Technical principles of MiniCPM 3.0
- LLMxMapReduce technology: A long text framing processing technology that supports the model in processing text beyond its original memory limit. By splitting long text into small blocks (or "frames"), the model can process the entire text block by block, achieving processing of "unlimited" long text.
- Quantization technology: MiniCPM 3.0 adopts quantization technology to reduce the model's memory requirement to 2GB, allowing the model to run on resource-constrained edge devices without sacrificing too much performance.
- Function Calling: A technology that enables the model to understand and execute user instructions, involving calling external applications or services. MiniCPM 3.0's performance in this area is close to GPT-4o, showing its potential to execute complex tasks on edge devices.
- RAG（Retrieval-Augmented Generation）: A technology combining retrieval (Retrieval) and generation (Generation), where the model can retrieve relevant information from large amounts of data and use it to generate more accurate and richer answers. MiniCPM 3.0's RAG trio includes:
- MiniCPM-Embedding: A model used for retrieval tasks, capable of efficiently finding relevant information from large-scale datasets.
- MiniCPM-Reranker: Reranks the retrieved candidate answers to improve the relevance and accuracy of the answers.
- LoRA plugin: A generation model optimized for RAG scenarios, capable of using retrieved information to generate coherent and accurate text.
- Model fine-tuning: MiniCPM 3.0 supports fine-tuning on specific tasks to adapt to different application scenarios and requirements. This involves further training the model on specific datasets to improve its performance on specific tasks.
- Efficient Training Methods: ModelBest has adopted scientific training methods and data quality control to improve the model's "knowledge density", that is, the ratio of the model's capability to its number of parameters. This helps improve its performance while keeping the model size unchanged.
