No. Even at Q4_K_M, GLM-5.3 needs about 457.8 GB, but the NVIDIA RTX 3080 Ti has 12 GB usable. You could offload some layers to system RAM, but it will be very slow.

Frequently asked questions

Can NVIDIA RTX 3080 Ti run GLM-5.3?

No. Even at Q4_K_M, GLM-5.3 needs about 457.8 GB, but the NVIDIA RTX 3080 Ti has 12 GB usable. You could offload some layers to system RAM, but it will be very slow.

How much VRAM does GLM-5.3 need?

About 457.8 GB at Q4_K_M with 8,192 tokens of context, and about 1507.3 GB at full FP16 precision.

How fast is GLM-5.3 on the NVIDIA RTX 3080 Ti?

It does not fit in the NVIDIA RTX 3080 Ti's memory, so most layers would run from system RAM and generation would be very slow.
