Phun-Bench - Rhyming Sentence Generation (1-Rhyme): leaderboard
Phun-Bench (2026) tests whether text-only language models understand the sound of Chinese words, using tasks that cannot be solved by memorized pinyin alone. Rhyming Sentence Generation asks for a new sentence whose last character rhymes with a reference lyric line under a fixed set of 18 rhyme groups; exact-match rate in percent, higher is better.
Metric: Exact-match rate (%) of the rhyme group of the generated sentence's last character with the reference lyric line (1,000 lines; copying the reference ending disqualifies); thinking models run on 300 sampled items per setting, DeepSeek-V3 and GPT-4o on 500, the others on the full set; recommended sampling temperatures; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 9 models tracked.
