Mike Knoop says ARC-AGI-3 faces the same benchmark problem

ARC-AGI-3 faces the same pattern as an earlier problem, according to a post by Mike Knoop on X, dated October 11, 2026.

Knoop's post is quoted in a report that also includes a post by Domingos, which says a model has "swallowed the harness" and links an arXiv paper.

The report gives no details of the result. It does not say what the pattern is, which model is involved, or what the benchmark scores show.
