Title: Zero-Shot Confidence Estimation for Small LLMs: When Supervised Baselines Aren't Worth Training
Abstract:
arXiv:2605.02241v2 Announce Type: new Abstract: How reliably can a small language model estimate its own correctness? The answer determines whether local-to-cloud routing-escalating queries a cheap local model cannot handle-can work without supervised training data. As inference costs dominate large language model (LLM) deployment budgets, routing most queries to a cheap local model while reserving expensive cloud calls for hard cases is an increasingly common cost-control strategy.
