In <a href="https://openai.com/index/navier-stokes-solution/">a blog post on Tuesday</a>, OpenAI announced that it discovered a solution to the Navier-Stokes problem - which relates to the flow of liquid and gas - using an internal AI model more powerful than the newly released GPT-6 Astra alongside 10,000 concurrent agents. The Navier-Stokes problem is one of seven <a href="https://www.claymath.org/millennium-problems/">Millennium Prize Problems</a>, each of which comes with a $1 million reward for solving. </p> <p class="wp-block-paragraph">OpenAI says it started training the internal AI model on August 28th, which has "exhibited unpreced …</p> <p><a href="https://www.theverge.com/ai-artificial-intelligence/991710/openai-navier-stokes-solution">Read the full story at The Verge.</a></p>
