SysCaps introduces natural language interfaces for complex energy system simulations, making powerful surrogate models accessible to experts and non-experts alike.

• Creates text descriptions (system captions) that effectively interface with simulation surrogates
• Enables multimodal learning combining text and time series data
• Demonstrates effectiveness across multiple energy domains including buildings and wind farms
• Reduces barriers to using sophisticated engineering tools through intuitive language interaction

This innovation bridges the gap between advanced engineering models and practical accessibility, potentially accelerating adoption of simulation tools in energy system design and optimization.
