GLM-4 9B needs ~6.8 GB VRAM. RTX 2060 6GB has 6.0 GB. With Q3_K_S quantization, expect ~24 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.

Offload
20%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.5 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 2060 6GB can run GLM-4 9B at Q3_K_S quantization (Very compromised (needs ~0.5 GB host RAM)). The recommended Q4_K_M requires 7.9 GB which exceeds available memory, but at Q3_K_S it needs only 6.8 GB. Expected decode speed: 24.3 tok/s.
GLM-4 9B (9B parameters) requires approximately 7.9 GB at Q4_K_M quantization. On RTX 2060 6GB, it fits at Q3_K_S using 6.8 GB.
The recommended quantization is Q4_K_M, but on RTX 2060 6GB the best fitting quantization is Q3_K_S, which uses 6.8 GB.
On RTX 2060 6GB, GLM-4 9B achieves approximately 24.3 tokens per second decode speed with a time-to-first-token of 7961ms using Q3_K_S quantization.
For coding workloads, GLM-4 9B on RTX 2060 6GB receives a F grade with 15.2 tok/s and 4K context.
On RTX 2060 6GB, GLM-4 9B can safely use up to 4K tokens of context at Q3_K_S quantization. The model's official context limit is 128K, but available memory constrains the safe maximum.
