Step-3.7-Flash: hardware requirements
Step-3.7-Flash needs about 139 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 | 139 GB | 139 GB | estimated |
| Q5_K_M | 143 GB | 163 GB | 163 GB | estimated |
| Q6_K | 165 GB | 188 GB | 188 GB | estimated |
| Q8_0 | 213 GB | 242 GB | 242 GB | measured |
| BF16 | 401 GB | 452 GB | 452 GB | measured |
“Measured” sizes are read from published GGUF files (stepfun-ai/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.
