Can I Run GLM-4 9B on NVIDIA GeForce RTX 3090?
作者： Jakub Rusinowski · 最后更新： 2026年9月19日
Yes. GLM-4 9B needs 5.4 GB at Q4_K_M and the NVIDIA GeForce RTX 3090 has 24 GB, leaving about 18.6 GB of headroom, at roughly 79 tok/s (estimated) with room for up to 64K of context.

Assumes a 4K-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 24 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 3090: 8K 7.4 GB · 32K 11.1 GB · 125K 25.1 GB ✗. Past 125K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
