Known issues we've tracked

Nemotron 3 now has dedicated sub-families for voice, retrieval, and safety beyond the original reasoning family. Published sub-lineup: (1) Nemotron Speech -- open-source ASR models, claimed 10x faster than class competitors at comparable WER; (2) Nemotron RAG -- multimodal embedding + reranker VLMs for enterprise retrieval; (3) Nemotron Safety -- Llama Nemotron Content Safety + Nemotron PII detector; (4) Nemotron 3 VoiceChat -- full-duplex voice agent in early access post-GTC 2026; (5) Nemotron 3 Content Safety guardrail. All released under the permissive Nvidia Open Model License
