MiniCPM V 4 5 — Hardware Requirements & GPU Compatibility
VisionFunctions
MiniCPM-V 4.5 is an 8.7-billion-parameter vision-language model from OpenBMB, combining a Qwen3-8B language backbone with a SigLIP2 vision encoder. It is designed to run efficiently on modest hardware, including phones and laptops, while handling image, multi-image, and video understanding alongside text chat; a unified resampler compresses video frames heavily so longer clips don't demand proportionally more compute. At under 9 billion parameters, it fits comfortably on a single mainstream consumer GPU once quantized. It supports a 40,960 token context window, sufficient for long documents or multi-turn multimodal conversations. It is released under the Apache 2.0 license, allowing unrestricted commercial and research use. Published in August 2025, it distinguishes itself with a switchable "fast" and "deep" thinking mode, trading response speed for more deliberate reasoning on harder problems.

Frequently Asked Questions
How much VRAM does MiniCPM V 4 5 need?
MiniCPM V 4 5 requires 5.8 GB of VRAM at Q4_K_M, or 18.0 GB at BF16. Full 41K context adds up to 5.7 GB (11.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.7B × 4.8 bits ÷ 8 = 5.2 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 6.4 GB (at full 41K context)
VRAM usage by quantization
What's the best quantization for MiniCPM V 4 5?
For MiniCPM V 4 5, Q4_K_M (5.8 GB) offers the best balance of quality and VRAM usage. Q5_0 (6.0 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 4.3 GB.
