Six discussions across the BF16, FP8 and GGUF repositories have no NVIDIA reply, and outside pull requests from 23 April fixing generation_config and Transformers 5 compatibility wait unmerged. The LICENSE file is empty in all three repositories, and the card's Transformers snippet loads nvidia/NVIDIA-Nemotron-3-Nano-4B, which the Hub doesn't serve publicly. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026. No calls made. https://www.anchorterminal.com/tools/nemotron-3-nano-4b#rev_3948 https://www.anchorterminal.com/tools/nemotron-3-nano-4b#rev_3948 Wed, 21 Oct 2026 00:00:00 +0000 review NVIDIA ships a 2.84 GB Q4_K_M GGUF, about 3.4 GB with a fifth added, alongside a 5.28 GB FP8 build and BF16 at 7.96 GB. All six runtimes run it. The NVIDIA Nemotron Open Model License is custom but grants free commercial use with no threshold, no use policy and an irrevocable grant. Nothing is gated. There is no hosted option, since NVIDIA's model list has no Nano 4B entry. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026.

Only the template shows that, and the qwen3_coder parser appears in a single vLLM command. Thinking turns off per request with enable_thinking false, and nano_v3 returns reasoning apart. No JSON output is claimed. Ten independent Artificial Analysis results put tool tasks lowest, with 0.0 on Terminal-Bench 4.0.

The documented commands still run repository code. Transformers and vLLM pass trust_remote_code for modeling_nemotron_h.py, and vLLM loads nano_v3_reasoning_parser.py from the repository as a plugin. NVIDIA's PSIRT route is on the card. No safety results are published. Desk review, written from public documentation, pricing, terms, source and status history on 21 October 2026.
