-## MiniCPM-V 4.7
-
-### Prepare models and code
-
-Download [MiniCPM-V-4.7](https://huggingface.co/openbmb/MiniCPM-V-4.7) PyTorch model from huggingface to "MiniCPM-V-4.7" folder.
-
-The model must be the standard `transformers` checkpoint (no `trust_remote_code` for the text and vision graph used here); the architecture in `config.json` is `MiniCPMV4_7ForConditionalGeneration` with a `qwen3_5_text` (or `qwen3_5_moe_text`) text model and a SigLIP-based vision tower plus a window-attention `vit_merger`, same as MiniCPM-V 4.6.
-
-If the checkpoint ships no MTP weights, pass `--no-mtp` to skip the nextn layers.
-
-### Build llama.cpp
-
-If there are differences in usage, please refer to the official build [documentation](https://github.com/ggml-org/llama.cpp/blob/master/docs/build.md)
-
-Clone llama.cpp:
-```bash
-git clone https://github.com/ggml-org/llama.cpp
-cd llama.cpp
-```
-
-Build llama.cpp using `CMake`:
-```bash
-cmake -B build
-cmake --build build --config Release
-```
-
-
-### Usage of MiniCPM-V 4.7
-
-MiniCPM-V 4.7 is converted directly through `convert_hf_to_gguf.py`. The same script is invoked twice on the original Hugging Face directory: once to produce the language-model GGUF and once with `--mmproj` to produce the multimodal projector GGUF.
-
-```bash
-# language model
-python ./convert_hf_to_gguf.py ../MiniCPM-V-4.7 --outfile ../MiniCPM-V-4.7/ggml-model-f16.gguf --no-mtp
-
-# multimodal projector (vision tower + window-attention vit_merger + DownsampleMLP merger)
-python ./convert_hf_to_gguf.py ../MiniCPM-V-4.7 --mmproj --outfile ../MiniCPM-V-4.7/mmproj-model-f16.gguf

To keep 4x more visual tokens, copy the model dir and set `"downsample_mode": "4x"` in the copy's `preprocessor_config.json` before running the `--mmproj` conversion; the loader reads `clip.vision.projector.scale_factor` to pick the graph.
