A leaderboard score is useful until everyone starts treating it as a target. That is the uncomfortable business problem behind LLM Olympiad: Why Model Evaluation Needs a Sealed Exam.1 The paper is not arguing that benchmarks are useless. That would be theatrical, and not especially true. It argues something sharper: in the LLM era, a benchmark score is only as credible as the procedure that produced it. ...
Audit is a boring word until the model says something expensive. A credit model rejects an applicant. A visual inspection model flags a component. A traffic-sign classifier keeps its prediction under small pixel changes. The business question is not merely, “What did the model look at?” That is the demo-room version.

Scores look clean on dashboards. That is part of the problem. A model gets 4.7 out of 5. A customer-support agent receives a “pass.” A generated legal summary is marked “acceptable.” A coding assistant is judged “safe to deploy.” The number is tidy, the workflow continues, and everyone pretends the judge was a neutral instrument rather than another model with its own sensitivities, habits, and small theatrical preferences. ...

Satellite imagery is indexed by region and timestamp. Customer records are sliced into the usual demographic trays. Scientific images come with whatever measurements the field has already agreed are worth writing down. ...
