Replace a single LLM judge with a multi-agent debate panel (CollabEval) to surface real issues

Future AGI·medium signal

Rather than one judge model, structured multi-agent evaluation runs several judges with different reasoning patterns that deliberate or debate, then synthesize a verdict — frameworks like CollabEval consistently beat single-LLM judges. Diverse reasoning makes the panel more likely to flag genuine defects that one model rationalizes away, and the debate transcript doubles as an audit trail. Reserve it for high-stakes evals where a wrong pass is expensive; use a cheap distilled judge for routine traffic.
