| Challenge: | Large language models exhibit systematic limitations in counting tasks due to depth constraints. |
| Approach: | They propose a method that decomposes large counting tasks into smaller, independent sub-problems that the model can reliably solve. |
| Outcome: | The proposed method surpasses architectural limitations and achieves higher accuracy on large-scale counting tasks. |
