GLM-5.2 744B — VRAM, Speed & Local Setup

Model library → GLM-5.2 → GLM-5.2 744B

The full GLM-5.2 MoE. At 744B total parameters this needs roughly 400 GB even at Q4 — a multi-node or datacenter deployment, not a workstation, despite the modest ~40B active count. Reach it through the Z.ai API or a hosted provider unless you have that hardware. The 1M-token context and MIT license are what set it apart from other models at this scale.

GLM-5.2 744B needs about 450 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

VRAM and Speed by Quantization

Modelled on a reference NVIDIA RTX 4090 (24 GB), with no KV cache (this record has no published architecture). Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.

GLM-5.2 744B — Frequently Asked Questions

How much VRAM does GLM-5.2 744B need?
About 450 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does GLM-5.2 744B run on an RTX 4090 (24 GB)?
No. GLM-5.2 744B needs about 450 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.
How do I run GLM-5.2 744B locally?
Install Ollama and run `ollama run glm-5-2`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
