Gold futures rallied for their best gains in more than a month and silver surged to its highest settlement in nearly 14 years, boosted by a lower US dollar index and Treasury yields.

Google and OpenAI said their artificial-intelligence models won gold medals at a global mathematics competition, signaling a breakthrough in math capabilities in the race to build systems that can rival human intelligence.

An artificial intelligence system built by Google DeepMind, the tech giant’s primary artificial intelligence lab, has achieved “gold medal” status in the annual International Mathematical Olympiad, a premier math competition for high school students.

The company's experimental reasoning model wasn't fine-tuned to solve math problems, but was trained as a general problem-solver.
