Researchers have developed a new method for optimizing generative AI engines by creating a scorer that predicts which pages will be cited in an answer. They evaluated various rerankers and decision models on the GEO-Bench dataset, finding that larger models and a fine-tuned Qwen3-Reranker-4B performed strongly. The study also demonstrated that a distilled 4B student model could achieve comparable results to larger models when trained on specific labels, suggesting efficient optimization strategies for AI answer engines. The team has released the model, benchmark, predictions, and code for public use. AI
IMPACT This research could lead to more efficient and accurate AI answer engines by improving how they select and cite relevant information.
