The math for Llama 3.1 8B at Q4_K_M

Weights: 8.03B params × 4.8 bits/weight ÷ 8 = 4.82 GB
+ loading overhead (10%): 0.48 GB
+ KV cache @ 4,096 ctx: 0.54 GB
= 5.84 GB VRAM required

Basis: calculated from verified architecture config (Params 8.03B, 32 layers, 8 KV heads, 128 head dim, 131072 context — HF config.json (NousResearch/Meta-Llama-3.1-8B-Instruct).). GPU VRAM/bandwidth figures are vendor specifications from our database. This tool never guesses throughput — see measured benchmarks for speed.
