- [2025.01.14] We open source MiniCPM-o 2.6, with significant performance improvement over MiniCPM-V 2.6, and support real-time speech-to-speech conversation and multimodal live streaming. Try it now.
MiniCPM-V 2.6 Introduction
MiniCPM-V 2.6 is the latest and most capable model in the MiniCPM-V series. Built on SigLip-400M and Qwen2-7B with a total of 8B parameters, it outperforms MiniCPM-Llama3-V 2.5 and introduces new features for multi-image and video understanding.
⨠Features
Leading Performance
MiniCPM-V 2.6 achieves an average score of 65.2 on the latest version of OpenCompass, a comprehensive evaluation over 8 popular benchmarks. With only 8B parameters, it surpasses widely used proprietary models like GPT-4o mini, GPT-4V, Gemini 1.5 Pro, and Claude 3.5 Sonnet for single image understanding.
Multi Image Understanding and In-context Learning
MiniCPM-V 2.6 can perform conversation and reasoning over multiple images. It achieves state-of-the-art performance on popular multi-image benchmarks such as Mantis-Eval, BLINK, Mathverse mv and Sciverse mv, and also shows promising in-context learning capability.
Video Understanding
MiniCPM-V 2.6 can accept video inputs, performing conversation and providing dense captions for spatial-temporal information. It outperforms GPT-4V, Claude 3.5 Sonnet and LLaVA-NeXT-Video-34B on Video-MME with/without subtitles.
Strong OCR Capability and Others
MiniCPM-V 2.6 can process images with any aspect ratio and up to 1.8 million pixels (e.g., 1344x1344). It achieves state-of-the-art performance on OCRBench, surpassing proprietary models such as GPT-4o, GPT-4V, and Gemini 1.5 Pro. Based on the latest RLAIF-V and VisCPM techniques, it features trustworthy behaviors, with significantly lower hallucination rates than GPT-4o and GPT-4V on Object HalBench, and supports multilingual capabilities on English, Chinese, German, French, Italian, Korean, etc.
Superior Efficiency
In addition to its friendly size, MiniCPM-V 2.6 also shows state-of-the-art token density (i.e., number of pixels encoded into each visual token). It produces only 640 tokens when processing a 1.8M pixel image, which is 75% fewer than most models. This directly improves the inference speed, first-token latency, memory usage, and power consumption. As a result, MiniCPM-V 2.6 can efficiently support real-time video understanding on end-side devices such as iPad.
Easy Usage
MiniCPM-V 2.6 can be easily used in various ways:
- llama.cpp and ollama support for efficient CPU inference on local devices.
- int4 and GGUF format quantized models in 16 sizes.
- vLLM support for high-throughput and memory-efficient inference.
- Fine-tuning on new domains and tasks.
- Quick local WebUI demo setup with Gradio.
- Online web demo.
Evaluation
Single image results on OpenCompass, MME, MMVet, OCRBench, MMMU, MathVista, MMB, AI2D, TextVQA, DocVQA, HallusionBench, Object HalBench:
* We evaluate this benchmark using chain-of-thought prompting.
+ Token Density: number of pixels encoded into each visual token at maximum resolution, i.e., # pixels at maximum resolution / # visual tokens.
Note: For proprietary models, we calculate token density based on the image encoding charging strategy defined in the official API documentation, which provides an upper-bound estimation.
Multi-image results on Mantis Eval, BLINK Val, Mathverse mv, Sciverse mv, MIRB:
* We evaluate the officially released checkpoint by ourselves.
Video results on Video-MME and Video-ChatGPT:
Click to view few-shot results on TextVQA, VizWiz, VQAv2, OK-VQA.
* denotes zero image shot and two additional text shots following Flamingo.
+ We evaluate the pretraining ckpt without SFT.
