All three quants
32GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 15.5 GiB | 17.0 GiB | Fits comfortably | 15.0 GiB |
| Q8_0near-lossless | 27.4 GiB | 28.9 GiB | Fits, tight on context | 3.1 GiB |
| FP16full weights | 51.8 GiB | 53.3 GiB | Only with CPU offload | short 21.3 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.
