Running GLM 5.2 on RTX PRO 6000 server

GLM 5.2 has 744 billion parameters. RTX PRO 6000 server offers 768 GB of GDDR7 across 8 GPUs memory. This page puts the two side by side.

Short answer. GLM 5.2 fits on RTX PRO 6000 server only when quantised. In NVFP4, its weights take about 428 GB of 768 GB. More precise formats do not fit.

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. In NVFP4 the calculation reads: 744 billion parameters × 0.5 byte (NVFP4) = 372.0 GB of weights; × 1.15 runtime margin = 427.8 GB. 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.

Model sheet: 744 billion parameters, 40 billion active per token, 1,048,576-token context, MIT licence. 744 billion announced by Z.AI; the repository holds 753 billion tensor elements in BF16 (1,507 GB).

GLM 5.2 activates 40 billion parameters per token out of 744 billion. Active parameters govern speed, not footprint: every expert stays resident in memory. Confusing the two under-sizes the machine by an order of magnitude.

What is left to serve requests?

GLM 5.2 fits on RTX PRO 6000 server only when quantised. In NVFP4, its weights take about 428 GB of 768 GB. More precise formats do not fit. The remaining margin decides how many concurrent requests and how much context the machine sustains. By QDNA convention a machine “fits” when the weights take at most 75% of its memory; beyond that it “barely fits” and forces a limit on context or on concurrency. The attention cache is not calculated on this page. These models’ architectures (compressed latent, linear or sparse attention, Mamba layers) share no per-token formula; it is measured on the machine, with the target context and concurrency [TO BE MEASURED].

RTX PRO 6000 server: price on quotation. No manufacturer publishes a price for an 8-card server; the card alone is listed at $16,000 on the NVIDIA marketplace as of 1 September 2026 (as reported by thundercompute.com). The machine targets the PME, GE segment.
