Selection should reward contribution

Accuracy matters, but a positive model-breeding lab should also select for contribution to the surrounding ecology. A candidate that makes outputs clearer, reduces cost, improves learning, or produces reusable artifacts may be worth promoting even when its raw task score is only modestly better.

Metric set

MetricCollection method
Capability transferPre/post task without AI help.
Reuse rateHow often outputs become accepted artifacts.
Frugal gainMemory, latency, and energy improvement.
Explanation scoreHuman review of clarity and correctness.
Portfolio contributionNew niche covered or fallback strengthened.
pseudocode
FUNCTION positive_selection_score(candidate, incumbent)
    score = benchmark_delta(candidate, incumbent)
    score += learning_transfer_delta(candidate, incumbent)
    score += artifact_reuse_delta(candidate, incumbent)
    score += frugal_gain(candidate, incumbent)
    score += niche_contribution(candidate)
    RETURN score
END FUNCTION

Lab rule

Do not let a leaderboard hide the practical reasons a model exists. Keep a separate benefit card for every candidate.
