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 | Total @ 128K | Smallest GPU | Mac |
|---|---|---|---|---|---|---|
| BF16 / FP16 (original) | 2.02 TB | 2.23 TB | 2.23 TB | 2.24 TB | 2 × 8 × B300 nodes (4,608GB) | — |
| FP8 / INT8 / Q8_0 | 1.08 TB | 1.18 TB | 1.19 TB | 1.20 TB | 8 × B200 (1,440GB) | — |
| 4-bit (Q4_K_M / AWQ / GPTQ-Int4) | 614 GB | 676 GB | 679 GB | 688 GB | 8 × H200 (1,128GB) | — |
KV cache per request: 8K 0.8 GB · 32K 3.0 GB · 128K 12.1 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 →
