Mathematician Tristan Buckmaster publicly questioned whether OpenAI's landmark Millennium Prize problem solution was influenced by his user data from the past two months. OpenAI says it's "categorically impossible."

Buckmaster's response: "I just don't believe them."

The exchange has sparked debate, with some defending OpenAI and others treating it as a data-contamination red flag—highlighting how hard it is for labs to prove their results are isolated from user data.
