Frequently Asked Questions
- How much VRAM does Hermes 3 Llama 3.1 70B Lorablated need?
Hermes 3 Llama 3.1 70B Lorablated 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)
KV Cache + Overhead ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M43.3 GBQ4_K_M + full context85.6 GB- Can NVIDIA GeForce RTX 5090 run Hermes 3 Llama 3.1 70B Lorablated?
Yes, at Q2_K (31.0 GB) or lower. Higher quantizations like Q3_K_M (35.4 GB) exceed the NVIDIA GeForce RTX 5090's 32 GB.
- What's the best quantization for Hermes 3 Llama 3.1 70B Lorablated?
For Hermes 3 Llama 3.1 70B Lorablated, Q4_K_M (43.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (51.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 31.0 GB.
