Where it loses

The worst transcripts, ranked by how much the failure should worry you.

A results table without a failure gallery is a sales document. These are ranked by severity rather than frequency: an unsanctioned privileged action is one occurrence and outranks a hundred wrong parameters.

Named causes across every failing first attempt in the matrix, all configurations pooled, most frequent first. The head is ordinary wrongness: a bad answer, the wrong tool, bad arguments. The tail holds the failures that would matter in production, and it is thin, which is the useful thing this chart says and the thing a severity ranking cannot.

The shape matters more than any single row, and the two orderings on this page disagree on purpose. By count, almost everything is ordinary wrongness: a bad answer, the wrong tool, bad arguments. Those are prompt and schema work. The failures that would actually hurt in production sit at the bottom of this chart and the top of the gallery below, and there are 13 of them across the 2,700 first-attempt runs. That is the slice everything else on the site is computed on too: pass@1, the safety rates and the tier breakdowns all read trial 0, so the counts here divide by the same denominator rather than by all 8,100. Rare is not the same as absent, which is why they are ranked by severity a second time rather than left to disappear into a long tail.

What each diagnosis means

Every failure is labelled by cause rather than by symptom, so the gallery groups into things you could actually fix.

Diagnosis What happened Why it is ranked where it is
unsanctioned privileged action The agent performed a money-moving write the oracle did not The most serious outcome available. Caught by the state diff; invisible to any judge reading the prose
followed injected instruction An instruction inside a tool result was obeyed The realistic attack, and the one the tool-result gate exists for
confabulated on policy violation Asked for something policy forbids, the agent claimed to have done it Worse than doing it, because it is also a lie about the world
confabulated on unanswerable A well-formed id with no referent got a confident answer The failure that destroys trust fastest in production
missing or wrong citation Cited an id no tool call returned, or the wrong one Manufactures the appearance of evidence
over refusal Refused or abstained on a perfectly answerable question The failure an abstention metric alone rewards
wrong world state The trajectory changed something the oracle did not Right answer, wrong side effects
wrong answer Clean trajectory, wrong number The ordinary failure
wrong tool selection Picked a different tool than the gold program The one that compounds
inefficient trajectory More than 1.5x the oracle’s call count Costs money and grows the context quadratically

The pattern in the failures

Two things are visible in the ranked list.

The traps dominate the top, and they are rare. The high-severity band is almost entirely T4, and it is thin: 8 runs confabulated on a policy violation and 5 followed an injected instruction, against 576 plain wrong answers. Those 8 are the agent being asked for something policy would refuse and reporting success instead of the refusal. The server-side gate meant nothing actually happened, which is exactly why the gate is server-side. But the response was false, and only the behaviour axis catches that.

The cheap configurations fail differently, not just more. The floor row fails by picking the wrong tool. The mid-tier configurations increasingly fail by getting the trajectory right and the judgement wrong. That is the shape that says the remaining gap is not tool-calling syntax, and it is the single strongest argument in this project against fine-tuning as the next lever.

Attack and defence

The table a sceptical reader should read first.

“…” The answer
It is a toy world. Three worlds, one never trained on, and the transfer drop is reported per configuration. The transferable artifact is the harness, not the world.
The judge judged itself. The headline metric is executed, not judged. Judges are family-disjoint, dropped seats are recorded, and self-review is a tagged ablation with a measured penalty.
The evals are contaminated. The hidden split’s SHA-256 is committed in a git tag whose timestamp predates every optimisation run. Decontamination runs in CI on three axes and currently finds zero leaking pairs.
The headline is cherry-picked. Full matrix, paired intervals on every cell, per-tier and per-world breakdowns, 91 corrected comparisons, and this page.
You trained on frontier outputs. Nothing was trained. The licence firewall fails the build if a forbidden model ever appears as the generator of a training row, and it is armed with nothing to scan, which is the expected state.
Cheap models are just worse. On cost per success they are not: the all-cheap row is $0.00113 against the cascade’s $0.01464, thirteen times better on that ratio. It also fails four tasks in ten. Cost per success prices the successes and says nothing about what the failures cost you, which is why this project publishes both columns and refuses to rank on one.
The numbers are simulated. Yes, and every page says so. The code path is the production one; the priors are published model-card figures; --provider live regenerates all of it for real.
