NVIDIA A100 40GB PCIe does not meet the minimum VRAM requirement for Q4 inference of stepfun-ai/Step-3.5-Flash. Review the quantization breakdown below to see how higher precision settings impact VRAM and throughput.
NVIDIA A100 40GB PCIe lacks sufficient VRAM for comfortable stepfun-ai/Step-3.5-Flash operation with Q4 quantization.
Your 40GB GPU is 72GB short of the 112GB minimum.
Options: (1) Try Q2 or Q3 quantization for lower VRAM requirements, (2) Consider cloud GPU rental, (3) Upgrade to a GPU with at least 16GB VRAM.
| Quantization | VRAM needed | VRAM available | Estimated speed | Verdict |
|---|---|---|---|---|
| Q4 | 112GB | 40GB | 27.48 tok/s | ❌ Not recommended |
| Q8 | 223GB | 40GB | 19.98 tok/s | ❌ Not recommended |
| FP16 | 446GB | 40GB | 10.33 tok/s | ❌ Not recommended |
