A few challenges We keep redoing what has already been done elsewhere in the company. We don’t learn from our mistakes.

Introducing FACT: Fast Augmented Context Tools (3.2x faster, 90% cost reduction vs RAG) RAG had its run, but it’s not built for agentic systems. Vectors are fuzzy, slow, and blind to context. They work fine for static data, but once you enter recursive, real-time workflows, where agents need to reason, act, and reflect. RAG collapses under its own ambiguity. That’s why I built FACT: Fast Augmented Context Tools. Traditional Approach: User Query → Database → Processing → Response (2-5 seconds) FACT Approach: User Query → Intelligent Cache → [If Miss] → Optimized Processing → Response (50ms) It replaces vector search in RAG pipelines with a combination of intelligent prompt caching and deterministic tool execution via MCP. Instead of guessing which chunk is relevant, FACT explicitly retrieves structured data, SQL queries, live APIs, internal tools, then intelligently caches the result if it’s useful downstream. The prompt caching isn’t just basic storage. It’s intelligent using the prompt cache from Anthropic and other LLM providers, tuned for feedback-driven loops: static elements get reused, transient ones expire, and the system adapts in real time. Some things you always want cached, schemas, domain prompts. Others, like live data, need freshness. Traditional RAG is particularly bad at this. Ask anyone force to frequently update vector DBs. I'm also using Arcade.dev to handle secure, scalable execution across both local and cloud environments, giving FACT hybrid intelligence for complex pipelines and automatic tool selection. If you're building serious agents, skip the embeddings. RAG is a workaround. FACT is a foundation. It’s cheaper, faster, and designed for how agents actually work: with tools, memory, and intent.

RAG vs Graph RAG, explained visually. (it's a popular LLM interview question) Imagine you have a long document, say a biography, about an individual (X) who has accomplished several things in this life. ↳ Chapter 1: Talks about Accomplishment-1. ↳ Chapter 2: Talks about Accomplishment-2. ... ↳ Chapter 10: Talks about Accomplishment-10. Summarizing all these accomplishments via RAG might never be possible since... ...it must require the entire context... ...but one might only be fetching the top-k relevant chunks from the vector db. Moreover, since traditional RAG systems retrieve each chunk independently, this can often leave the LLM to infer the connections between them (provided the chunks are retrieved). Graph RAG solves this. The idea is to first create a graph (entities & relationships) from the documents and then do traversal over that graph during the retrieval phase. See how Graph RAG solves the above problems. - First, a system (typically an LLM) will create the graph by understanding the biography. - This will produce a full graph of nodes entities & relationships, and a subgraph will look like this: ↳ X → → Accomplishment-1. ↳ X → → Accomplishment-2. ... ↳ X → → Accomplishment-N. When summarizing these accomplishments, the retrieval phase can do a graph traversal to fetch all the relevant context related to X's accomplishments. This context, when passed to the LLM, will produce a more coherent and complete answer as opposed to traditional RAG. Another reason why Graph RAG systems are so effective is because LLMs are inherently adept at reasoning with structured data. Graph RAG instills that structure into them with their retrieval mechanism. 👉 Over to you: What are some other issues with traditional RAG systems that Graph RAG solves? ____ Find me → Avi Chawla Every day, I share tutorials and insights on DS, ML, LLMs, and RAGs. | 24 comments on LinkedIn

Audience: This blog is written for engineering leaders, architects, and decision-makers who want to understand what a knowledge graph is, when it makes sense, and when it doesn’t. It is not a deep technical dive, but a strategic overview.

A serious knowledge graph effort is much more than a bit of Github, but customers and adventurous minds keep asking me if there is an easy to use (read: POC click-and-go solution) graph RAG open source stack they can use to generate knowledge graphs. So, here is my list of projects I keep an eye on. Mind, there is nothing simple if you venture into graphs, despite all the claims and marketing. Things like graph machine learning, graph layout and distributed graph analytics is more than a bit of pip install. The best solutions are hidden inside multi-nationals, custom made. Equity firms and investors sometimes ask me to evaluate innovations. It's amazing what talented people develop and never shows up in the news, or on Github. TrustGraph - The Knowledge Platform for AI https://trustgraph.ai/ The only one with a distributed architecture and made for enterprise KG. itext2kg - https://lnkd.in/e-eQbwV5 Clean and plain. Wrapped prompts done right. Fast GraphRAG - https://lnkd.in/e7jZ9GZH Popular and with some basic visualization. ZEP - https://lnkd.in/epxtKtCU Geared towards agentic memory. Triplex - https://lnkd.in/eGV8FR56 LLM to extract triples. GraphRAG Local with UI - https://lnkd.in/ePGeqqQE Another starting point for small KG efforts. Or to convince your investors. GraphRAG visualizer - https://lnkd.in/ePuMmfkR Makes pretty pictures but not for drill-downs. Neo4j's GraphRAG - https://lnkd.in/ex_A52RU A python package with a focus on getting data into Neo4j. OpenSPG - https://lnkd.in/er4qUFJv Has a different take and more academic. Microsoft GraphRAG - https://lnkd.in/e_a-mPum A classic but I don't think anyone is using this beyond experimentation. yWorks - https://www.yworks.com If you are serious about interactive graph layout.

1. Introduction: A Tension in Knowledge Representation The classic definition by Thomas Gruber—"an ontology is a formal, explicit specification of a shared conceptualization"—has long served as a foundational reference in knowledge representation.

LLMs generate possibilities; knowledge graphs remember what works. Together, they forge the recursive memory and creative engine that enables AI systems to truly evolve themselves. Combining neural components (like large language models) with symbolic verification creates a powerful framework for self-evolution that overcomes limitations of either approach used independently. AlphaEvolve demonstrates that self-evolving systems face a fundamental tension between generating novel solutions and ensuring those solutions actually work. The paper shows how AlphaEvolve addresses this through a hybrid architecture where: Neural components (LLMs) provide creative generation of code modifications by drawing on patterns learned from vast training data Symbolic components (code execution) provide ground truth verification through deterministic evaluation Without this combination, a system would either generate interesting but incorrect solutions (neural-only approach) or be limited to small, safe modifications within known patterns (symbolic-only approach). The system can operate at multiple levels of abstraction depending on the problem: raw solution evolution, constructor function evolution, search algorithm evolution, or co-evolution of intermediate solutions and search algorithms. This capability emanates directly from the neurosymbolic integration, where: Neural networks excel at working with continuous, high-dimensional spaces and recognizing patterns across abstraction levels Symbolic systems provide precise representations of discrete structures and logical relationships This enables AlphaEvolve to modify everything from specific lines of code to entire algorithmic approaches. While AlphaEvolve currently uses an evolutionary database, a knowledge graph structure could significantly enhance self-evolution by: Capturing evolutionary relationships between solutions Identifying patterns of code changes that consistently lead to improvements Representing semantic connections between different solution approaches Supporting transfer learning across problem domains Automated, objective evaluation is the core foundation enabling self-evolution: The main limitation of AlphaEvolve is that it handles problems for which it is possible to devise an automated evaluator. This evaluation component provides the "ground truth" feedback that guides evolution, allowing the system to: Differentiate between successful and unsuccessful modifications Create selection pressure toward better-performing solutions Avoid hallucinations or non-functional solutions that might emerge from neural components alone. When applied to optimize Gemini's training kernels, the system essentially improved the very LLM technology that powers it. | 12 comments on LinkedIn

I added a Knowledge Graph to Cursor using MCP. You gotta see this working! Knowledge graphs are a game-changer for AI Agents, and this is one example of how you can take advantage of them. How this works: 1. Cursor connects to Graphiti's MCP Server. Graphiti is a very popular open-source Knowledge Graph library for AI agents. 2. Graphiti connects to Neo4j running locally. Now, every time I interact with Cursor, the information is synthesized and stored in the knowledge graph. In short, Cursor now "remembers" everything about our project. Huge! Here is the video I recorded. To get this working on your computer, follow the instructions on this link: https://lnkd.in/eeZ_4dkb Something super cool about using Graphiti's MCP server: You can use one model to develop the requirements and a completely different model to implement the code. This is a huge plus because you could use the stronger model at each stage. Also, Graphiti supports custom entities, which you can use when running the MCP server. You can use these custom entities to structure and recall domain-specific information, which will tenfold the accuracy of your results. Here is an example of what these look like: https://lnkd.in/efv7kTaH By the way, knowledge graphs for agents are a big thing. A few ridiculous and eye-opening benchmarks comparing an AI Agent using knowledge graphs with state-of-the-art methods: • 94.8% accuracy versus 93.4% in the Deep Memory Retrieval (DMR) benchmark. • 71.2% accuracy versus 60.2% on conversations simulating real-world enterprise use cases. • 2.58s of latency versus 28.9s. • 38.4% improvement in temporal reasoning.

𝙏𝙝𝙤𝙪𝙜𝙝𝙩 𝙛𝙤𝙧 𝙩𝙝𝙚 𝘿𝙖𝙮: What if we could encapsulate everything a person knows—their entire bubble of knowledge, what I’d call a Personal Knowledge Domain or better, our 𝙎𝙚𝙢𝙖𝙣𝙩𝙞𝙘 𝙎𝙚𝙡𝙛, and represent it in an RDF graph? From that foundation, we could create Personal Agents that act on our behalf. Each of us would own our agent, with the ability to share or lease it for collaboration with other agents. If we could make these agents secure, continuously updatable, and interoperable, what kind of power might we unlock for the human race? Is this idea so far-fetched? It has solid grounding in knowledge representation, identity theory, and agent-based systems. It fits right in with current trends: AI assistants, the semantic web, Web3 identity, and digital twins. Yes, the technical and ethical hurdles are significant, but this could become the backbone of a future architecture for personalized AI and cooperative knowledge ecosystems. Pieces of the puzzle already exist: Tim Berners-Lee’s Solid Project, digital twins for individuals, Personal AI platforms like personal.ai, Retrieval-Augmented Language Model agents (ReALM), and Web3 identity efforts such as SpruceID, architectures such as MCP and inter-agent protocols such as A2A. We see movement in human-centric knowledge graphs like FOAF and SIOC, learning analytics, personal learning environments, and LLM-graph hybrids. What we still need is a unified architecture that: * Employs RDF or similar for semantic richness * Ensures user ownership and true portability * Enables secure agent-to-agent collaboration * Supports continuous updates and trust mechanisms * Integrates with LLMs for natural, contextual reasoning These are certainly not novel notions, for example: * MyPDDL (My Personal Digital Life) and the PDS (Personal Data Store) concept from MIT and the EU’s DECODE project. * The Human-Centric AI Group at Stanford and the Augmented Social Cognition group at PARC have also published research around lifelong personal agents and social memory systems. However, one wonders if anyone is working on combining all of the ingredients into a fully baked cake - after which we can enjoy dessert while our personal agents do our bidding. | 21 comments on LinkedIn
