OlmoEarth v1.1: A more efficient family of OlmoEarth models

arXiv:2605.20804v1 Announce Type: cross Abstract: We present a set of improvements to the OlmoEarth family. These improvements allow us to cut compute costs during training ($1.7 \times$ reduction in GPU hours required to train our Base models) and inference ($2.9\times$ reductions in MACs on Sentinel-2 tasks), while maintaining the models' overall performance. All training code is available at github.com/allenai/olmoearth_pretrain.

Why this matters
Why now

The continuous drive for efficiency in large AI models is pushing developers to find innovative ways to reduce computational overhead for both training and inference. This release reflects the ongoing, rapid iteration seen in AI model development.

Why it’s important

Efficiency improvements in AI models directly translate to lower operational costs, broader accessibility, and potentially faster deployment of advanced capabilities across various applications, including environmental monitoring and defense.

What changes

The cost barrier for developing and deploying high-performance AI models like OlmoEarth is being incrementally reduced, making sophisticated AI more attainable for projects with budget constraints.

Winners
  • · AI developers
  • · Cloud providers (reduced resource consumption for same performance)
  • · Environmental monitoring agencies
  • · Defense sector (for intelligence gathering)
Losers
  • · Less efficient AI research groups
  • · Companies with high compute burn rates
Second-order effects
Direct

Further acceleration of AI deployment in various sectors due to lower cost and improved performance-per-watt.

Second

Increased pressure on hardware manufacturers to deliver even more efficient processing units to keep pace with software optimization.

Third

Enhanced global access to sophisticated AI capabilities as costs become more manageable for a wider range of organizations and nations.
