Every change that can move a score: new task types, harder tasks, sharper checks, and changes to how we grade. If a number on the site moved, the reason is here.

  1. Scoring

    Every task type now shows what you get for the cost

    Task pages plot each setup's score against what an output costs at list price, as a multiple of the cheapest setup, and name the best value: the cheapest setup within 5 points of the leader at half its cost or less. Cost never changes a score.

    No change to scores.

  2. Scoring

    Checks now come from how the best product leaders judge the work

    Every task type is now graded on how world-class product and growth leaders work, as they've described it on Lenny's Podcast, with the leader credited by name beside each check. Fifteen new checks join, and task types are grouped into five domains: Product Craft, Growth, Metrics & Experimentation, Strategy and Leadership. A task type now also needs three reviewed verdicts on every one of its checks before it counts as calibrated, so most are provisional until the new checks are reviewed.

    Every score was recalculated.

  1. Scoring

    Scores now come only from the graders' checks

    The Combined score is now the share of checks an output passes, averaged across the decision model and the LLM judge, and capped at 40 for a critical failure. Our PM no longer scores outputs; they check the checkers. A task type counts as calibrated once the graders agree with them on at least 80% of checks.

    Every score was recalculated.

  2. Checklist

    Every task type gets a practitioner check

    Each task type now has one check for the sharpest thing experienced product leaders say about doing that job well, such as diagnosis before prescription for strategy, or trusting the data before reading an experiment. Every output was re-graded with it.

    Scores on these task types changed: every output was re-graded.

  3. Grader

    Prototypes are tested in a real browser, design included

    One-shot prototypes are now opened in a headless browser, which tries the task's core flow and answers the browser checks. It also checks two signs of templated design: the stock AI palette, and grids of near-identical cards.

    Scores on these task types changed: every output was re-graded.

  4. Grader

    An independent LLM judge now grades alongside the decision model

    Every written output is also graded by an LLM judge from a model family we don't test, so it isn't marking its own homework. It checks each claim against the brief, then answers every check yes or no.

    Every score was recalculated.

    Every task type

  5. Scoring

    The benchmark starts with eight task types

    PRDs, strategy, discovery synthesis, one-shot prototypes, activation reviews, experiment readouts, challenging an idea and sticking to a plan, each graded check by check by the decision model.

    New scores. Existing scores didn't change.
