We present the Generation III Bern model. This model solves as directly as possible the underlying differential equations for the structure and evolution of the gas disc, the dynamical stateof the planetesimals, the internal structure of the planets yielding their gas accretion rate and internal structure, the accretion rate of planetesimals, disc-driven orbital migration, and the gravitational interaction of concurrently forming planets via a full N-body calculation. The model also follows the long-term evolution of the planets on Gigayear timescales after formation including the effects of cooling and contraction, atmospheric escape, bloating, and stellar tides. After a rapid presentation of the model, we will present some of the key first results of the model.
