P3B3 (pt-BR Prompt): leaderboard

P3B3 (2026) measures European versus Brazilian Portuguese variety bias and controllability in expert-written, variety-agnostic multi-turn dialogues. This board scores the replies when the first turn asks for Brazilian Portuguese, on a scale from 0 (Brazilian) to 100 (European Portuguese) judged by Gemini 3 Flash; lower is better, meaning the model follows the requested variety.

Metric: Variety score (0-100), where 0 is Brazilian and 100 European Portuguese, of the model replies when the first turn asks for Brazilian Portuguese; Gemini-3-Flash judge, Portuguese category-based single-turn prompt, averaged over 203 turns; greedy decoding; lower is better (follows the requested variety). Source: arxiv.org. Saturation forecast: Estimated already saturated. 20 models tracked.
