Can I run GLM-4.6 on Nvidia GeForce RTX 4070 (12GB)?
No. GLM-4.6 needs ~221.3 GB even at Q4_K_M, but Nvidia GeForce RTX 4070 (12GB) only has ~11 GB usable.
Needs ~221.3 GB even at Q4_K_M, but only ~11 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 210.3 GB: GLM-4.6 needs roughly 221.3 GB at Q4_K_M and Nvidia GeForce RTX 4070 (12GB) leaves only about 11 GB usable for a model. No single tracked device has enough memory; GLM-4.6 needs a multi-GPU or high-memory rig.

FAQ
Can Nvidia GeForce RTX 4070 (12GB) run GLM-4.6?
No. GLM-4.6 needs ~221.3 GB even at Q4_K_M, but Nvidia GeForce RTX 4070 (12GB) only has ~11 GB usable.
How much memory does GLM-4.6 need?
Nvidia GeForce RTX 4070 (12GB) does not have enough memory. At Q4_K_M the weights are ~216 GB; with KV cache and runtime overhead, budget ~221.3 GB at a 4k context. It is a Mixture-of-Experts model (357B total / 32B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run GLM-4.6 on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
