AI researchers automatically build challenging benchmarks by searching the internet

Researchers have developed an automated framework to construct challenging benchmarks by searching the internet. This method models the internet as a topic space and uses a multi-armed bandit approach to identify difficult topics through evaluation queries. The epsilon-greedy strategy significantly reduces the cost of benchmark creation by exploring only a small fraction of the potential search space, demonstrating effectiveness in machine translation and knowledge question answering.

    Searching the Internet for Challenging Benchmarks at Scale

    arXiv:2509.26619v2 Announce Type: replace Abstract: Many static benchmarks are beginning to saturate: as models rapidly improve, they achieve near-perfect scores on fixed test sets, leaving little headroom to expose genuine model weaknesses -- and even expert-curated challenge se…
