Kimi K2 (1T MoE) has 1000 billion parameters. At standard 4-bit quantization with 8K context, it needs roughly 672.0 GB of VRAM — weights plus cache and runtime overhead.
VRAM by quantization
| Precision | Weights | Cache/Buffer | Total VRAM |
|---|---|---|---|
| 2-bit (IQ2_XXS) | 320.0 GB | 120.0 GB | 442.0 GB |
| 4-bit (Q4_K_M) | 550.0 GB | 120.0 GB | 672.0 GB |
| 8-bit (Q8_0) | 1050.0 GB | 120.0 GB | 1172.0 GB |
| 16-bit (FP16) | 2000.0 GB | 120.0 GB | 2122.0 GB |
