Frequently Asked Questions
- How much VRAM does Nemotron Orchestrator 8B need?
Nemotron Orchestrator 8B requires 5.4 GB of VRAM at Q4_K_M, or 8.6 GB at Q8_0. Full 41K context adds up to 5.7 GB (11.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8B × 4.8 bits ÷ 8 = 4.8 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 6.3 GB (at full 41K context)
VRAM usage by quantization

- Can I run Nemotron Orchestrator 8B on a Mac?
Nemotron Orchestrator 8B requires at least 4 GB at Q2_K, 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 Nemotron Orchestrator 8B locally?
Yes — Nemotron Orchestrator 8B can run locally on consumer hardware. At Q4_K_M quantization it needs 5.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Nemotron Orchestrator 8B?
At Q4_K_M, Nemotron Orchestrator 8B can reach ~540 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~121 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 ÷ 5.4 × 0.55 = ~540 tok/s
