AlpaSim

What it is

A research simulator for autonomous driving that runs driving policies in closed loop, rendering camera feeds from neural scene reconstructions or video models alongside vehicle dynamics and traffic. Components talk over gRPC as separate services, so researchers can swap in their own renderer, controller, or driver model and scale runs across nodes with Docker Compose or SLURM. AV researchers use it to validate algorithms, probe edge cases, benchmark models such as Alpamayo and VaVAM, and debug driving behavior.
