| Challenge: | a systematic review of large language models (LLMs) is conducted to better align their capabilities with real-world demands. |
| Approach: | They propose a functional taxonomy mapping financial domains to tasks, datasets, and institutional constraints. they catalog over 30 financial benchmarks and 20 representative models. |
| Outcome: | The proposed model frameworks are bridging financial practice and LLM research. |
