MiniCPM-V 4.6 - Ollama

Note

MiniCPM-V 4.6 is officially supported by Ollama starting from v0.30. Please make sure your Ollama version is 0.30 or newer; older releases do not include the model and will fail to load it.

1. Install Ollama

macOS: download from https://ollama.com/download/Ollama.dmg.
Windows: download from https://ollama.com/download/OllamaSetup.exe.
Linux: curl -fsSL https://ollama.com/install.sh | sh, or follow the Linux install guide.
Docker: official Ollama Docker image ollama/ollama is on Docker Hub.

Verify your version is at least 0.30:

ollama --version

2. Quick Start

Pull and run the official OpenBMB model from the Ollama registry (https://ollama.com/openbmb/minicpm-v4.6):

ollama run openbmb/minicpm-v4.6
# or, for the Thinking variant
ollama run openbmb/minicpm-v4.6-thinking

Command line

Separate the input prompt and the image path with a space:

API

import base64, requests

with open(image_path, 'rb') as image_file:
    encoded_string = base64.b64encode(image_file.read()).decode('utf-8')
    data = {
        "model": "openbmb/minicpm-v4.6",
        "prompt": query,
        "stream": False,
        "images": [encoded_string],  # the list can hold multiple base64-encoded images
    }
    url = "http://localhost:11434/api/generate"
    response = requests.post(url, json=data)

3. Customize model

If you'd like to load a local GGUF (e.g. a custom quantization), follow the steps below.
