CCiV (Direct) - Structural Accuracy: leaderboard

Metric: Structural accuracy (%, 0-100): a poem counts when its line count and the character count of every line exactly match the target template (non-Chinese characters removed) of the standard form or of any documented historical variant of the requested Cipai; direct prompt: only the Cipai name and the theme; 300 prompts (10 historical themes for each of the 30 most frequent Cipai tune patterns), three samples each at temperature 0.7 and top-p 0.95, averaged; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 17 models tracked.
