Question 1

How much VRAM does GLM-5.3-Flash-FP4-Local need?

Accepted Answer

GLM-5.3-Flash-FP4-Local (175.2B) requires approximately 391.6901425436139 GB of VRAM at full precision (FP16), 195.8 GB at 8-bit quantization (Q8), and 97.9 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-5.3-Flash-FP4-Local?

Accepted Answer

We currently have no compatible GPUs indexed for GLM-5.3-Flash-FP4-Local. This may be because the model's VRAM requirements exceed available GPUs in our database, or VRAM data hasn't been computed yet.

Question 3

What is the cheapest GPU to run GLM-5.3-Flash-FP4-Local?

Accepted Answer

We don't currently have cloud pricing data for GPUs compatible with GLM-5.3-Flash-FP4-Local. Cloud pricing data is updated regularly — check back soon.

Question 4

Can GLM-5.3-Flash-FP4-Local run on consumer hardware?

Accepted Answer

GLM-5.3-Flash-FP4-Local requires approximately 391.6901425436139 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 97.9 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so GLM-5.3-Flash-FP4-Local requires datacenter or cloud GPUs.

Question 5

What quantization options are available for GLM-5.3-Flash-FP4-Local?

Accepted Answer

GLM-5.3-Flash-FP4-Local supports the following quantization levels: FP16 (full precision): ~391.6901425436139 GB, Q8 (8-bit): ~195.8 GB, Q6 (6-bit): ~146.9 GB, Q4 (4-bit): ~97.9 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.
