Peter Diamandis posted on X that Elon Musk once predicted 100x gains in AI intelligence at fixed model size. Diamandis described the claim as once barely plausible but now established as fact. He added that current progress shows the performance ceiling remains far off. The post presents this assessment as confirmation drawn from ongoing model results rather than new announcements. No independent corroboration or specific benchmarks appear in the visible source lines. The statement stands as Diamandis's own evaluation of recent developments in the field.
