Largest AI Training Runs
The biggest training run (in total floating-point operations) each AI lab has ever published or been credibly estimated to have completed. From AlexNet's two-GPU experiment in 2012 to the 100,000-GPU clusters of 2025, the record climbs eight orders of magnitude — a doubling of frontier compute roughly every six months.
