ARC-AGI-1 is a benchmark for fluid intelligence and abstract reasoning. Each task provides three or four input–output grid examples, followed by a new input whose output must be constructed. The task-specific rule is intended to be discovered on the fly rather than recalled from training. section 19.3.4
A typical ARC-AGI task
Study several paired grids, infer the transformation connecting each input to its output, then apply that transformation to an unseen grid. You receive three attempts before moving to the next task, so success depends on identifying the underlying logic rather than memorizing a familiar strategy. section 19.3.4
ARC-AGI controls for prior knowledge through core knowledge priors and tests only tasks that were not previously seen. Its resistance to memorization makes it a demanding test of generalization and on-the-fly recombination; scaling language models alone produced only limited progress on the 2019 benchmark. section 19.3.4 section 19.3.5
Figure 19.9 An ARC-AGI task: the nature of the task is demonstrated by a couple of input–output pair examples. Provided with a new input, you must construct the corresponding output.
Use the task figure to inspect how paired grids demonstrate a rule before a new grid must be solved. section 19.3.4
