Claim

Greg Brockman declared welcome to the AGI era and called the framing not unreasonable, as Sam Altman said the lab is pacing its progress on safety and the model beat Pokémon in 18 hours, hit 99.9% on ARC-AGI-3, subsumed the harness entirely and set a record on the capabilities index.

Reported metric: 99.9% ARC-AGI-3 / ECI 169
