benchmarks

Saturated and contaminated benchmarks separate models less than the noise in your own traffic. Use public scores to shortlist and a private, refreshed eval to decide.

The headline horizon is a 50% success rate on someone else's tasks. Plan on the 80% horizon for your own tasks, break long jobs into checkpoints and keep long-autonomy features as dated bets.

Leaderboards move every few weeks and every team feels the pull. The interviewer is checking whether you have a repeatable switching process or just enthusiasm.

The model stayed the same, some runs disappeared and the grader changed. Reconcile the report before deciding what the result supports.

Short-answer benchmarks say little about ten-page reports. Check each statement against the source it cites, score coverage against an expert outline, test balance on contested topics and measure whether users act without redoing the work.

Benchmarks die from leakage, label errors and saturation. Hold back a private split, audit labels with experts, score abstention, watch the public-private gap and publish when you will retire it.
