at 10 m resolution in 64- and 128-dimension versions. Across 27 evaluations the 128-dimension embeddings scored highest on 20 and the 64-dimension version on 18 against AlphaEarth Foundations and Tessera v2, per Ai2. Training used about 53% of v1.2's compute, and Ai2 estimates reproducing the Base pretraining run would cost about $2,720 in rented H100 time. Weights, pretraining data, and code are open under the OlmoEarth Artifact License.
