FAQ
Can the Apple M3 Ultra (192GB) run Nemotron 3 Nano Omni 30B A3B Reasoning BF16?
Yes. The Apple M3 Ultra (192GB)'s 192GB of unified memory is enough to run Nemotron 3 Nano Omni 30B A3B Reasoning BF16 at fp16 quantization (61.0GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 192GB. It uses about 61.0GB of memory and 62.5GB 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.
