Frequently Asked Questions
- How much VRAM does Hermes 3 Llama 3.1 8B Q3 K S GGUF need?
Hermes 3 Llama 3.1 8B Q3 K S GGUF requires 3.9 GB of VRAM at Q3_K_S.
VRAM = Weights + KV Cache + Overhead
Weights = 8B × 3.5 bits ÷ 8 = 3.5 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q3_K_S3.9 GB- Can I run Hermes 3 Llama 3.1 8B Q3 K S GGUF on a Mac?
Hermes 3 Llama 3.1 8B Q3 K S GGUF requires at least 3.9 GB at Q3_K_S, 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 Hermes 3 Llama 3.1 8B Q3 K S GGUF locally?
Yes — Hermes 3 Llama 3.1 8B Q3 K S GGUF can run locally on consumer hardware. At Q3_K_S quantization it needs 3.9 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Hermes 3 Llama 3.1 8B Q3 K S GGUF?
At Q3_K_S, Hermes 3 Llama 3.1 8B Q3 K S GGUF can reach ~757 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~170 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 ÷ 3.9 × 0.55 = ~757 tok/s
