| Challenge: | RFC-Bench evaluates large language models on financial misinformation under realistic news . current models struggle to maintain coherent belief states without external grounding, study finds . |
| Approach: | They propose a benchmark for evaluating large language models on financial misinformation under realistic news. |
| Outcome: | The proposed model performs better when context is available, while reference-free settings expose significant weaknesses. |

| Challenge: | Existing evaluations of LLMs in finance are text-only, monolingual, and largely saturated by current models. |
| Approach: | They propose a multilingual and multimodal benchmark for evaluating LLMs in real financial contexts. |
| Outcome: | The first expert-annotated multilingual and multimodal benchmark is released . it evaluates 21 leading LLMs and shows they perform better in multilingual settings . |

| Challenge: | Existing studies on sentential paraphrase detection focus on finer grained paraphrases, i.e., phrasal paraphrase. |
| Approach: | They propose to use the SPADE to evaluate syntactic phrase alignment in paraphrasal sentences. |
| Outcome: | The proposed method is compared with humans and provides benchmarks to show its performance. |
