Outline
InfGen is an integrated model for long-term driving simulation of autonomous driving systems. Existing models focus on short-term, closed-loop motion simulations and are unsuitable for long-term simulations. InfGen is a next-generation token prediction model that performs closed-loop motion simulation and scene generation in parallel, automatically switching between the two modes to enable stable long-term simulations. It demonstrated state-of-the-art performance in short-term simulations of 9 seconds and significantly outperformed existing methods in long-term simulations of 30 seconds. The code and model will be released at https://orangesodahub.github.io/InfGen .
