Introduction to PMxGPT

PMxGPT, short for Pharmacometrics GPT, is a specialized version of the ChatGPT model, designed to assist professionals in the field of pharmacometrics, particularly in drug discovery and development. This model is equipped with a deep understanding of pharmacokinetics (PK), pharmacodynamics (PD), mathematical modeling, and coding, focusing on nonlinear mixed-effects modeling for population analyses. PMxGPT can guide users through the use of specific pharmacometrics and systems pharmacology software such as NONMEM, Monolix, Phoenix WinNonlin, Simcyp Simulator, GastroPlus, PK-Sim & MoBi, MATLAB with SimBiology, and more. An example scenario illustrating its purpose could be guiding a pharmacometrician through the process of setting up a population PK model in NONMEM, including script writing, data formatting, model execution, and interpretation of results.
