DataPrep-Bench: Benchmarking LLMs as Training Data Preparators

Read the original on arXiv Machine Learning →

arXiv:2607. 20465v1 Announce Type: new Abstract: The quality of training data fundamentally determines the capabilities of large language models (LLMs), yet no unified benchmark exists to measure how well LLMs, agents, and data-centric workflows actually prepare training data end to end.
