## What's New

* [2025-06-05] 🚀🚀🚀 We have open-sourced **MiniCPM4-Survey**, a model built upon MiniCPM4-8B that is capable of generating trustworthy, long-form survey papers while maintaining competitive performance relative to significantly larger models.

## MiniCPM4 Series
MiniCPM4 series are highly efficient large language models (LLMs) designed explicitly for end-side devices, which achieves this efficiency through systematic innovation in four key dimensions: model architecture, training data, training algorithms, and inference systems.
- [MiniCPM4-8B](https://huggingface.co/openbmb/MiniCPM4-8B): The flagship of MiniCPM4, with 8B parameters, trained on 8T tokens.
- [MiniCPM4-0.5B](https://huggingface.co/openbmb/MiniCPM4-0.5B): The small version of MiniCPM4, with 0.5B parameters, trained on 1T tokens.
- [MiniCPM4-8B-Eagle-FRSpec](https://huggingface.co/openbmb/MiniCPM4-8B-Eagle-FRSpec): Eagle head for FRSpec, accelerating speculative inference for MiniCPM4-8B.
- [MiniCPM4-8B-Eagle-FRSpec-QAT-cpmcu](https://huggingface.co/openbmb/MiniCPM4-8B-Eagle-FRSpec-QAT-cpmcu): Eagle head trained with QAT for FRSpec, efficiently integrate speculation and quantization to achieve ultra acceleration for MiniCPM4-8B.
- [MiniCPM4-8B-Eagle-vLLM](https://huggingface.co/openbmb/MiniCPM4-8B-Eagle-vLLM): Eagle head in vLLM format, accelerating speculative inference for MiniCPM4-8B.
- [MiniCPM4-8B-marlin-Eagle-vLLM](https://huggingface.co/openbmb/MiniCPM4-8B-marlin-Eagle-vLLM): Quantized Eagle head for vLLM format, accelerating speculative inference for MiniCPM4-8B.
- [BitCPM4-0.5B](https://huggingface.co/openbmb/BitCPM4-0.5B): Extreme ternary quantization applied to MiniCPM4-0.5B compresses model parameters into ternary values, achieving a 90% reduction in bit width.
- [BitCPM4-1B](https://huggingface.co/openbmb/BitCPM4-1B): Extreme ternary quantization applied to MiniCPM3-1B compresses model parameters into ternary values, achieving a 90% reduction in bit width.
- [MiniCPM4-Survey](https://huggingface.co/openbmb/MiniCPM4-Survey): Based on MiniCPM4-8B, accepts users' quiries as input and autonomously generate trustworthy, long-form survey papers. (**<-- you are here**)
- [MiniCPM4-MCP](https://huggingface.co/openbmb/MiniCPM4-MCP): Based on MiniCPM4-8B, accepts users' queries and available MCP tools as input and autonomously calls relevant MCP tools to satisfy users' requirements.

## Overview

**MiniCPM4-Survey** is an open-source LLM agent model jointly developed by [THUNLP](https://nlp.csai.tsinghua.edu.cn), Renmin University of China and [ModelBest](https://modelbest.cn/en). Built on [MiniCPM4](https://github.com/OpenBMB/MiniCPM4) with 8 billion parameters, it accepts users' quiries as input and autonomously generate trustworthy, long-form survey papers.

Key features include:

- **Plan-Retrieve-Write Survey Generation Framework** — We propose a multi-agent generation framework, which operates through three core stages: planning (defining the overall structure of the survey), retrieval (generating appropriate retrieval keywords), and writing (synthesizing the retrieved information to generate coherent section-level content).

- **High-Quality Dataset Construction** — We gather and process lots of expert-written survey papers to construct a high-quality training dataset. Meanwhile, we collect a large number of research papers to build a retrieval database.

- **Multi-Aspect Reward Design** — We carefully design a reward system with three aspects (structure, content, and citations) to evaluate the quality of the surveys, which is used as the reward function in the RL training stage.

- **Multi-Step RL Training Strategy** — We propose a *Context Manager* to ensure retention of essential information while facilitating efficient reasoning, and we construct *Parallel Environment* to maintain efficient RL training cycles.  


## Quick Start

### Download the model

Download [MiniCPM4-Survey](https://huggingface.co/openbmb/MiniCPM4-Survey) from Hugging Face and place it in `model/MiniCPM4-Survey`.
We recommend using [MiniCPM-Embedding-Light](https://huggingface.co/openbmb/MiniCPM-Embedding-Light) as the embedding model, which can be downloaded from Hugging Face and placed in `model/MiniCPM-Embedding-Light`.
### Perpare the environment

You can download the [paper data](https://www.kaggle.com/datasets/Cornell-University/arxiv) from Kaggle, then extract it. You can run `python dataset_process.py` to process the data and generate the retrieval database. Then you can run `python build_index.py` to build the retrieval database.

```
cd ./code
curl -L -o ~/Downloads/arxiv.zip\
   https://www.kaggle.com/api/v1/datasets/download/Cornell-University/arxiv
unzip ~/Downloads/arxiv.zip -d .
mkdir data
python ./src/preprocess/dataset_process.py
mkdir index
python ./src/preprocess/build_index.py
```

### Model Inference

You can run the following command to build the retrieval environment and start the inference:

```bash
cd ./code
python ./src/retriever.py
bash ./scripts/run.sh
```

If you want to run with the frontend, you can run the following command:

```bash
cd ./code
python ./src/retriever.py
bash ./scripts/run_with_frontend.sh
cd frontend/minicpm4-survey
npm install
npm run dev
```

Then you can visit `http://localhost:5173` in your browser to use the model.

## 概览

MiniCPM4-Survey是由[THUNLP](https://nlp.csai.tsinghua.edu.cn)、中国人民大学和[ModelBest](https://modelbest.cn)联合开发的开源大语言模型智能体。它基于[MiniCPM4](https://github.com/OpenBMB/MiniCPM4) 80亿参数基座模型，接受用户质量作为输入，自主生成可信的长篇综述论文。

主要特性包括：
