Introducing MiniCPM 4.0: Wallface AI's Edge Model Boosts Performance by 220x

Introduction to MiniCPM 4.0

On June 6, 2025, Mianbi Intelligent unveiled its latest innovation, the MiniCPM 4.0 series, which has been hailed as "the most imaginative small powerhouse ever." This new series not only marks a significant leap in edge performance but also sets a new benchmark in technological innovation.

Key Features of MiniCPM 4.0

The MiniCPM 4.0 series comprises two remarkable models:

1. 8B Lightning Sparse Version: This model introduces an innovative sparse architecture that promises high efficiency.
2. 0.5B Agile Version: Dubbed the "strongest small powerhouse," this lightweight model is designed for flexibility and performance.

Both models exhibit exceptional capabilities in speed, efficiency, performance, and practical applications.

Speed Enhancements

The MiniCPM 4.0 series achieves remarkable speed improvements:

• Extreme Conditions: Up to ### 220 times faster.
• Standard Conditions: A consistent ### 5 times speed increase.

This impressive acceleration is attributed to a system-level sparse innovation that layers multiple enhancements. The implementation of an efficient dual-frequency switching technology allows the model to automatically toggle between sparse and dense attention mechanisms based on text length. This ensures rapid and efficient processing of long texts while significantly reducing edge storage requirements. Compared to similar models like Qwen3-8B, MiniCPM 4.0 requires only ### one-fourth of the cache storage space.

Efficiency Innovations

MiniCPM 4.0 introduces the industry's first fully open-source system-level context sparsification innovation. With an impressive ### 5% sparsity rate, it achieves extreme acceleration. The model integrates proprietary technologies that optimize performance across various layers:

• Architecture Layer
• System Layer
• Inference Layer
• Data Layer

This comprehensive optimization enables effective system-level hardware and software sparsification.

Performance Metrics

Continuing the tradition of "small but mighty," the MiniCPM 4.0 models deliver outstanding performance:

• The ### 0.5B version achieves double the performance with only ### 2.7% of the training overhead.
• The ### 8B sparse version matches and surpasses competitors like Qwen3 and Gemma312B with a training overhead of just ### 22%.

These metrics solidify MiniCPM 4.0's leading position in the edge computing domain.

Practical Applications

The MiniCPM 4.0 series demonstrates formidable capabilities in real-world applications. Utilizing the proprietary ### CPM.cu rapid edge inference framework, it combines innovations in speculative sampling, model compression, quantization, and edge deployment frameworks. This results in a ### 90% reduction in model size while dramatically enhancing speed, ensuring a seamless inference experience from inception to deployment.

Currently, the MiniCPM 4.0 models are compatible with major chipsets, including:

• Intel
• Qualcomm
• MTK
• Huawei Ascend

Additionally, they have been successfully deployed across various open-source frameworks, further expanding their application potential.
