When is a better LLM worth paying for? Stochastic Optimization with Switching Mixed-Fidelity Oracles

Large language models (LLMs) are increasingly used upstream of decision-making to clean data, detect label errors, and reconstruct missing values. Yet LLM-assisted data curation creates a new operational tradeoff: higher-fidelity models and richer prompts can be substantially more expensive, while the value of this add...
