    Understand

    Plain-language record, transferred from the reviewed source module.

    What changed. The open benchmark expanded to roughly 16 categories with programmatically verified terminal tasks; Scale reports that the best frontier systems solve fewer than 40% of the tasks.

    Technique / discovery. Isolated sandboxes, end-state verification, expert-authored tasks, and rollout failure analysis.

    Apply

    Professional implication, only where the reviewed record states one.

    Why it matters. Evaluation is moving toward executable, economically relevant work where plausible narratives do not earn credit.

    Application. Coding, science, finance, systems, and security agents

    Verify

    Evidence status, stated limitations, and the external sources this record actually carries.

    Evidence maturity. Benchmark (source tier A)

    Identified bottleneck. Agents often choose the wrong method or assumptions even when they can execute a correct plan.

    Caveat / evidence note. Task construction is partly contributed by Scale, which also benefits commercially from evaluation demand.

    Review status. Reviewed. User requested: Yes.
