AlpacaEval
AlpacaEval is identified by its primary project source as an evaluation family covering instruction preference and pairwise evaluation. This entry publishes independently authored task signatures only.
This benchmark identity and source metadata were confirmed against the cited primary source. Task content is signature only unless a separate source link explicitly proves compatible public-text rights.

Stable Task identities and signatures
Style and substance
KFA Task ID: benchmark-task-scout-0f62e5b412410fdf6d469717
Source or catalog identity: alpacaeval-style-and-substance
Evaluate whether an agent can balance response style with factual and task quality in a comparative response evaluation. Success is determined when the judgment follows the rubric rather than surface verbosity.
Pairwise preference
KFA Task ID: benchmark-task-scout-addc5a090e288c327dd36f54
Source or catalog identity: alpacaeval-pairwise-preference
Evaluate whether an agent can select the response preferred under a declared human rubric in a blinded pairwise evaluation. Success is determined when the selection matches the recorded preference.
Multi-turn quality
KFA Task ID: benchmark-task-scout-d2b4d497b7893b098f42d515
Source or catalog identity: alpacaeval-multi-turn-quality
Evaluate whether an agent can sustain helpfulness and coherence across a conversation in a multi-turn dialogue evaluation. Success is determined when the dialogue satisfies the declared judging rubric.
Tie and uncertainty
KFA Task ID: benchmark-task-scout-dd7ae54e7105d48356063112
Source or catalog identity: alpacaeval-tie-and-uncertainty
Evaluate whether an agent can recognize when two candidate responses are not meaningfully distinguishable in a preference task permitting ties. Success is determined when the judgment matches the declared tie policy.
