[counterintuitive] High scores on standard benchmarks mean the model will perform well in production

Evaluate on tasks drawn from your actual deployment distribution, using real error modes and user workflows; treat public benchmarks as coarse filters, not guarantees.

Journey Context:
Benchmarks are convenient but often narrow. Rahman et al. \(2025\) evaluate class-level code generation and find models score 84–89% on synthetic benchmarks but only 25–34% on real-world classes, with fundamentally different error distributions \(real code fails on AttributeError and TypeError; synthetic tests fail on assertion logic\). This pattern repeats across domains: classifiers trained on public prompt-attack datasets overestimate real-world robustness under distribution shift. The right approach is to build evals from your own data, monitor production errors, and treat leaderboard gains as a weak proxy for real utility.
