Frequently Asked Questions
How much VRAM does MiniCPM5 2B DSpark need?
MiniCPM5 2B DSpark requires 0.5 GB of VRAM at Q4_K_M, or 1.0 GB at BF16. Full 131K context adds up to 0.7 GB (1.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 324M × 4.8 bits ÷ 8 = 0.2 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 1 GB (at full 131K context)
VRAM usage by quantization
What's the best quantization for MiniCPM5 2B DSpark?
For MiniCPM5 2B DSpark, Q4_K_M (0.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.5 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run MiniCPM5 2B DSpark on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run MiniCPM5 2B DSpark. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.5 GB of usable unified memory (RAM minus macOS overhead).
Can I run MiniCPM5 2B DSpark locally?
Yes — MiniCPM5 2B DSpark can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is MiniCPM5 2B DSpark?
At Q4_K_M, MiniCPM5 2B DSpark can reach ~9600 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1310 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 ÷ 0.5 × 0.65 = ~10400 tok/s
Estimated speed at Q4_K_M (0.5 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of MiniCPM5 2B DSpark?
At Q4_K_M, the download is about 0.19 GB. The full-precision BF16 version is 0.65 GB. The smallest option (Q2_K) is 0.14 GB.
