Can I Run GLM-5 744B on NVIDIA GeForce RTX 5090?
Written by Jakub Rusinowski · Last updated September 29, 2026
No. GLM-5 744B needs 455.2 GB at 8K context (449.2 GB weights + 6 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 5090 has only 32 GB. No quantization we publish closes a gap that size.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 32 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 5090: 8K 455.2 GB ✗ · 32K 470.9 GB ✗ · 128K 533.7 GB ✗. Past 8K it no longer fits 32 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Step down to a smaller size in this family — no single consumer card we track fits this one.
