Sim racing: machine GT Sophy against human Top GT drivers
Sony AI’s GT Sophy beat four of the world’s top-ranked Gran Turismo drivers in a head-to-head competition on 21 October 2021, having lost the first exhibition three months earlier. The result holds inside the simulator, under the same cars, track and input limits. It is not a claim about real-world driving.

Conditions and comparability
Machine conditions
Four instances of the agent raced four top drivers across three races in Gran Turismo Sport. An earlier July 2021 event was won by the humans.
Why this is broadly comparable
Same game, same cars, same track, same controller-rate input limits — a fair contest inside the simulator. It is not a claim about real-world driving. Sophy lost the first exhibition in July 2021 before winning in October, which is the honest shape of the crossover.
Machine progression
4 recorded results. Overtaq keeps every published result rather than only the current best, so the frontier can be read as a history. This table is the full data behind the chart on the interactive record.
