NVIDIA Releases Nemotron 3.5 Transcribe for Promptable Multilingual

NVIDIA released Nemotron 3.5 Transcribe, an open-weight model on Hugging Face and ModelScope (October 28, 2026) that transcribes 40 languages, translates 31 to/from English, and attributes speakers in 13 languages-all via natural language prompts. The 30-billion-parameter model activates only 4 billion per token, topping open-weight benchmarks with 5.33% English WER and 18.26% diarization error rate across 21 languages. Granary v2 fine-tuning toolkit accompanies it.
