Frequently Asked Questions
- How much VRAM does NuExtract need?
NuExtract requires 8.8 GB of VRAM at BF16. Full 4K context adds up to 0.8 GB (9.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 3.8B × 16 bits ÷ 8 = 7.6 GB
KV Cache + Overhead ≈ 1.2 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 2 GB (at full 4K context)
VRAM usage by quantization
BF168.8 GBBF16 + full context9.6 GB- Can I run NuExtract on a Mac?
NuExtract requires at least 8.8 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 NuExtract locally?
Yes — NuExtract can run locally on consumer hardware. At BF16 quantization it needs 8.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is NuExtract?
At BF16, NuExtract can reach ~333 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~75 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 ÷ 8.8 × 0.55 = ~333 tok/s
Estimated speed at BF16 (8.8 GB)
~333 tok/s~75 tok/s~249 tok/s~206 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of NuExtract?
At BF16, the download is about 7.64 GB.
- Which GPUs can run NuExtract?
28 consumer GPUs can run NuExtract at BF16 (8.8 GB). Top options include AMD Radeon RX 6800, AMD Radeon RX 6800 XT, AMD Radeon RX 6900 XT, AMD Radeon RX 6700 XT. 17 GPUs have plenty of headroom for comfortable inference.
- Which devices can run NuExtract?
27 devices with unified memory can run NuExtract at BF16 (8.8 GB), including Mac Mini M4 (16 GB), Mac Mini M4 (32 GB), Mac Mini M4 Pro (24 GB), Mac Mini M4 Pro (48 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
