VRAM Requirements
| Quantization | VRAM | Use case |
|---|---|---|
| Q4_K_M | 46 GB | Basic inference, 4K context |
| Q5_K_M | 56 GB | Good quality, 8K+ context |
| Q8 | 89 GB | Near-lossless, 16K+ context |
| FP16 | 175 GB | Full precision, max quality |
Formula: params × bytes_per_param × 1.2 overhead + 2 GB base. Actual requirements vary by framework and context length.
