MiniCPM: Unveiling the Infinite Potential of End-side Large Language Models

Overview

MiniCPM is an open-source series of end-side large models jointly released by Mianbi Intelligence and the Natural Language Processing Laboratory of Tsinghua University. The main language model, MiniCPM-2B, has only 2.4 billion non-embedding parameters. It has shown comparable or superior performance to several larger models in various benchmarks, especially in Chinese, mathematics, and coding capabilities. MiniCPM can be deployed on mobile devices with efficient inference capabilities and has a low secondary development cost.

Apparent Issues and TODOs

• Hallucination Issues: Due to its scale, the model might produce hallucinatory responses, especially with the DPO model that generates longer replies.
• Lack of Identity Training: The model has not undergone any identity training, which might lead to the output of identity information similar to GPT models.
• Prompt Sensitivity: The model's outputs are highly influenced by prompts, which may result in inconsistent results upon multiple attempts.
• Inaccurate Knowledge Memory: The model's capacity for accurate knowledge recall is limited, and future enhancements are planned using the RAG method.

Recent Development Activities

Recent activities of the development team include updates to the README files, the addition of demo deployment scripts, and fine-tuning scripts. The team members and their contributions are as follows:

• huangyuxiang03: Fixed issues with flash attention and CPU inference, updated README files, and added support for vLLM.
• ShengdingHu (DingDing): Updated README files in both English and Chinese, and provided links to technical blogs and model downloads.
• SUDA-HLT-ywfang (Y.W. Fang): Fixed typos in the demo, updated README files, and replaced text cases with images.
• soulteary (Su Yang): Added features to set torch dtype and change the demo host and port.
• zkh2016 (zhangkaihuo): Updated README files.
• tuantuanzhang (zhang xinrong): Added a replicate URL to the README.
• Achazwl (William): Updated English README and community links.
• SwordFaith (Xiang Long): Added fine-tuning scripts and fixed related issues.
• THUCSTHanxu13 (SillyXu): Updated README files.
• jctime (Chao Jia): Updated README files.

The team has collaborated on updating documentation, refining the model's deployment capabilities, and ensuring the model's performance is well-documented. The pattern of activity suggests a strong focus on improving user experience and accessibility of the model, as well as preparing the model for broader use cases.

Conclusions

The development team is actively working on improving the model's usability and addressing its limitations. The recent commits indicate a collaborative effort in enhancing documentation, deployment, and fine-tuning capabilities. The team's responsiveness to issues and their commitment to open-sourcing their work for academic research and limited commercial use is evident from their recent activities.
