Galeio is a company specializing in developing custom foundation models for science and industrial applications.

## 🛰️ Our Models

### The Nereus Family 🌊
Named after the ancient Greek god of the sea, our Nereus models are specialized in ocean observation.
The models were developed in collaboration with world-leading SAR experts from (Ifremer)[https://en.ifremer.fr/].

#### Current Models
- **nereus-sar-1**: Our flagship foundation model
  - Trained on 10 years of Sentinel-1 Wave Mode data
  - State-of-the-art performance on ocean analysis tasks
  - Available architectures:
    - ResNet50 (75.5% TenGeoP accuracy)
    - ViT-S/16 (78.6% TenGeoP accuracy) (on-demand)
    - ViT-S/8 (82.1% TenGeoP accuracy)  (on-demand)
    - ViT-B/8 (83.6% TenGeoP accuracy)  (on-demand)
  - Excels at:
    - Wind speed prediction (RMSE: 1.37 m/s | best model ViT-B/8)  
    - Wave height estimation (RMSE: 0.63 m | best model ViT-B/8)
    - Geophysical phenomena classification
    - Many others (benchmarks coming soon)

### Nereus Family
The Nereus model family is dedicated to ocean observation and analysis using SAR imagery.

- **nereus-sar-1**: Our first foundation model trained on Sentinel-1 Wave Mode data:
  - Specialized for ocean SAR imagery analysis
  - Trained using dynamic dataset pruning for optimal performance
  - Available in multiple architectures (ResNet50, ViT variants)
