minicpm5-deploy-llama-cpp

Deploy MiniCPM5-1B and MiniCPM5-2B with llama.cpp

CPU / edge / consumer-GPU deployment via the released GGUF artifacts. The artifacts work directly with vanilla llama.cpp and every downstream runtime (Ollama / LM Studio / llama-cpp-python).

Required input

Steps

1. Install llama.cpp

# macOS
brew install llama.cpp

# Linux / cross-platform: pre-built binary
curl -fsSL https://github.com/ggerganov/llama.cpp/releases/latest/download/llama-cli-linux.tar.gz | tar -xz
# OR build from source:
git clone --depth=1 https://github.com/ggerganov/llama.cpp.git && cd llama.cpp
mkdir build && cd build
cmake .. -DGGML_CUDA=ON -DCMAKE_BUILD_TYPE=Release    # CPU-only: omit GGML_CUDA=ON
cmake --build . --config Release -j $(nproc) --target llama-cli llama-server

2. Download the GGUF

mkdir -p ~/minicpm5 && cd ~/minicpm5
huggingface-cli download ${GGUF_REPO} MiniCPM5-2B-${QUANT}.gguf --local-dir .

3a. Interactive chat (CLI)

llama-cli -m MiniCPM5-2B-${QUANT}.gguf \
    -n 2048 --temp 1.0 --top-p 0.95 --min-p 0.0 -ngl ${NGL} -c ${CTX}

3b. OpenAI-compatible HTTP server

llama-server -m MiniCPM5-2B-${QUANT}.gguf \
    --port 8080 -ngl ${NGL} -c ${CTX} --jinja

4. Validate

curl http://localhost:8080/v1/chat/completions \
    -H "Content-Type: application/json" \
    -d '{
        "model": "MiniCPM5-2B",
        "messages": [{"role":"user","content":"1+1=?"}],
        "temperature": 1.0, "top_p": 0.95, "min_p": 0.0, "max_tokens": 64
    }'

Expected: "2" in the reply.

In llama.cpp, the default min_p=0.05 can lead to repetitive output: it filters out tokens whose probability is below 5% of the highest-probability token, potentially discarding the exact tokens needed to break out of a repetition loop. To prevent this, we set min_p=0.0.
