TEOChat is a groundbreaking vision-language AI system that can analyze and discuss temporal sequences of satellite imagery, enabling time-based earth observation analysis previously impossible with standard LLMs.

• Processes multiple satellite images over time to detect changes and patterns
• Excels at critical applications like building damage assessment and land use monitoring
• Trained on a specialized instruction dataset for temporal earth observation tasks
• Outperforms existing models in understanding complex temporal patterns in satellite data

For security applications, TEOChat enables rapid damage assessment following disasters, infrastructure monitoring, and detection of suspicious changes in sensitive areas—capabilities essential for modern security operations.
