The model partially solves the problem but fails to learn the correct loop length:
> An investigation of model errors (Section 5) reveals that, whereas large language models commonly “hallucinate” random solutions, our models fail in principled ways. In almost all cases, the models perform the correct calculations for the long Collatz step, but use the wrong loop lengths, by setting them to the longest loop lengths they have learned so far.

The article is saying the model struggles to learn a particular integer function. https://en.wikipedia.org/wiki/Collatz_conjecture
