MET if The panel of judges mutually agreed by Gary Marcus and Miles Brundage determines that AI systems existed by the end of 2027 that can perform at least 8 of the 10 tasks listed in the 30 December 2024 post (movie comprehension, novel comprehension, biographies/obituaries, video-game mastery, legal briefs, 10,000+ line bug-free code, Pulitzer-caliber books, Oscar-caliber screenplays, Nobel-caliber discoveries, formalization of math proofs), where tasks need not have been actually attempted commercially but must be technically feasible with modest per-task cost (roughly $1 million of compute plus 10 person-weeks), and where the tasks are not performed by 10 completely separate bespoke systems. at any point, before 2027-12-31 23:59 (UTC).

The original wording did not settle the timing on its own. The reading above was chosen at registration and locked with the claim — it was not decided after the fact.

◎ The test — locked before the outcome was known

Settled by the determination of the mutually agreed panel of judges described in the post: if the panel finds that AI systems capable of performing at least 8 of the 10 listed tasks existed (or were technically feasible at ~$1M compute + 10 person-weeks per task) by 31 December 2027, the claim resolves true; if the panel finds fewer than 8 tasks met, it resolves false. Judges may take months after the deadline to render the decision.

Thonest does not settle this one automatically — there is no supported data source for it. The test is fixed all the same, so anyone can check it and nobody can change what counts.
