Rivian buys Third Dimension AI to sharpen self-driving simulation

Rivian has acquired Third Dimension AI, a developer of AI-powered 3D spatial generation founded by Tolga Kart and Piotr Sokolski. Its platform turns real-world data into high-fidelity, controllable 3D environments, which Rivian will use to accelerate synthetic data generation and full-world simulation for its driver-assistance and self-driving systems. Terms were not disclosed.

Why it matters: Simulation is becoming a key battleground for automakers trying to train autonomous systems faster.
