| Quantization | Memory | Smallest cloud GPU | Quality |
|---|---|---|---|
| INT4 (Q4) | 403 GB | 8× H100 · $17.20/h | smallest footprint, minor quality loss |
| INT8 (Q8) | 805 GB | multi-node, over 640 GB | near-lossless |
| FP16 (full) | 1610 GB | multi-node, over 640 GB | reference quality |
At home: 403 GB in INT4 is beyond any desktop or Mac in our machines table, so it means a multi-GPU server.
