Understand this story
On October 22, 2026, Ai2 released the satellite embedding model OlmoEarth v1.3, which generates 128-dimensional vectors for every 10-meter pixel worldwide, with the first 64 dimensions usable on their own, and it has publicly released the model weights, pretraining data, and code. According to Ai2, in 27 evaluations covering six continents, the 128-dimensional version scored highest on 20 of them and the 64-dimensional version led on 18, compared against AlphaEarth Foundations and Tessera v2. At the same time, it launched the login-free OlmoEarth Embeddings Explorer, which lets users browse global embeddings by year, find similar locations, and train small classifiers on the spot using a few labeled points; data for 2025, 2024, and 2023 has global coverage, while 2017 to 2022 covers only some countries. Other reports state that the model is a 128-million-parameter ViT-Base foundation model that processes time series of Sentinel-1, Sentinel-2, and Landsat imagery, and that it also introduced PLANTEUR, a benchmark for crop types in tropical farmland.

Ai2 Releases OlmoEarth v1.3, Offering Global 10-Meter Resolution Satellite Embeddings
The Allen Institute for AI released OlmoEarth v1.3 on October 22, 2026, including the OlmoEarth v1.3 Base model, 128-dimensional and 64-dimensional global precomputed annual embeddings, the login-free browser-based OlmoEarth Embeddings Explorer, and a technical report, all under the OlmoEarth Artifact License. The model is a 128-million-parameter ViT-Base foundation model that processes Sentinel-1, Sentinel-2, and Landsat image time series, outputting a 128-dimensional vector for every 10-meter pixel worldwide. Ai2 states that across 27 evaluations covering six continents, the 128-dimensional embeddings scored highest on 20 of them, while the 64-dimensional version led on 18; it also introduced PLANTEUR, a benchmark for crop types in tropical farmland, where the 128-dimensional embeddings achieved 24.9 mIoU in the benchmark's leave-one-island-out test, higher than Tessera v2's 19.1 and AlphaEarth Foundations' 15.8.
