OlmoEarth v1.3 opens planet-scale satellite embeddings

Ai2 released OlmoEarth v1.3, an open satellite foundation model that compresses annual Sentinel-1, Sentinel-2, and Landsat imagery into 128-dimensional embeddings for each 10-meter land pixel. Precomputed global data and a no-login browser explorer make crop mapping, land-cover analysis, and change detection far more accessible.

// ANALYSIS

OlmoEarth v1.3 turns expensive geospatial modeling into a lightweight feature-engineering problem, making serious Earth-observation AI practical for smaller teams.

–Precomputed embeddings eliminate the need to download massive imagery archives or run the foundation model locally.
–Ai2 reports top performance on 20 of 27 evaluations against AlphaEarth Foundations and Tessera v2.
–The 64-dimensional variant offers a cheaper path for large-scale classifiers and similarity searches.
–Open weights, data, code, provenance, and browser tooling create a strong foundation for reproducible AI-for-science workflows.
–The main limitation is that downstream users still need labeled data and geospatial expertise to build reliable task-specific maps.

System One Models Challenge LLM Legal Certainty

A new arXiv study tests four System One decision models against six generative LLMs on legal-authority verification, including 1,670 cases where the correct holding is missing. The best decision model matched the top LLM’s 88.1% standard-task accuracy at roughly 1/55 the cost, while combining both approaches reduced wrong citations.
