Methodology
We use a SingleStep harness that searches prompts directly with default settings. We pass the query and 10 search results to GPT-5 mini, with GPT-4o-mini grading the output for correctness.
A dataset released by Google designed to test Retrieval-Augmented Generation (RAG) applications on factuality, retrieval accuracy, and reasoning.
Tip-of-the-Tongue
A benchmark for evaluating search engines on queries where users remember partial information about what they're looking for.
Evaluates web search systems specifically against conflicting, noisy, and ambiguous information.
A factuality benchmark released by OpenAI that measures the ability for language models to answer short, fact-seeking questions.
