# Endgame Simulations > The decision-rehearsal platform. AI agents with roles, goals and > constraints rehearse a high-stakes situation N times; the deliverable is > a distribution over outcomes with stated method, stated N, stated model > stack and stated world-date. Frequencies are k-of-N rehearsal outcomes > under stated assumptions — exploration of plausible dynamics, NOT > forecasts of real-world events.
