Public name for xAI's large training cluster. Counts in posts go stale fast.

A discussed wafer fab large enough to feed the chip habit. Not a plant address on this desk.

Tesla's purpose-built robotaxi concept. The workbook price is a placeholder, not a sticker.

Miles with no paying rider. The empty trip to the pickup, and the trip home to the depot.

The polygon where a service is allowed to drive. Outside it, the car is a car.
