Google's RT-2 packed 55B parameters, 1000x RT-1's 55M just 7 months later

Timothy B. Lee points out a striking fact: Google's first transformer-based robotics model, RT-1, had 55 million parameters—while RT-2, released just seven months later, had 55 billion. That's a 1000x leap in seven months, a vivid illustration of how fast robotics foundation models scaled.
