All three quants
16GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 2.4 GiB | 3.9 GiB | Fits comfortably | 12.1 GiB |
| Q8_0near-lossless | 4.2 GiB | 5.7 GiB | Fits comfortably | 10.3 GiB |
| FP16full weights | 8.0 GiB | 9.5 GiB | Fits comfortably | 6.5 GiB |
Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
