| Challenge: | Existing TTC scaling strategies and reasoning scorers are fragmented and evaluated under inconsistent protocols. |
| Approach: | They propose a framework for seamless test-time compute scaling of large language model reasoning . they use a modular Python library to implement state-of-the-art scaling strategy and scorer families . |
| Outcome: | The proposed framework evaluates performance and computational efficiency on mathematical and coding tasks. |

| Challenge: | Uncertainty quantification (UQ) is a framework for assessing the reliability of model outputs. |
| Approach: | They introduce pre-trained UQ heads for LLMs that are highly robust and generalized to languages they were not explicitly trained on. |
| Outcome: | The pre-trained heads significantly improve their ability to capture uncertainty compared to unsupervised methods. |
