And that's a problem. Figuring it out is one of the biggest scientific puzzles of our time and a crucial step towards controlling more powerful future models.Sarah Rogers/MITTR | Getty Two years ago, Yuri Burda and Harri Edwards, researchers at the San Francisco–based firm OpenAI, were trying to find out what it would take to get a large language model to do basic arithmetic. They wanted to know how many examples of adding up two numbers the model needed to see before it was able to add up any t...
