Harnesses + smart models = the end of the last famous hard benchmarks. Models can now work for extremely long times (bye, METR Long Tasks), they can output professional documents with correct math (so long, GDPval) and they can solve complex novel puzzles (farewell, ARC-AGI-3). Gemini 4 Argon from @Google on ARC-AGI (Verified): - ARC-AGI-3: 97.5%, 4.8K (provider adapter harness), 49.8%, 5.8K (standard harness) - ARC-AGI-2: 91.3%, 0.32/task - ARC-AGI-1: 98.5%, 0.16/task Google DeepMind is the second frontier AI lab to score above 95% on ARC-AGI-3.
