MiniCPM-V-4.7-1B — GGUF

Community GGUF conversions of openbmb/MiniCPM-V-4.7-1B for llama.cpp multimodal inference.

Official OpenBMB GGUFs: openbmb/MiniCPM-V-4.7-1B-gguf.
This repo adds a full low-to-high quant ladder (Q2_K → Q8_0 + F16) with both 16× and 4× vision projectors, converted with a verified current llama.cpp commit.

Quick start

Download one language model + one mmproj, then run:

llama-mtmd-cli \
  -m MiniCPM-V-4_7-1B-Q4_K_M.gguf \
  --mmproj mmproj-model-f16.gguf \
  -c 8192 \
  --image photo.jpg \
  -p "What is in this image?"

Server example:

llama-server \
  -m MiniCPM-V-4_7-1B-Q4_K_M.gguf \
  --mmproj mmproj-model-f16.gguf \
  --port 8080

Vision always needs an mmproj. Pair any LM quant with mmproj-model-f16.gguf (default 16×) or mmproj-model-f16-4x.gguf (finer detail, more vision tokens).

Which quant should I pick?

Goal Use
Best balance (recommended) Q4_K_M
Better quality Q5_K_M or Q6_K
Near-lossless Q8_0
Max fidelity / re-quantize source F16
Low RAM Q3_K_M
Extremely low RAM Q2_K (expect quality loss)

Vision projector (required for images)

File Size Notes
mmproj-model-f16.gguf 1059 MB Default 16× compression
mmproj-model-f16-4x.gguf 859 MB 4× mode (more visual detail)

mmproj files are kept at F16 on purpose; only the language model is quantized.

Intended use

  • Local / on-device multimodal chat with llama.cpp
  • Offline demos and edge experiments where a small VLM is enough

Limitations

  • Not a drop-in replacement for the original BF16 checkpoint for training or exact numeric reproduction
  • Lower-bit quants (Q2_K / Q3_*) can hurt OCR, grounding, and long reasoning
  • Outputs may be inaccurate or biased; keep human review for important decisions
  • Use a recent llama.cpp build that supports MiniCPM-V 4.7
