MSI-Bench - Mandarin: leaderboard
The Mandarin split of MSI-Bench (Xiong et al., 2026), which tests voice assistants on synthesized multi-party audio scenes that end in a request to the assistant, covering multi-speaker memory, instruction following and reasoning in 576 natively written cases. All-pass rate in percent: a case passes only when all its atomic rubrics, judged by DeepSeek V4 Pro, and any required tool call are correct; higher is better.
Metric: All-pass rate (%; all 576 Mandarin test cases over six multi-speaker memory, instruction-following and reasoning patterns; a case passes when all its atomic rubrics pass, judged by DeepSeek V4 Pro on the dialogue transcript, with a deterministic tool-call validator as one more rubric for cases that need a tool call; one prediction per model and case from the audio of a multi-party, multi-turn scene ending in an assistant-directed handoff; open-weight models served with JSON-schema constrained decoding). Source: arxiv.org. Saturation forecast: Around February 2027. 15 models tracked.
