FAQ
Can the NVIDIA RTX A4000 run NVIDIA Nemotron 3 Nano 4B BF16?
Yes. The NVIDIA RTX A4000's 16.0GB of VRAM is enough to run NVIDIA Nemotron 3 Nano 4B BF16 at Q8_0 quantization (5.3GB required).
What's the best quantization to use?
Q8_0 is the highest-precision quantization that fits in your 16.0GB. It uses about 5.3GB of memory and 6.8GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
