NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning GGUF size and VRAM requirements
unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF is a very large reasoning-focused model with 31.58 billion parameters, built on the nemotron_h_moe architecture. It is released under the other license and has been downloaded 14,525 times.
To run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF locally at a 4,096-token context, its quantized versions need between 2.9 GB (F16, lowest quality) and 34.39 GB (Q8_K_XL, highest quality) of memory, weights plus KV cache and a system margin included.
For most users the best balance is F32, needing about 4.38 GB. That means unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF fits entirely in the VRAM of a 6 GB GPU or larger, running fully on the GPU.

Frequently asked questions
How much VRAM do you need to run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF?
You need about 4.38 GB of VRAM to run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF entirely on the GPU using the F32 quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF on an 8 GB GPU?
Yes. With 8 GB of VRAM you can run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF fully on the GPU using F32 (about 4.38 GB).
Can I run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF fully on the GPU using F32 (about 4.38 GB).
Can I run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF fully on the GPU using Q4_K_XL (about 23.71 GB).
What is the best quantization for unsloth/NVIDIA-Nemotron-3-Nano-Omni-30B-A3B-Reasoning-GGUF?
If memory allows, higher bits-per-weight means better quality. A common sweet spot is a Q4_K_M or Q5_K_M quantization, which keeps most of the quality while roughly halving the memory versus 8-bit. Pick the highest quantization that still fits in your VRAM.
