RFMC - English-Chinese: leaderboard

Medical-domain translation from English into Simplified Chinese on the Reeve Foundation Multilingual Corpus (RFMC; Balashov, VanHorn, Xu and Downes, University of Georgia, EAMT 2026): the 1,143 sentences of Chapter 1 of the Reeve Foundation's Paralysis Resource Guide are translated one call per sentence with a fixed zero-shot prompt and no context, and the whole output is scored with COMET-22 against the foundation's Chinese translation, partly updated by the authors for the 2023 edition. The score is document-level COMET-22 x100 (higher is better); local open-weight models run through Ollama, mostly at 4-bit quantization, reasoning models at their default temperature, and failed calls count as empty lines.

Metric: COMET-22 (x100; document-level mean over 1,143 medical-domain sentences, English into Chinese, professional reference translations). Source: arxiv.org. Saturation forecast: Estimated already saturated. 13 models tracked.
