arXiv:2605.17609v2 Announce Type: replace Abstract: Many inference-time language-model pipelines combine a cheap reward signal with an expensive verifier, such as exact answer checking in mathematical reasoning or hidden-test execution in code generation. We formalize this setting using a learning-theoretic lens as generative active search: a cost-sensitive first-positive search problem in which a policy adaptively samples candidates from an unknown distribution, observes cheap scores, and pays for verifier labels until it finds a positive example. For a fixed prompt, the generator and reward
This paper addresses a critical challenge in current large language model application development: optimizing the balance between computationally expensive verification steps and cheaper reward signals, which is increasingly relevant as LLM use cases expand.
A strategic reader should care because improving the efficiency of generative AI systems through adaptive search and cost-sensitive verification directly impacts computational costs, deployment scalability, and the reliability of AI-driven solutions.
This research provides a formalized framework for optimizing generative active search, potentially leading to more efficient and robust inference-time pipelines for complex AI tasks like mathematical reasoning and code generation.
