Microsoft Research uses AI collaboration to prove the 31-year-old KLS conjecture
Microsoft Research's Xinzhi Zhang and Zhao Song proved the KLS conjecture, first proposed in 1995, through human-guided AI collaboration — the day's most important breakthrough. On the security front, OpenAI and Google Wiz discovered two critical PHP vulnerabilities hidden for over 20 years, affecting roughly 70% of websites. Additionally, OpenAI models announced their arrival on Google Cloud, and NVIDIA made intensive releases of local AI hardware along with several open-source and relational foundation models.

Solving a 31-year-old grand challenge in mathematics – the KLS conjecture
Microsoft Research's Xinzhi Zhang and Zhao Song have proved the Kannan-Lovász-Simonovits (KLS) conjecture, proposed in 1995, showing that for log-concave distributions the difference between the flattest hyperplane cut and the optimal cut of any shape is bounded by a universal constant independent of dimension.
