Frequently Asked Questions
- How much VRAM does Plutus 8B Instruct need?
Plutus 8B Instruct requires 17.0 GB of VRAM at FP16. Full 131K context adds up to 16.9 GB (33.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.2B × 16 bits ÷ 8 = 16.4 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 17.5 GB (at full 131K context)
VRAM usage by quantization
FP1617.0 GBFP16 + full context33.9 GB- Can I run Plutus 8B Instruct on a Mac?
Plutus 8B Instruct requires at least 17.0 GB at FP16, 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 Plutus 8B Instruct locally?
Yes — Plutus 8B Instruct can run locally on consumer hardware. At FP16 quantization it needs 17.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Plutus 8B Instruct?
At FP16, Plutus 8B Instruct can reach ~172 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 ÷ 17.0 × 0.55 = ~172 tok/s
