The Noble Element Simulation Technique (NEST) is a C++ package with optional GEANT4 integration and a Python equivalent (nestpy) that accurately simulates the scintillation, ionization, and electroluminescence processes in xenon and argon. Using a combination of empirical and first principle methods, NEST models the intrinsic physics of noble detectors while maintaining a format that is accessible and customizable for users. I will present key results including energy resolution and light and charge yields of various interactions with noble elements. I will also discuss recent and future updates to the code including further development of the argon model, improvements to the ER model, and new modeling to describe the W-value discrepancy between NEST and the EXO-200 results.
