Exploring OlmoEarth v1.1: Revolutionizing Remote Sensing with Advanced AI Models
In the ever-evolving domain of remote sensing, the introduction of OlmoEarth v1.1 has substantially changed the landscape for organizations striving to monitor environmental changes rapidly and efficiently. Initially launched in November 2025, this platform has empowered a variety of applications, from tracking mangrove changes to producing national crop-type maps in a matter of days. With each iteration, OlmoEarth takes vital steps towards its mission: providing cutting-edge AI to support organizations preserving our planet.
The Cost of Efficiency in Remote Sensing
Running remote sensing models at scale can be quite demanding, especially regarding computational resources. The lifecycle of deploying OlmoEarth involves several stages, including data export, preprocessing, inference, and post-processing. Among these, the compute cost often stands out as the highest. A crucial element is efficiency, ultimately determining how many partners can utilize the platform effectively.
The Need for OlmoEarth v1.1
Recognizing this need, the developers introduced OlmoEarth v1.1, designed to cut compute costs by up to 3x while maintaining high performance on various research benchmarks. The emphasis on efficiency ensures that users across the board can implement this advanced technology without a significant financial burden.
Transforming Token Efficiency
At the heart of OlmoEarth are transformer-based models, which have become the go-to architecture in contemporary machine learning. But how does this translate when processing remote sensing data? The key to enhancing efficiency lies in token representation. The input data, such as Sentinel-2 imagery, is converted into sequences of tokens that the model can understand.
Controlling Compute Costs: Model Size and Token Sequence
Two main factors influence efficiency: model size and token sequence length. While the model size allows users to select an option that fits their computational budget, the token sequence length directly impacts compute costs. The quadratic scaling relationship of compute costs with token sequences means even minor reductions can result in significant cost savings when running the model.

Designing Effective Tokens
One of the fundamental questions in developing transformer-based models is: What should a token represent? In the case of Sentinel-2 imagery—which consists of a tensor with multiple dimensions—efficient token design is essential. For instance, when images are broken into smaller resolution-based patches, each patch generates a token for every resolution and time step.
Maximizing Token Efficiency
This technique mirrors practices seen in models like Galileo and SatMAE, which further enhance the understanding and processing of remote sensing data. While typical methods may focus on a singular token per resolution, OlmoEarth adopts a multi-token approach to maintain high performance without inflating compute costs. Conversely, using a single token for all bands reduces the total count of tokens by threefold, thus conserving resources throughout pretraining and inference.
Enhancing Model Performance
To merge tokens without sacrificing performance, OlmoEarth v1.1 necessitated adjustments to the pre-training regimen. These changes are detailed in the technical paper accompanying the model, aiming to empower researchers and developers to comprehend the underlying mechanics more thoroughly.
For Developers: Unlocking Cost-Effective Solutions
Developers will find that OlmoEarth v1.1 operates up to three times more affordably than its predecessor while retaining a high level of performance similar to OlmoEarth v1. If users leverage models from the original family, transitioning to v1.1 offers significant speed benefits during fine-tuning and inference without a massive trade-off in accuracy.
For Researchers: Unpacking the Model Layers
Pre-trained remote sensing models come with numerous variables, making performance evaluation complex. With OlmoEarth v1.1 trained on the same dataset as its predecessor, researchers can isolate and understand the effects of new methodological changes more effectively. This investigation into model performance can pave the way for deeper insights into preparing pre-trained models for various remote sensing applications.
Get Started with OlmoEarth v1.1
For those interested in making use of these transformative capabilities, OlmoEarth v1.1 combines both Base, Tiny, and Nano models, along with their respective weights and training code. This accessibility further accelerates the deployment of planet-scale map refreshes, reinforcing OlmoEarth’s commitment to making advanced machine learning more attainable and cost-effective for all users.
As OlmoEarth continues to evolve, its innovations promise to enhance our capability to protect and understand our planet—a goal vital in today’s rapidly changing environment. Each step in its development reinforces the central motto: leveraging technology to foster and sustain ecological resilience.
