This suggests the models rely on qualitatively different exploitation strategies, and that an ensemble approach could substantially expand coverage beyond what any one model achieves. More budget helps, but only for the best models. When we extended the budget from two to six hours, Claude Mythos Preview kept climbing from 127 to 204 successful exploits with no clear plateau. Claude Opus 4.6, by contrast, flatlined at around 15 within the first 30 minutes. Th

er benchmarks? Because there is no universally best agent. Every frontier model, including Fable 5, has domains where it shines and domains where it struggles. Aggregate scores average over 55 occupations and 1,500+ tasks, causing many models to cluster together. But the average is not the story. The real signal lies in where agents succeed, where they fail, and how those patterns differ across domains. On identical tasks, different models often fail for very different reasons.

This transition raises questions that no benchmark can answer by itself: What becomes the developer’s highest-leverage work when agents do most of the coding?; Is software that ships without human code review a mature engineering practice or a risk we do not yet know how to measure?; Do agents democratize software creation, or relocate expertise into specification, evaluation, architecture, and governance?; Who is accountable when

Vero uses full solve as the primary outcome because partial specification coverage can be inflated by easier obligations. In code-and-proof mode, an unproved specification can indicate either a missing proof or an implementation that does not pass the specification. Per-specification coverage remains useful diagnostically, but only complete coverage certifies the submitted implementation against

This is because failed sandbagging doesn’t have an unambiguous “benign” label: These runs are not actually sandbagging but they still behave differently from benign runs, so they’re not quite benign either. We find that zero-shot prompted monitors achieve underwhelming true positive rate (i.e. recall) at a given

Crucially, this enables fine-grained analysis of auditing methodologies: If we want to validate whether an auditing tool is useful, we can simply measure whether, on average across many attempts, access to this tool improves an auditing agent’s performance on a standard auditing testbed.

We also introduce three environments that formalize alignment auditing workflows as auditing games, and use them to evalu

There are many opportunities for future work to improve data filtering. Our approach uses a classifier to determine wh
