In December 2024, Fields medalists Terence Tao, Timothy Gowers, and Richard Borcherds described FrontierMath Tier 3 as "exceptionally challenging." Tao specifically predicted that this tier would "resist AIs for several years." However, the provided source indicates that these mathematicians were "fully saturated" with the challenge less than two years later, suggesting a quicker resolution than initially anticipated.
