How much RAM does GLM-5.1 need?

GLM-5.1 needs about 464 GB of memory at Q4_K_M quantization with 4K context. The download itself is 455 GB; the extra covers the context cache and runtime overhead.

Can I run GLM-5.1 on a laptop?

Not on typical consumer hardware. GLM-5.1 needs 464 GB, which is beyond a normal laptop or desktop.

GLM-5.1: hardware requirements

GLM-5.1 needs about 464 GB of memory at Q4 quantization — a 455 GB download plus room for context and overhead. That is beyond consumer hardware; use it through an API instead.

Download sizes by quantization

Lower quantization means a smaller file and less memory, at some cost to quality. Q4_K_M is the usual starting point. What is this?

Quant	Download	RAM @ 4K	RAM @ 32K	Source
Q4_K_Mrecommended	455 GB	464 GB	500 GB	estimated
Q5_K_M	534 GB	543 GB	579 GB	estimated
Q6_K	618 GB	627 GB	663 GB	estimated
Q8_0	801 GB	809 GB	846 GB	estimated
BF16	1508 GB	1516 GB	1553 GB	estimated

“Measured” sizes are read from published GGUF files. “Estimated” sizes are derived from the parameter count and are typically within a few percent. The RAM columns add the context cache and runtime overhead to the download size.
