The TABLET benchmark evaluates how well large language models perform prediction tasks on tabular data, especially tables combining textual and numerical inputs. section 1.5
LLMs versus XGBoost
Using four-shot examples, ChatGPT averaged an F1 score of 0.68 and Flan-T5 11b averaged 0.66. XGBoost, trained on the entire dataset, averaged 0.94. section 1.5
The benchmark highlights three practical conclusions:
- Fully supervised tabular models can substantially outperform prompted LLMs on prediction tasks. section 1.5
- LLMs remain stronger at instruction following and producing textual outputs than at extracting additional predictive information from tabular data. section 1.5
- Operational concerns include GPU cost, scalability, latency, and throughput. section 1.5
