Hardware Requirements
Estimated requirements (calculated by Local Model Watch) — 2.5B parameters
| Your VRAM | Quantization | File size | Est. memory needed |
|---|---|---|---|
| 4GB (laptop iGPU / phone class) | Q8_0 | 2.5GB | 3.0GB |
| 8GB (RTX 4060 / 3060 Ti, etc.) | F16 | 4.7GB | 5.6GB |
Memory estimates add a 20% runtime overhead (KV cache, etc.) to the actual size of the distributed files. Actual usage varies with context length, batch size and inference engine. These figures are computed by this site from file sizes, not published by the model’s authors. File sizes are measured from the converted build openbmb/MiniCPM5-2B-GGUF. Compare with other models in our VRAM quick reference. What the quantization names mean: glossary.
