02How much VRAM it needs (estimate)

Total = weights + 10% + 0.5GB overhead + KV cache for one request (FP16 KV). More concurrent users multiply the KV column.

BF16 / FP16 (original)7.5 GB 9.1 GB10.0 GB 12GB GPUMac 16GB
FP8 / INT8 / Q8_04.0 GB 5.2 GB6.1 GB 8GB GPUMac 16GB
4-bit (Q4_K_M / AWQ / GPTQ-Int4)2.3 GB 3.3 GB4.2 GB 8GB GPUMac 16GB

KV cache per request: 8K 0.3 GB · 32K 1.2 GB

Bits per weight: BF16 16, FP8 8.5, 4-bit 4.85. “Fits” = total ≤ 90% of memory; Mac GPU can use ~2/3 of unified memory (≤36GB) or ~3/4 (larger). For MoE, all experts must be in memory, so size by total parameters. Method →
