Frequently Asked Questions

How much VRAM does Hermes 3 Llama 3.1 70B need?

Hermes 3 Llama 3.1 70B requires 43.3 GB of VRAM at Q4_K_M, or 142.1 GB at BF16. Full 131K context adds up to 42.3 GB (85.6 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 GB

KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 43.3 GB (at full 131K context)

Can I run Hermes 3 Llama 3.1 70B on a Mac?

Yes — Mac Studio M1 Max (32 GB) and 84 other Macs can run Hermes 3 Llama 3.1 70B, the smallest at IQ2_XS. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 43.3 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio M5 Max (48 GB).

Can I run Hermes 3 Llama 3.1 70B locally?

Yes — Hermes 3 Llama 3.1 70B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Hermes 3 Llama 3.1 70B?

At Q4_K_M, Hermes 3 Llama 3.1 70B can reach ~111 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 43.3 × 0.65 = ~120 tok/s
