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) | 47.1 GB | 53.7 GB | 57.7 GB | 2 × RTX 5090 (64GB) | Mac 128GB |
| FP8 / INT8 / Q8_0 | 25.1 GB | 29.4 GB | 33.4 GB | 2 × RTX 5090 (64GB) | Mac 64GB |
| 4-bit (Q4_K_M / AWQ / GPTQ-Int4) | 14.3 GB | 17.6 GB | 21.6 GB | RTX 4090 24GB | Mac 36GB |
KV cache per request: 8K 1.3 GB · 32K 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 →
