Benchmark Contamination Explained, and What to Do About It
Contamination inflates scores when test data leaks into training. How it happens, why it is over-diagnosed, and the practical defences that actually work.
ReadPractical writing for developers building with large language models — how they work, how to pick one, and how to keep the bill predictable.
Contamination inflates scores when test data leaks into training. How it happens, why it is over-diagnosed, and the practical defences that actually work.
ReadAn agent that is 95 percent reliable per step fails most thirty-step tasks. Why compounding error, not peak capability, decides which model to run in a loop.
ReadBackend work is the one domain where SWE-bench scores roughly mean what you want them to mean — and the places where they still mislead you.
ReadWhen nobody is waiting for the answer, latency stops mattering and unit cost dominates. How to pick and operate a model for offline high-volume work.
ReadThe code runs, the chart renders, and the conclusion is unsound. Why data science needs a different evaluation than general code generation.
ReadInfrastructure code fails differently: rarely, and expensively. Why terminal benchmarks are the relevant signal and what to gate before applying.
ReadDocumentation is the task where fluent output is most dangerous, because readers cannot verify it. How to pick and constrain a model for docs that stay true.
ReadAt enterprise scale the constraints are licensing, data residency, auditability and version stability. How those narrow the field before capability matters.
ReadFrontend work has no oracle that tells you the output is wrong. What that means for model choice, and how to close the loop with screenshots.
ReadGo is the language models write most confidently, and confidence is the problem. Where generated Go compiles cleanly and still races under load.
ReadA million-token window does not make a model good at a million-line codebase. What actually determines whether a model can work in a large repository.
ReadLegacy work is mostly reading, not writing. Why the model that scores highest on code generation is often the wrong one for a twenty-year-old codebase.
