Ai2 ships open satellite embedding model OlmoEarth v1.3 with free global map explorer

Ai2 has published OlmoEarth v1.3, an embedding model that condenses a full year of radar and multispectral satellite data into a single compact vector for every 10-meter patch of the planet. Alongside it comes a free browser tool, the OlmoEarth Embeddings Explorer, that lets anyone compare landscapes across years or train tiny classifiers without touching a GPU. Benchmarked against AlphaEarth Foundations and Tessera v2 across 27 tests, the new model comes out on top overall while costing far less to train than its predecessors.
