Fits comfortably at Q4_K_M.
Qwen3 14B is 14.8B parameters. At Q4_K_M the weights are about 8.3 GiB; with the 1.5 GiB runtime reserve that is 9.8 GiB against the card's 12GB, leaving about 2.2 GiB for context.
All three quants
12GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 8.3 GiB | 9.8 GiB | Fits comfortably | 2.2 GiB |
| Q8_0near-lossless | 14.6 GiB | 16.1 GiB | Only with CPU offload | short 4.1 GiB |
| FP16full weights | 27.6 GiB | 29.1 GiB | Does not fit | short 17.1 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.
