Elon Musk has announced that Tesla’s new custom AI chip is about six months away from being installed in new production cars. The CEO said that the chip, which was confirmed as being in development last December, will offer “somewhere between [a] 500% & 2000%” increase in its vehicle’s autonomous driving performance. Existing Tesla owners who have already paid for full self-driving will be offered this “hardware 3” update for Autopilot free of charge.

The announcement comes as v9 of Tesla’s onboard software has already reportedly brought big improvements to its neural network with a unified camera network that more seamlessly integrates all eight of the car’s cameras. Musk has suggested that this software update delivered an approximate 400 percent increase in its capabilities.
