According to the post, this result was first derived for gluons in a previous paper. That paper was provided to the model as context, and then the model was asked to derive an analogous result for gravitons, which presumably has not been done before. The authors claim it would have taken "considerable time" for human experts to derive the graviton result.

I don't see any reason to believe that this exact problem was solved before in the training data, but it's definitely an incremental result based on a very similar problem that the model had seen before.
