| ## Introduction
|
| MiniCPM 4 is an extremely efficient edge-side large model that has undergone efficient optimization across four dimensions: model architecture, learning algorithms, training data, and inference systems, achieving ultimate efficiency improvements.
|
|
|
| - 🏗️ **Efficient Model Architecture:**
|
| - InfLLM v2 -- Trainable Sparse Attention Mechanism: Adopts a trainable sparse attention mechanism architecture where each token only needs to compute relevance with less than 5% of tokens in 128K long text processing, significantly reducing computational overhead for long texts
|
|
|
| - 🧠 **Efficient Learning Algorithms:**
|
| - Model Wind Tunnel 2.0 -- Efficient Predictable Scaling: Introduces scaling prediction methods for performance of downstream tasks, enabling more precise model training configuration search
|
| - BitCPM -- Ultimate Ternary Quantization: Compresses model parameter bit-width to 3 values, achieving 90% extreme model bit-width reduction
|
| - Efficient Training Engineering Optimization: Adopts FP8 low-precision computing technology combined with Multi-token Prediction training strategy
|
|
|
| - 📚 **High-Quality Training Data:**
|
| - UltraClean -- High-quality Pre-training Data Filtering and Generation: Builds iterative data cleaning strategies based on efficient data verification, open-sourcing high-quality Chinese and English pre-training dataset [UltraFinweb](https://huggingface.co/datasets/openbmb/Ultra-FineWeb)
|
| - UltraChat v2 -- High-quality Supervised Fine-tuning Data Generation: Constructs large-scale high-quality supervised fine-tuning datasets covering multiple dimensions including knowledge-intensive data, reasoning-intensive data, instruction-following data, long text understanding data, and tool calling data
|
|
|
| - ⚡ **Efficient Inference System:**
|
| - FRSpec -- Lightweight Speculative Sampling: Achieves draft model acceleration through vocabulary pruning of draft model
|
| - ArkInfer -- Cross-platform Deployment System: Supports efficient deployment across multiple backend environments, providing flexible cross-platform adaptation capabilities
|
|
|
| ## Usage
|
| ### Inference with Transformers
|
|
|
| ### Inference with [vLLM](https://github.com/vllm-project/vllm)
|
|
|
| ## Evaluation Results
|
| On two typical end-side chips, Jetson AGX Orin and RTX 4090, MiniCPM4 demonstrates significantly faster processing speed compared to similar-size models in long text processing tasks. As text length increases, MiniCPM4's efficiency advantage becomes more pronounced. On the Jetson AGX Orin platform, compared to Qwen3-8B, MiniCPM4 achieves approximately 7x decoding speed improvement.
|
|
|
| 
|
|
|
| #### Comprehensive Evaluation
|
| MiniCPM4 launches end-side versions with 8B and 0.5B parameter scales, both achieving best-in-class performance in their respective categories.
|
|
|
| 
|
|
|
| #### Long Text Evaluation
|
| MiniCPM4 is pre-trained on 32K long texts and achieves length extension through YaRN technology. In the 128K long text needle-in-a-haystack task, MiniCPM4 demonstrates outstanding performance.

| ## Statement
|
| - As a language model, MiniCPM generates content by learning from a vast amount of text.
|
| - However, it does not possess the ability to comprehend or express personal opinions or value judgments.
|
| - Any content generated by MiniCPM does not represent the viewpoints or positions of the model developers.
|
| - Therefore, when using content generated by MiniCPM, users should take full responsibility for evaluating and verifying it on their own.
