I know next to nothing about deepseek, but it does seem unusual that their scores are so close to o1. What are the chances they happened to be almost exactly on

I know next to nothing about deepseek, but it does seem unusual that their scores are so close to o1. What are the chances they happened to be almost exactly on par with the state of the art? That being said it’s a great model at an amazing price point (I’ve been using it exclusively), but IMO they probably leveraged existing models’ outputs in training.
