Strengths & weaknesses

Strengths

  • Persona set by text prompt, voice by audio conditioning
  • Listens and speaks at once, with barge-in
  • Open weights, ready for commercial use per NVIDIA

Weaknesses

  • English only
  • Big Bench Audio 19.1% (AA)
  • Gated Hugging Face download; self-host only

Not notable: #42 on AA Big Bench Audio (19.1%). Release date per the model card (2026-01-15); secondary coverage says 2026-01-20. Licence: NVIDIA Open Model License Agreement, with additional information under CC-BY-4.0. The GitHub repo ships pre-packaged voice prompts (NATF0-3, NATM0-3, VARF0-4, VARM0-4), but the model card gives no count, so voices is null.
