Schema Harness Achieves 99% on ARC-AGI-3 Public Set Using Claude Opus 4.8 and Fable 5
Schema, a novel harness, achieves 99% performance on ARC-AGI-3 by enabling frontier models to simulate physics-inspired reasoning through joint state grounding and mechanism discovery. It improves model utility without altering weights, using executable programs for hypothesis testing and iterative model revision.
