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) | 72.3 GB | 82.2 GB | 88.6 GB | 114 GB | RTX PRO 6000 96GB | Mac 128GB |
| FP8 / INT8 / Q8_0 | 38.4 GB | 44.9 GB | 51.3 GB | 77.1 GB | 2 × RTX 5090 (64GB) | Mac 128GB |
| 4-bit (Q4_K_M / AWQ / GPTQ-Int4) | 21.9 GB | 26.8 GB | 33.2 GB | 59.0 GB | RTX 5090 32GB | Mac 64GB |
KV cache per request: 8K 2.1 GB · 32K 8.6 GB · 128K 34.4 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 →
