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) | 912 GB | 1.00 TB | 1.01 TB | 1.01 TB | 8 × H200 (1,128GB) | — |
| FP8 / INT8 / Q8_0 | 485 GB | 534 GB | 535 GB | 539 GB | 8 × H100 (640GB) | — |
| 4-bit (Q4_K_M / AWQ / GPTQ-Int4) | 276 GB | 305 GB | 306 GB | 310 GB | 4 × RTX PRO 6000 (384GB) | Mac 512GB |
KV cache per request: 8K 0.3 GB · 32K 1.3 GB · 128K 5.4 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 →
