custom silicon chip

Rivian’s first “Autonomy and AI Day” unveiled a custom silicon chip, proprietary vehicle computer, and new AI models to enable Level 4 self‑driving on its upcoming R2 platform, using lidar, radar and cameras. The company introduced an Autonomy+ subscription—$2,500 one‑time or $49.99 per month—significantly cheaper than Tesla’s FSD. A “Universal Hands‑Free” feature will allow hands‑free driving on 3.5 million U.S. miles, and an AI‑powered “Rivian Assistant” voice interface is slated for 2026. A $5.8 billion JV with Volkswagen supports the rollout, though shares fell 6.1% amid market volatility.
