Fits comfortably at Q4_K_M.
Qwen3.5 9B is 9.65B parameters. At Q4_K_M the weights are about 5.4 GiB; with the 1.5 GiB runtime reserve that is 6.9 GiB against the card's 10GB, leaving about 3.1 GiB for context.
All three quants
10GB card| Quant | Weights | With reserve | Verdict | Headroom |
|---|---|---|---|---|
| Q4_K_Mthe everyday quant | 5.4 GiB | 6.9 GiB | Fits comfortably | 3.1 GiB |
| Q8_0near-lossless | 9.5 GiB | 11.0 GiB | Only with CPU offload | short 1.0 GiB |
| FP16full weights | 18.0 GiB | 19.5 GiB | Only with CPU offload | short 9.5 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.
