Stable Task identities and signatures

Style and substance

KFA Task ID: benchmark-task-scout-39034ef55c3039184d6dfa99

Source or catalog identity: mt-bench-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-68937a3b9ddd34b25374820f

Source or catalog identity: mt-bench-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.

Tie and uncertainty

KFA Task ID: benchmark-task-scout-a42072e734dff25aa34a0b07

Source or catalog identity: mt-bench-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.

Multi-turn quality

KFA Task ID: benchmark-task-scout-f2361781b1c5a3e4289989aa

Source or catalog identity: mt-bench-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.
