MT-Bench

The 80 two-turn questions are fixed, public, and heavily exercised across research and leaderboards, so the test set is both widely memorized and increasingly saturated (top models score 8.5–9.0 on a 1–10 scale where 9 is a realistic ceiling). It remains a standard, still-discriminative LLM-judge eval, but the fixed set is the constraint: refreshed or held-out variants are the future direction.
