Baseten 上线 NVIDIA Nemotron 3 Diarization,单卡可跑 500 路实时说话人分离
Baseten 在 Model Library 上线 NVIDIA Nemotron 3 Diarization,提供预录、流式和实时转写三种预设,单次推理即可标注最多 8 位说话人,间隔最低 320ms。该模型约 100M 参数,基于 NVIDIA Streaming Sortformer,同一 checkpoint 支持 0.32 至 30.4 秒四档算法延迟;在 RTX PRO 6000 上可维持 500 路以上并发分离流,加入转写后为 190 路。AISHELL-4 低延迟档 DER 为 9.8%,对比 Streaming Sortformer v2.1 的 27.2%,模型已在 Hugging Face 和 Baseten Model Library 开放。
llar. The benchmarking results highlight consistent stability across multiple benchmark datasets in multiple languages, such as NOTSOFAR, AMI, CALLHOME, and AISHELL, outperforming Meta Muse Voice Transcribe on all datasets at even the ultra-low configuration, and losing to pyannote Community-1 only on AMI. Even under ultra-low latency configurations, the error rate remains within a tight margin of offline baselines, confirming robust speaker attribution under real-time constraints. Streaming dia
