EYT-Bench (PersonaMem-v2) - Persona Alignment: leaderboard
EYT-Bench (Enjoy Your Talk, 2026) evaluates LLMs as multi-turn conversational partners with a persona-grounded user simulator and an independent LLM judge; each turn the target model predicts the user state before replying. Judge-rated persona alignment (style, values, culture, memory, security) on a 0 to 100 scale on the PersonaMem-v2 pool of free-text personas distilled from real conversations; higher is better.
Metric: Persona alignment (style, value, culture, memory, security) (0-100): judge rubric of five sub-indicators scored 0, 0.5 or 1 per turn, summed to 0-5, turn weighted with the first two turns at 0.10 each and rescaled to 0-100; multi-turn dialogues of up to 10 turns with a persona-grounded Gemini 3.1 Pro user simulator and a Gemini 3.1 Pro judge (reasoning effort high, temperature 0); PersonaMem-v2 pool (100 dialogues; personas are free-text paragraphs distilled from long real user-assistant interactions).
