Plays the chart through its history. Pauses are where the data set a record or moved most.
Epoch AI (CC BY 4.0). A model counts for a country when one of its developers is based there. Above zero, the best U.S. model scores higher. The gap jumps when either side releases a new best model. Palanor calculation.
The U.S. lead at the frontier, in one line. It narrows when a Chinese lab releases a model close to the U.S. best and widens when a U.S. lab moves the frontier again.
