Ai2 releases OlmoEarth v1.3 satellite embedding model with global precomputed embeddings and a browser explorer

Ai2 released OlmoEarth v1.3, a satellite embedding model that turns a year of Sentinel-1, Sentinel-2 and Landsat time series into one 128-dimensional vector per 10-meter pixel, with the first 64 dimensions usable as a smaller embedding. Ai2 precomputed annual embeddings for the whole planet and published them on Source Cooperative, and its 128-dimensional embeddings scored highest on 20 of 27 evaluations against AlphaEarth Foundations and Tessera v2, including a new tropical crop benchmark called PLANTEUR. The release also includes the OlmoEarth Embeddings Explorer, a no-sign-in browser tool for comparing years, finding similar places and training small classifiers on the spot, with 2025, 2024 and 2023 global and 2017 to 2022 covering select countries; weights, pretraining data and code are open.
