How much RAM does Step-3.7-Flash need?

Step-3.7-Flash needs about 140 GB of memory at Q4_K_M quantization with 4K context. The download itself is 122 GB; the extra covers the context cache and runtime overhead.

Can I run Step-3.7-Flash on a laptop?

Not on typical consumer hardware. Step-3.7-Flash needs 140 GB, which is beyond a normal laptop or desktop.

Step-3.7-Flash: hardware requirements

Step-3.7-Flash needs about 140 GB of memory at Q4 quantization — a 122 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	122 GB	140 GB	140 GB	measured
Q5_K_M	146 GB	167 GB	167 GB	measured

“Measured” sizes are read from published GGUF files (unsloth/Step-3.7-Flash-GGUF). “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.
