Frequently Asked Questions
- How much VRAM does Llama 3.1 Nemotron Safety Guard 8B v3 need?
Llama 3.1 Nemotron Safety Guard 8B v3 requires 16.6 GB of VRAM at BF16. Full 131K context adds up to 16.9 GB (33.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.0B × 16 bits ÷ 8 = 16.1 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 17.4 GB (at full 131K context)
VRAM usage by quantization
BF1616.6 GBBF16 + full context33.5 GB- Can I run Llama 3.1 Nemotron Safety Guard 8B v3 on a Mac?
Llama 3.1 Nemotron Safety Guard 8B v3 requires at least 16.6 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Llama 3.1 Nemotron Safety Guard 8B v3 locally?
Yes — Llama 3.1 Nemotron Safety Guard 8B v3 can run locally on consumer hardware. At BF16 quantization it needs 16.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Llama 3.1 Nemotron Safety Guard 8B v3?
At BF16, Llama 3.1 Nemotron Safety Guard 8B v3 can reach ~175 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~39 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 16.6 × 0.55 = ~175 tok/s
