All three quants
24GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 5.2 GiB | 6.7 GiB | Fits comfortably | 17.3 GiB |
| Q8_0near-lossless | 9.1 GiB | 10.6 GiB | Fits comfortably | 13.4 GiB |
| FP16full weights | 17.2 GiB | 18.7 GiB | Fits comfortably | 5.3 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.
