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.
| Precision | Weights | Total @ 8K | Total @ 32K | Smallest GPU | Mac |
|---|---|---|---|---|---|
| BF16 / FP16 (original) | 147 GB | 165 GB | 173 GB | 4 × RTX PRO 6000 (384GB) | Mac 256GB |
| FP8 / INT8 / Q8_0 | 78.0 GB | 89.0 GB | 97.0 GB | H200 141GB | Mac 256GB |
| 4-bit (Q4_K_M / AWQ / GPTQ-Int4) | 44.5 GB | 52.1 GB | 60.2 GB | 2 × RTX 5090 (64GB) | Mac 128GB |
KV cache per request: 8K 2.7 GB · 32K 10.7 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 →
