## Summary

AI2 releases OlmoEarth v1.3, a satellite embedding model that produces 128-dimensional vectors for every 10-meter pixel on Earth. Its embeddings score highest on 20 of 27 evaluations against AlphaEarth Foundations and Tessera v2, and its precomputed global embeddings are shared on Source Cooperative. The model weights, pretraining data and code are open under the OlmoEarth Artifact License, and the Explorer lets users compare years and train classifiers without an account.

## Why it matters

The source reports a 27-evaluation comparison and a $2,720 pretraining cost estimate, showing how a satellite embedding model performs against rivals and what it costs to reproduce.
