Clay Foundation Model

An open source AI model for Earth

Clay is a foundational model of Earth. It uses a Vision Transformer architecture adapted to understand geospatial and temporal relations on Earth Observation data. The model is trained via Self-supervised learning (SSL) using a Masked Autoencoder (MAE) method.

The Clay model can be used in three main ways:

• Generate semantic embeddings for any location and time.
• Fine-tune the model for downstream tasks such as classification, regression, and generative tasks.
• Use the model as a backbone for other models.
