Question 1

How much VRAM does glm-4-9b need?

Accepted Answer

glm-4-9b (9.4B) requires approximately 21.010528635978698 GB of VRAM at full precision (FP16), 10.5 GB at 8-bit quantization (Q8), and 5.3 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run glm-4-9b?

Accepted Answer

We have 10 compatible GPUs indexed for glm-4-9b, including L4, A40, A100 40GB, A10G, A10 and 5 more. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run glm-4-9b?

Accepted Answer

The cheapest GPU to run glm-4-9b in the cloud is the L4 at $0.20/hr. Other affordable options include A40 ($0.44/hr) and A100 40GB ($0.93/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can glm-4-9b run on consumer hardware?

Accepted Answer

glm-4-9b may be able to run on high-end consumer GPUs like the RTX 4090 (24 GB) with 4-bit quantization (Q4), which reduces VRAM usage to approximately 5.3 GB. However, performance may be limited compared to datacenter GPUs.

Question 5

What quantization options are available for glm-4-9b?

Accepted Answer

glm-4-9b supports the following quantization levels: FP16 (full precision): ~21.010528635978698 GB, Q8 (8-bit): ~10.5 GB, Q6 (6-bit): ~7.9 GB, Q4 (4-bit): ~5.3 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression.
