Meta's AI helped mathematicians answer five math questions that had no known answer
Mathematicians used Muse Spark in the regular meta.ai chat. Six papers came out, and each one marks which parts the AI wrote.

Meta makes an AI model called Muse Spark. On Friday, the company shared six math research papers. Mathematicians wrote them while working with the AI. Meta says five of them answer open questions. That means nobody had a known answer yet.
This is harder than a test. A test question already has an answer. In Meta's words, "There is no answer key" for open questions. You try ideas, make mistakes and often start over.
The mathematicians used the regular meta.ai chat, the same one anyone can open. They led the work. The AI helped them try ideas and build the steps of each proof. A second group of mathematicians then checked the work. Each paper marks which parts people wrote and which parts the AI wrote.
One paper is about a wave that keeps squeezing inward, in a model inspired by laser physics. The question was whether the wave must collapse. The paper shows that it must. That settles a question left open in 2015.
In another paper, the AI came up with a small example that breaks a test other mathematicians had proposed. The team then wrote a better rule.
Meta also says teams outside the company solved some of the same problems on their own, with different methods. The papers give them credit.
Why does it matter? AI has done well on contest problems that already have answers. Here it helped on questions where nobody knew the answer yet, with people guiding and checking every step.
Open it and check the claim yourself. That is the point.
