Running GLM 5.2 on DGX Station
GLM 5.2 has 744 billion parameters. DGX Station offers 748 GB of HBM3e and LPDDR5X memory. This page puts the two side by side.
How much memory does GLM 5.2 need?
Weights take the parameter count multiplied by the format size, plus a 15% runtime margin for activations and buffers. The attention cache sits on top: it grows with context length and with the number of concurrent requests, so it is sized case by case.
| Format | Weights in memory | On this machine | What the format costs |
|---|---|---|---|
| FP16 | 1,711 GB | does not fit | full precision, the quality reference |
| FP8 | 856 GB | does not fit | negligible loss on most tasks |
| NVFP4 | 428 GB | fits | Blackwell format, native FP4 compute |
| Q4 | 428 GB | fits | block quantisation, broadly supported |
What is left to serve requests?
GLM 5.2 fits on DGX Station only when quantised. In NVFP4, its weights take about 428 GB of 748 GB. More precise formats do not fit. The remaining margin decides how many concurrent requests and how much context the machine sustains. A margin below a quarter of memory forces a limit on context or on concurrency.
DGX Station ranges from 117 to 169 k€, indicative and not contractual. The machine targets the PME segment.
