MiniCPM-V4.0: A New Era for Mobile AI

The OpenBMB research team has officially open-sourced MiniCPM-V4.0, a breakthrough multimodal large language model specifically optimized for mobile devices. Dubbed "GPT-4V on a phone," this lightweight yet powerful system promises to revolutionize how we interact with AI through smartphones and edge devices.

Technical Architecture and Performance

Built upon SigLIP2-400M and MiniCPM4-3B architectures, the model contains only 4.1 billion parameters while delivering exceptional capabilities in:

• Image and multi-image comprehension
• Video content analysis
• Complex visual relationship understanding

Benchmark tests reveal impressive results, with MiniCPM-V4.0 achieving an average score of 69.0 across eight OpenCompass evaluations - surpassing competitors like GPT-4.1-mini and Qwen2.5-VL-3B.

Mobile Optimization Breakthroughs

The engineering team prioritized real-world usability:

• <2 second first-response latency on iPhone 16 Pro Max
• Decoding speeds exceeding 17 tokens/second
• Advanced thermal management for sustained performance
• High-concurrency support for practical applications

"We've eliminated the traditional trade-off between model size and capability," noted an OpenBMB spokesperson. "This makes professional-grade AI accessible in everyone's pocket."
