AgentCPM-Report: Gemini-2.5-pro-DeepResearch Level Local DeepResearch

This repository contains AgentCPM-Report, an 8B-parameter deep research agent introduced in the paper AgentCPM-Report: Interleaving Drafting and Deepening for Open-Ended Deep Research.

AgentCPM-Report uses a Writing As Reasoning Policy (WARP) to dynamically revise outlines during report generation, alternating between evidence-based drafting and reasoning-driven deepening to produce high-quality, long-form research reports.

News

• [2026-01-20] 🚀🚀🚀 We open-sourced AgentCPM-Report built on MiniCPM4.1-8B, capable of matching top closed-source commercial systems like Gemini-2.5-pro-DeepResearch in report generation.

Overview

AgentCPM-Report is an open-source large language model agent jointly developed by THUNLP, Renmin University of China RUCBM, and ModelBest. It is based on the MiniCPM4.1 8B-parameter base model. It accepts user instructions as input and autonomously generates long-form reports. Key highlights:

• Extreme Performance, Minimal Footprint: Through an average of 40 rounds of deep retrieval and nearly 100 rounds of chain-of-thought reasoning, it achieves comprehensive information mining and restructuring, enabling edge-side models to produce logically rigorous, deeply insightful long-form articles with tens of thousands of words. With just 8 billion parameters, it delivers performance on par with top-tier closed-source systems in deep research tasks.
• Physical Isolation, Local Security: Specifically designed for high-privacy scenarios, it supports fully offline and agile local deployment, completely eliminating the risk of cloud data leaks. Leveraging our UltraRAG framework, it efficiently mounts and understands your local private knowledge base, securely transforming core confidential data into highly valuable professional decision-making reports without ever leaving its domain.

Quick Start

Docker Deployment

You can watch our demo video here Tutorial 🔗

We provide a minimal one-click docker-compose deployment integrated with UltraRAG, including the RAG framework UltraRAG2.0, the model inference framework vllm, and the vector database milvus. If you want CPU inference, we also provide a llama.cpp-based version for gguf models—just switch docker-compose.yml to docker-compose.cpu.yml.

git clone git@github.com:OpenBMB/UltraRAG.git
cd UltraRAG
git checkout agentcpm-report-demo
cd agentcpm-report-demo
cp env.example .env
docker-compose -f docker-compose.yml up -d --build
docker-compose -f docker-compose.yml logs -f ultrarag-ui

The first startup pulls images, downloads the model, and configures the environment, which takes about 30 minutes. Then open http://localhost:5050. If you can see the UI, your deployment is successful. Follow the UI instructions to upload local files, chunk them, and build indexes; then in the Chat section, select AgentCPM-Report in the pipeline to start your workflow.

(Optional) You can import Wiki2024 as the writing database.

You can read more tutorials about AgentCPM-Report in the documentation.

Evaluation

Our evaluation datasets include DeepResearch Bench, DeepConsult, and DeepResearch Gym. The writing-time knowledge base includes about 2.7 million Arxiv papers and about 200,000 internal webpage summaries.

Acknowledgements

This project would not be possible without the support and contributions of the open-source community. During development, we referred to and used multiple excellent open-source frameworks, models, and data resources, including verl, UltraRAG, MiniCPM4.1, and SurveyGo.
