A GPT-4V Level MLLM for Single Image, Multi Image and Video on Your Phone

MiniCPM-V 4.0

MiniCPM-V 4.0 is the latest efficient model in the MiniCPM-V series. The model is built based on SigLIP2-400M and MiniCPM4-3B with a total of 4.1B parameters. It inherits the strong single-image, multi-image and video understanding performance of MiniCPM-V 2.6 with largely improved efficiency. Notable features of MiniCPM-V 4.0 include:

🔥 Leading Visual Capability. With only 4.1B parameters, MiniCPM-V 4.0 achieves an average score of 69.0 on OpenCompass, a comprehensive evaluation of 8 popular benchmarks, outperforming GPT-4.1-mini-20250414, MiniCPM-V 2.6 (8.1B params, OpenCompass 65.2) and Qwen2.5-VL-3B-Instruct (3.8B params, OpenCompass 64.5). It also shows good performance in multi-image understanding and video understanding.
🚀 Superior Efficiency. Designed for on-device deployment, MiniCPM-V 4.0 runs smoothly on end devices. For example, it devlivers less than 2s first token delay and more than 17 token/s decoding on iPhone 16 Pro Max, without heating problems. It also shows superior throughput under concurrent requests.
💫 Easy Usage. MiniCPM-V 4.0 can be easily used in various ways including llama.cpp, Ollama, vLLM, SGLang, LLaMA-Factory and local web demo etc. We also open-source iOS App that can run on iPhone and iPad. Get started easily with our well-structured Cookbook, featuring detailed instructions and practical examples.

Usage

from PIL import Image
import torch
from transformers import AutoModel, AutoTokenizer

model_path = 'openbmb/MiniCPM-V-4'
model = AutoModel.from_pretrained(model_path, trust_remote_code=True,
                                  # sdpa or flash_attention_2, no eager
                                  attn_implementation='sdpa', torch_dtype=torch.bfloat16)
model = model.eval().cuda()
tokenizer = AutoTokenizer.from_pretrained(
    model_path, trust_remote_code=True)



image = Image.open('./assets/single.png').convert('RGB')

# First round chat 
question = "What is the landform in the picture?"
msgs = [{'role': 'user', 'content': [image, question]}]

answer = model.chat(
    msgs=msgs,
    image=image,
    tokenizer=tokenizer
)
print(answer)


# Second round chat, pass history context of multi-turn conversation
msgs.append({"role": "assistant", "content": [answer]})
msgs.append({"role": "user", "content": [
            "What should I pay attention to when traveling here?"]})

answer = model.chat(
    msgs=msgs,
    image=None,
    tokenizer=tokenizer
)
print(answer)
