Version 0.8.0

Version 0.8.0 (2025-06-27)

1、Overview

We are excited to announce the official release of KAG version 0.8. This update focuses on continuously enhancing the consistency, rigor, and accuracy of large model knowledge base-driven reasoning and question-answering. It also introduces several significant new features and capabilities.
First, we have upgraded the capabilities of the KAG knowledge base. We have expanded support for two modes: private domain knowledge bases (including structured and unstructured data) and public domain knowledge bases. This includes the ability to integrate public web data sources such as LBS and WebSearch via the MCP protocol. Additionally, we have improved the management of private domain knowledge base indexing, incorporating multiple foundational index types such as Outline, Summary, KnowledgeUnit, AtomicQuery, Chunk, and Table. This supports developers in customizing indexes and synchronizing them with product interfaces. Users can select the most appropriate index type based on their specific scenarios, achieving a balance between construction costs and business outcomes.
Second, we have optimized the product experience and refined the system integration interfaces. On the product front, we have decoupled the knowledge base from applications. The knowledge base now manages private domain data (both structured and unstructured) and public domain data, while applications can link to multiple knowledge bases. Based on the index types used during knowledge base construction, the system automatically adapts the corresponding retrieval engine to recall data. Both applications and knowledge bases independently manage model dependencies and task scheduling, enhancing flexibility.
In terms of system integration, we have refined the KAG recall and Q&A interfaces, adding support for embedding reasoning and Q&A pages within business applications. We have fully embraced the MCP protocol, enabling seamless integration of KAG reasoning and Q&A into agent workflows (based on the MCP protocol).
Third, KAG has successfully adapted to the KAG-Thinker model. Through optimizations such as broad decomposition and deep solving of complex problems, knowledge boundary determination, and noise-resistant retrieval results, the stability of the KAG framework's reasoning paradigm and the rigor of its reasoning logic have been significantly improved under the guidance of iterative thinking paradigms. Further details on the release and usage of the KAG-Thinker model will be provided in our upcoming announcements.
In addition to the aforementioned framework and product optimizations, we have also enhanced Q&A efficiency and the stability of streaming outputs. This update is based on the Qwen2.5-72B foundation model and has achieved performance alignment across various RAG frameworks and selected KG datasets. The overall benchmark results of this release are illustrated in Figures 1~3, with detailed metrics available in the open_benchmark section.

2、Framework Enhancements

2.1、Configurable Index Management

Index extraction and retrieval are core capabilities of knowledge base applications. KAG v0.8 has upgraded its architecture to support configurable management of index construction and retrieval. Each index type is equipped with its own extractor (Extractor) and retriever (Retriever), managed through the IndexManager.
KAG comes with built-in foundational index types such as KnowledgeUnit (an enhanced version of graph triples), Outline, Summary, Chunk, AtomicQuery, and Table, along with their corresponding extractors and retrievers. During the knowledge base construction phase, the platform invokes the appropriate extractor based on the index types selected by the user to perform index extraction. In the application phase, based on the knowledge bases associated with the application, the platform automatically calls the corresponding retriever to complete the recall of graph/chunk/doc data and integrates with the KAG-Solver pipeline to enable reasoning and question-answering.
Developers can extend the IndexManager to implement or combine custom extractors and retrievers. After packaging KAG with these custom components and replacing the corresponding installation package in the openspg-server image, users can select the custom index types on the product page during knowledge base construction. This enables seamless integration of custom index types with the product.

3、Product and platform optimization

3.1、System Integration

This release offers three methods to integrate KAG into business systems: HttpAPI, MCP Protocol, and Frontend Page Embedding.
The KAG HttpAPI provides two types of interfaces: recall and reasoning & Q&A. Developers can choose to use KAG as a retrieval source or as a complete reasoning and Q&A capability.
The KAG MCP Protocol offers interfaces for reasoning and Q&A, which can be embedded into agent applications like Cursor.
In this release, the reasoning and Q&A functionality has been upgraded to an independent page, allowing developers to embed this page into their business systems.

3.2、User Experience Optimization

This release addresses several community concerns, including response latency, streaming output stability, model configuration management, and task scheduling reliability. We greatly appreciate the community's support and patience with KAG.

4、Future Plans

In upcoming versions, we will continue to focus on enhancing large models' ability to leverage external knowledge bases. Our goal is to achieve bidirectional enhancement and seamless integration between large models and symbolic knowledge, improving the factuality, rigor, and consistency of reasoning and Q&A in professional scenarios. We will also keep releasing updates to push the boundaries of capability and drive adoption in vertical domains.

Version 0.7

Version 0.7 (2025-04-17)

1、Overview

We are very pleased to announce the release of KAG 0.7. This update continues our commitment to increasing the consistency, rigor, and precision of large language models leveraging external knowledge bases, while introducing several important new features.

Firstly, we have completely refactored the framework. The update adds support for both static and iterative task planning modes, along with a more rigorous hierarchical knowledge mechanism during the reasoning phase. Additionally, the new multi-executor extension mechanism and MCP protocol integration enable horizontal scaling of various symbolic solvers (such as math-executor and cypher-executor). These improvements not only help users quickly build knowledge-augmented applications to validate innovative ideas or domain-specific solutions, but also support continuous optimization of KAG Solver's capabilities, thereby further enhancing reasoning rigor in vertical applications.

Secondly, we have comprehensively optimized the product experience: during the reasoning phase, we introduced dual modes "Simple Mode" and "Deep Reasoning" and added support for streaming reasoning output, significantly reducing user wait times. Particularly noteworthy is the introduction of the "Lightweight Construction" mode to better facilitate the large-scale business application of KAG and address the community's most pressing concern about high knowledge construction costs. As shown in the KAG-V0.7LC column of Figure 1, we tested a hybrid approach where a 7B model handles knowledge construction and a 72B model handles knowledge-based question answering. The results on the two_wiki, hotpotqa, and musique benchmarks showed only minor declines of 1.20%, 1.90%, and 3.11%, respectively. However, the token cost（Refer to Aliyun Bailian pricing）for constructing a 100,000-character document was reduced from 4.63￥ to 0.479￥, a 89% reduction, which substantially saves users both time and financial costs. Additionally, we will release a KAG-specific extraction model and a distributed offline batch construction version, continuously compressing model size and improving construction throughput to achieve daily construction capabilities for millions or even tens of millions of documents in a single scenario.

Finally, to better promote business applications, technological advancement, and community exchange for knowledge-augmented LLMs, we have added an open_benchmark directory at the root level of the KAG repository. This directory includes reproduction methods for various datasets to help users replicate and improve KAG's performance across different tasks. Moving forward, we will continue to expand with more vertical scenario task datasets to provide users with richer resources.

Beyond these framework and product optimizations, we've fixed several bugs in both reasoning and construction phases. This update uses Qwen2.5-72B as the base model, completing effect alignment across various RAG frameworks and partial KG datasets. For overall benchmark results, please refer to Figures 1 and 2, with detailed rankings available in the open_benchmark section.

2、Framework Enhancements

2.1、Hybrid Static-Dynamic Task Planning

This release introduces optimizations to the KAG-Solver framework implementation, providing more flexible architectural support for: "Retrieval during reasoning" workflows, Multi-scenario algorithm experimentation, LLM-symbolic engine integration (via MCP protocol).

The framework's Static/Iterative Planner transforms complex problems into directed acyclic graphs (DAGs) of interconnected Executors, enabling step-by-step resolution based on dependency relationships. We've implemented built-in Pipeline support for both Static and Iterative Planners, including a predefined NaiveRAG Pipeline - offering developers customizable solver chaining capabilities while maintaining implementation flexibility.

2.2、Extensible Symbolic Solvers

Leveraging LLM's FunctionCall capability, we have optimized the design of symbolic solvers (Executors) to enable more rational solver matching during complex problem planning. This release includes built-in solvers such as kag_hybrid_executor, math_executor, and cypher_executor, while providing a flexible extension mechanism that allows developers to define custom solvers for personalized requirements.

2.3、Optimized Retrieval/Reasoning Strategies

Using the enhanced KAG-Solver framework, we have rewritten the logic of kag_hybrid_executor to implement a more rigorous knowledge layering mechanism during reasoning. Based on business requirements for knowledge precision and following KAG's knowledge hierarchy definition, the system now sequentially retrieves three knowledge layers: (schema-constrained), (schema-free), and (raw context), subsequently performing reasoning to generate answers.

2.4、MCP Protocol Integration

This KAG release achieves compatibility with the MCP protocol, enabling the incorporation of external data sources and symbolic solvers into the KAG framework via MCP. We have included a baidu_map_mcp example in the example directory for developers' reference.

3、OpenBenchmark

To better facilitate academic exchange and accelerate the adoption and technological advancement of large language models with external knowledge bases in enterprise settings, KAG has released more detailed benchmark reproduction steps in this version, along with open-sourcing all code and data. This will enable developers and researchers to easily reproduce and align results across various datasets.

For more accurate quantification of reasoning performance, we have adopted multiple evaluation metrics, including EM (Exact Match), F1, and LLM_Accuracy. In addition to existing datasets such as TwoWiki, Musique, and HotpotQA, this update introduces the OpenKG OneEval knowledge graph QA dataset (including AffairQA and PRQA) to evaluate the capabilities of both the cypher_executor and KAG's default framework.

Building benchmarks is a time-consuming and complex endeavor. In future work, we will continue to expand benchmark datasets and provide domain-specific solutions to further enhance the accuracy, rigor, and consistency of large models in leveraging external knowledge. We warmly invite community members to collaborate with us in advancing the KAG framework's capabilities and real-world applications across diverse tasks.

Version 0.5

Version 0.5 (2024-10-25)

retrieval Augmentation Generation (RAG) technology promotes the integration of domain applications with large models. However, RAG has problems such as a large gap between vector similarity and knowledge reasoning correlation, and insensitivity to knowledge logic (such as numerical values, time relationships, expert rules, etc.), which hinder the implementation of professional knowledge services. On October 25, OpenSPG released version V0.5, officially releasing the professional domain knowledge Service Framework for knowledge enhancement generation (KAG) .

Highlights of the Release Version:

1. KAG: Knowledge Augmented Generation

KAG aims to make full use of the advantages of Knowledge Graph and vector retrieval, and bi-directionally enhance large language models and knowledge graphs through four aspects to solve RAG challenges
(1) LLM-friendly semantic knowledge management
(2) Mutual indexing between the knowledge map and the original snippet.
(3) Logical symbol-guided hybrid inference engine
(4) Knowledge alignment based on semantic reasoning
KAG is significantly better than NaiveRAG, HippoRAG and other methods in multi-hop question and answer tasks. The F1 score on hotpotQA is relatively improved by 19.6, and the F1 score on 2wiki is relatively improved by 33.5

2. Knowledge base management

OpenSPG also provides a user-friendly product interface for KAG, allowing users to upload and manage documents, preview extraction results, and quiz through the visual interface after local deployment. In the knowledge question and answer session, the system not only shows the final answer, but also presents the reasoning process, thus enhancing the transparency and interpretability of the whole question and answer process. Through this product interface, users can use KAG more intuitively and easily

Version 0.5 (2024-10-25)

检索增强生成（RAG）技术推动了领域应用与大模型结合。然而，RAG 存在着向量相似度与知识推理相关性差距大、对知识逻辑（如数值、时间关系、专家规则等）不敏感等问题，这些都阻碍了专业知识服务的落地。10 月 25 日，OpenSPG 发布 V0.5 版本，正式发布了知识增强生成（KAG）的专业领域知识服务框架

版本亮点

1. KAG 专业领域知识服务框架

KAG 旨在充分利用知识图谱和向量检索的优势，并通过四个方面双向增强大型语言模型和知识图谱，以解决 RAG 挑战
(1) 对 LLM 友好的语义化知识管理
(2) 知识图谱与原文片段之间的互索引
(3) 逻辑符号引导的混合推理引擎
(4) 基于语义推理的知识对齐
KAG 在多跳问答任务中显著优于 NaiveRAG、HippoRAG 等方法，在 hotpotQA 上的 F1 分数相对提高了 19.6%，在 2wiki 上的 F1 分数相对提高了33.5%

2. 知识库管理

OpenSPG针对KAG 还提供了一个用户友好的产品界面，支持用户在本地部署后，通过可视化界面进行文档上传和管理、预览抽取结果、以及知识问答。在知识问答环节，系统不仅展示最终答案，还会呈现推理过程，从而增强了整个问答流程的透明度和可解释性。通过这个产品界面，用户能够更直观、更轻松地上手使用 KAG

Version 0.0.3

Version 0.0.3 (2024-08-15)

Knowledge graphs have become a crucial bridge between LLMs and AI Agents. the OpenSPG project officially released its first stable version. This release not only inherits all the powerful features of the previous beta version but also brings comprehensive improvements in stability, compatibility, and user experience, aiming to provide a more mature and reliable knowledge construction solution for enterprises and developers.

Highlights of the Release Version:

1. Unified Knowledge Extraction with LLMs

The first stable version of OpenSPG inherits and optimizes the unified knowledge extraction feature from the beta version.
This feature is based on OneKE, a Chinese-English bilingual knowledge extraction grand model jointly released by Ant Group and Zhejiang University. Through techniques like hard negative sampling and schema-rotation-based instruction construction, it enhances the generalization capability of structured information extraction.

2. Product Visualization Interface

The release further strengthens the visualization interface, offering users a more intuitive data exploration and analysis experience. You can now visually inspect modeling results on the page and conduct interactive analysis and reasoning queries.

3. Continuous Optimization and Bug Fixes

Bugfix 1: Initialization exception in knext builder (issue #236 #246)
Bugfix 2: Fixed error in reasoner transform ListOpExpr (#328)
Bugfix 3: Front-end canvas display issue in analysis reasoning (Issue #269)

The release version of OpenSPG is applicable to multiple domains, including but not limited to financial risk control, healthcare, enterprise knowledge management, and intelligent customer service. By constructing high-quality knowledge graphs, it empowers various application scenarios such as decision analysis, recommendation systems, and natural language understanding.

Version 0.0.3 (2024-08-15)

知识图谱已成为连接大模型与智能体的重要桥梁。OpenSPG 项目正式发布首个 Release 版本。这一版本承袭了此前 beta 版本的所有强大功能，在稳定性、兼容性和用户体验方面进行了全面提升，旨在为企业和开发者提供更加成熟可靠的知识构建解决方案。

版本亮点

1. 大模型统一知识抽取
