Nemotron 3 Diarization
A 100M-parameter open-weight speaker diarization model handling up to 8 speakers for both live and recorded audio.
Overview
NVIDIA released Nemotron 3 Diarization on September 23, 2026, a 100-million-parameter open-weight model that assigns anonymous speaker labels to overlapping speech, expanding support from 4 to 8 speakers versus its predecessor. It offers four configurable latency modes (30.4s, 1.04s, 0.64s, 0.32s) and works as one model for both offline and streaming conversations. It ranked #1 on VoiceArena's Diarization-Bench with a 14.72% Diarization Error Rate, a 40% average relative DER reduction versus NVIDIA's previous baseline at 1.04-second latency, and a claimed 15,113x real-time factor speedup at batch size 32.
