Nemotron 3 Nano Omni 30B A3B Reasoning BF16, GGUF

Nvidia Nemotron 3 Nano Omni 30B A3B Reasoning BF16 is a multimodal Mixture-of-Experts reasoning model designed for unified audio, vision, and language understanding, enabling AI agents to efficiently derive insights from videos and documents with high accuracy. The model integrates C-RADIOv4-H based vision and Parakeet audio encoders for efficient long-context processing and precise reasoning, supporting image, video, document, and speech reasoning tasks.

This repository holds Vultr's GGUF quantizations of it. They are hybrid quantizations: rather than applying one precision to the whole network, each layer's precision is chosen from a measured importance score, so the bits go where they change the output most.

The vision encoder is in Nemotron-3-Nano-Omni-30B-A3B-Reasoning-mmproj-f16.gguf (2.99 GB). llama.cpp downloads it automatically with the command under Run, so image input works without extra steps.

KL divergence measures how far a quantized model's next-token probabilities drift from those of the original bf16 model, averaged over every token of the evaluation text. The lower the value, the closer the quantized model is to the original; zero would mean identical output.

Evaluation

Every variant in this repository was evaluated against the original bf16 model for perplexity, KL divergence, top-token agreement, HellaSwag and WinoGrande, under identical conditions. The full results are maintained on the model's page in the Vultr Model Library:

https://docs.vultr.com/models/nvidia-nemotron-v3/nemotron-3-nano-omni-30b-a3b-reasoning?tab=quantized

That page is the reference for these files. The summary above is an excerpt from it.

Run

The model's chat template is embedded in every file, so no extra prompt formatting is needed.
