VoiceArena launched Diarization Bench to compare 12 diarization systems on the same real-world audio and scoring rules. It exposes how quickly accuracy drops with overlap and more speakers.

NVIDIA Nemotron 3 scores 4.29% DER with a 250 ms collar. Score the exact same output at 0 ms and it becomes 14.72%.
