Frequently Asked Questions
- How much VRAM does MiniCPM5 2B Base need?
MiniCPM5 2B Base requires 1.9 GB of VRAM at Q4_K_M, or 5.4 GB at BF16. Full 524K context adds up to 22.5 GB (24.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 2.5B × 4.8 bits ÷ 8 = 1.5 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 22.9 GB (at full 524K context)
VRAM usage by quantization
Q4_K_M1.9 GBQ4_K_M + full context24.4 GB- What's the best quantization for MiniCPM5 2B Base?
For MiniCPM5 2B Base, Q4_K_M (1.9 GB) offers the best balance of quality and VRAM usage. Q5_K_M (2.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.5 GB.

- Can I run MiniCPM5 2B Base on a Mac?
MiniCPM5 2B Base requires at least 1.5 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run MiniCPM5 2B Base locally?
Yes — MiniCPM5 2B Base can run locally on consumer hardware. At Q4_K_M quantization it needs 1.9 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is MiniCPM5 2B Base?
At Q4_K_M, MiniCPM5 2B Base can reach ~2526 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~345 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 1.9 × 0.65 = ~2737 tok/s
Estimated speed at Q4_K_M (1.9 GB)
~2737 tok/s~345 tok/s~2737 tok/s~2526 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of MiniCPM5 2B Base?
At Q4_K_M, the download is about 1.51 GB. The full-precision BF16 version is 5.03 GB. The smallest option (Q2_K) is 1.07 GB.
- Which GPUs can run MiniCPM5 2B Base?
