MiniCPM-o Project Description

What is the project about?

MiniCPM-o is a series of end-side multimodal large language models (MLLMs) capable of processing images, video, text, and audio inputs, and producing high-quality text and speech outputs. It's designed for efficient deployment and strong performance, particularly on mobile devices.

What problem does it solve?

Limited multimodal capabilities on end-side devices: Provides powerful multimodal understanding and generation (vision, speech, text) that can run efficiently on devices like phones and tablets, rather than requiring cloud servers.
High computational cost of existing MLLMs: Offers a smaller model size (8B parameters) and superior token density, leading to faster inference, lower latency, reduced memory usage, and lower power consumption.
Lack of open-source models matching proprietary performance: Aims to achieve performance comparable to or surpassing proprietary models like GPT-4o, Gemini 1.5 Pro, and Claude 3.5 Sonnet in various multimodal tasks.
Lack of real-time speech conversation and multimodal live streaming capabilities.

What are the features of the project?

Multimodal Input/Output: Handles images, video, text, and audio as input; generates text and speech.
Strong Visual Capability: Excellent performance on single-image, multi-image, and video understanding benchmarks.
State-of-the-art Speech Capability: Supports bilingual real-time speech conversation with configurable voices, emotion/speed/style control, voice cloning, and role-play.
Multimodal Live Streaming: Processes continuous video and audio streams, enabling real-time interaction.
Strong OCR: High accuracy in optical character recognition.
Trustworthy Behavior: Reduced hallucination rates and multilingual support.
Efficient Deployment: Optimized for end-side devices, with support for quantization (int4, GGUF) and efficient inference tools (llama.cpp, ollama, vLLM).
Easy Usage: Provides various ways to use the model, including local demos, web demos, and fine-tuning options.
End-to-end Omni-modal Architecture: Omni-modality encoders/decoders are connected and trained in an end-to-end fashion.
Omni-modal Live Streaming Mechanism: A time-division multiplexing (TDM) mechanism for omni-modality streaming processing.
Configurable Speech Modeling Design: A multimodal system prompt, including traditional text system prompt, and a new audio system prompt to determine the assistant voice.
