Benefiting from TESS and extensive ground-based follow-up efforts, we have obtained a sample of exoplanets with well-characterized masses and orbital parameters. This dataset provides powerful yet intricate insights into planetary system formation and dynamical evolution. I will demonstrate the capabilities of simulation-based inference for understanding these observations by tracing the evolution of planetary systems through N-body simulations. This approach enables us to infer the initial conditions of planetary systems, particularly regarding planet mass and mutual separation. Our findings suggest that close-in giant planet systems may have initial configurations markedly different from those of our Solar System.
