GPT-5.6 reportedly disproves 30-year-old statistics conjecture

A University of Pennsylvania statistics professor used OpenAI's GPT-5.6 Sol Pro to disprove a long-standing open conjecture about the Benjamini-Hochberg multiple-testing method in about 90 minutes. The predecessor model, GPT-5.5, failed to find a solution even after 20 hours of use.

Why it matters: It's a concrete data point in the debate over whether AI can produce genuinely new research results.
