The speaker explains why benchmaxing — training models to game benchmarks rather than improve real-world performance — persists despite industry insiders acknowledging the problem. Key anti-patterns in benchmark creation are detailed: prohibitive cost leading to quality shortcuts, contamination as a default outcome (with evidence that Claude Opus has memorized SWE-bench Verified), reward hacking via lazy verifier exploitation, and lack of product sense in task design. Labs can further game results by hiring crowdsourced voters, using non-representative eval conditions, or testing models without disclosure. The proposed solution involves expert-driven benchmark design, high-fidelity real-world data, robust verifiers, private holdout sets, and human evaluation — illustrated by Surge AI's Hemingway Bench, which uses professional writers for blind model comparisons. ## Full article daily.dev links to this article rather than hosting it.
