| Challenge: | Existing benchmarks designed to evaluate the reasoning capabilities of large models are limited in scope and lack flexibility to adapt difficulty according to evolving reasoning capacities of models. |
| Approach: | They propose a benchmark that incorporates multidisciplinary questions to evaluate the reasoning capabilities of large models and can adjust and update question difficulty based on the reasoning abilities of advanced models. |
| Outcome: | The proposed benchmark incorporates multidisciplinary questions to evaluate the reasoning capabilities of large models and can adjust and update question difficulty based on the reasoning abilities of advanced models. |

| Challenge: | Existing models that process multiple modalities of data have been used for multimodal tasks, but their advanced capabilities raise privacy concerns. |
| Approach: | They propose a method to modify the model’s internal states associated with PII-related content and to reduce the risk of PI I leakage by modifying the model's internal state. |
| Outcome: | The proposed method achieves on average 93.3% refusal rate for various PII-related tasks with minimal impact on unrelated model performances. |
