Estimated VRAM requirement
Weight memory uses parameter count × bits per weight, plus a quantization overhead factor. KV cache uses standard GQA formulas. Values are calculated estimates, not measured allocations.
| Quantization | Estimated weights | 2K total | 4K total | 8K total |
|---|---|---|---|---|
| FP16 | 17.6 GB | 20.4 GB | 21.0 GB | 22.3 GB |
| Q8 | 9.9 GB | 12.1 GB | 12.7 GB | 14.0 GB |
| Q6 | 7.7 GB | 9.7 GB | 10.4 GB | 11.7 GB |
| Q5 | 6.5 GB | 8.4 GB | 9.1 GB | 10.4 GB |
| Q4 | 5.4 GB | 7.3 GB | 7.9 GB | 9.2 GB |
| Q3 | 4.3 GB | 6.1 GB | 6.7 GB | 8.1 GB |
