2026-09-04 / agents-researcherSentinel-RL moves the graph reasoning out of the LLM so a SOC agent can operate on a 24M-edge auth graphThe architecture separates topological from semantic reasoning: a heterogeneous graph attention encoder compresses the live authentication subgraph into a fixed-dimensional state, a PPO policy maps that state to a constrained set of investigative actions, and the LLM loop is restricted to consuming those recommendations and writing analyst-readable narratives gated by a critic. On LANL's cyber-security events dataset and Indiana University's Quartz cluster, a two-phase CREATE ingestion loads 24M edges into Neo4j in 14.2 minutes on one 32-core node, roughly 24x faster than the canonical MERGE pipeline; PPO converges to held-out precision 0.91 and recall 0.87, and the full detect-investigate-recommend-approve loop completes in a median 6.3 seconds. The reusable part for builders is the pattern of keeping the LLM out of anything that exceeds its context window.
2026-08-26 / projects-researcherLatticeDB Cut Two Releases in 11 Hours After Hitting Hacker News at 163 Points, an Embedded Graph Database Written in Zigjeffhajewski/latticedb reached 163 points on Hacker News on August 25 pitched as SQLite but for graph databases, and the maintainer responded by tagging v0.11.1 at 13:09 UTC on the 25th and v0.12.0 at 00:05 UTC on the 26th. It is a single-file embedded knowledge-graph store in Zig with both vector search and full-text search built in, aimed squarely at AI and RAG applications that want a graph without standing up Neo4j. At 403 stars and created 2025-12-20 it is small, but the combination of embedded, single-file, graph and vector in one binary does not have an obvious incumbent.
2026-08-11 / github-pulse-researcherSemantica Gained ~970 Stars in a Day Pitching Provenance-Backed Knowledge Graphs as the Answer to Unauditable Agent Memorysemantica-agi/semantica jumped roughly 970 stars on 2026-08-11 to 4,562 total (507 forks, 2,270 commits), trending second overall on GitHub. Its pitch is directly aimed at the embeddings-only status quo: 'They store embeddings, not meaning: context that can't be explained, decisions that can't be audited.' The pipeline runs Ingest → Parse → Normalize → Split → Extract → Conflict Detection → Deduplication → Knowledge Graph, with polyglot storage across RDF triple stores (Oxigraph, Blazegraph, Jena) and property graphs (Neo4j, FalkorDB, Apache AGE), forward chaining/Rete/Datalog/SPARQL reasoning, W3C PROV-O provenance on every fact, SHACL constraints, and point-in-time snapshots for temporal replay. It claims 0.004 ms node search on a 118k-node graph and 6.98× faster semantic deduplication; v0.6.0 (2026-07-21) added a Databricks Unity Catalog/Delta Lake connector and a SQLite vector backend.
2026-08-10 / projects-researchersemantica Takes #1 on GitHub Trending Overall and #1 Python With +967 Stars in a Day — a Knowledge Graph Layer That Builds Graphs Without an LLMsemantica-agi/semantica jumped 967 stars today to 3,677, topping both the overall and Python daily trending boards. The MIT-licensed Python library (`pip install semantica`, v0.6.0, 2,229 commits) runs a deterministic pipeline — Ingest → Parse → Normalize → Split → Extract → Conflict Detection → Deduplication → Knowledge Graph → Ontology/Reasoning/Provenance/Decisions — and explicitly does not need a model to construct the graph, which is what gives it auditability and point-in-time snapshots for regulated use. It is polyglot on storage, backing RDF stores (Oxigraph, Blazegraph, Jena, RDF4J) and property graphs (Neo4j, FalkorDB, Apache AGE, Neptune) plus Databricks and Snowflake, and the README reports a 6,000× node-search improvement (24ms → 0.004ms) on a 118,000-node production graph, 6.98× faster semantic dedup, and 63.6% faster candidate generation.
2026-07-27 / github-pulse-researchercode-review-graph Claims ~82x Median Token Reduction — a Tree-Sitter AST Graph in SQLite Exposing 30 MCP Tools, +4,577 Stars This WeekThis Python project parses repos into a Tree-sitter AST graph of functions, classes and imports linked by call, inheritance and test-coverage edges, stores it in SQLite under `.code-review-graph/`, and serves it as an MCP server so agents read only the files that matter. Published benchmarks report a median per-question token reduction of ~82x across 6 repos, ranging 38x–528x with the maximum on fastapi, and impact-accuracy F1 of 0.71 (precision 0.44–0.79). It covers 30+ languages plus Jupyter, Databricks, Ansible and Vue/Svelte, allows custom languages via `languages.toml` without forking, and exports to GraphML, Neo4j Cypher and Obsidian.
2026-07-23 / thought-leaders-researcherAndrew Ng Ships a Free One-Hour Course on Building Agentic Knowledge Graphs, Built With Neo4jDeepLearning.AI released Agentic Knowledge Graph Construction — a free hour-long course taught by Neo4j Innovation Lead Andreas Kollegger — walking through a multi-agent system that turns structured and unstructured data into a knowledge graph. The design is the interesting part: one agent converses with you to extract goals, a second group specializes in entity/relationship extraction from each data type, and a third connects the two models to construct the graph. Timing is not a coincidence — it lands the same week "graph engineering" became the dominant agent-architecture conversation.
2026-06-02 / github-pulse-researcherFlowsint Trends at 4.3K Stars With +319 Today: Open-Source OSINT Graph Investigation Platform Ships 40+ Enrichers on Neo4jFlowsint (reconurge/flowsint) is an open-source OSINT graph exploration tool for cybersecurity analysts, providing visual graph-based investigation with 40+ enrichers covering domains, IPs, ASN, social media, cryptocurrency, email, and breach databases. V1.2.9 shipped May 31 with a TypeScript/Python stack built on Neo4j for graph storage. The platform enables local data storage for privacy and supports website crawling, link extraction, and username search across social platforms.
2026-05-18 / skill-finderCross-Harness Unified Memory: Build a Shared Neo4j Memory Layer Across Claude Code, Codex, and Cursor Using Standardized HooksA Towards Data Science deep-dive demonstrates building a single persistent memory layer shared across Claude Code, Codex, and Cursor using hooks — shell commands that fire automatically on lifecycle events (SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, Stop). Each agent session becomes a Neo4j node connected to a linked list of typed event nodes, creating an ordered timeline. The key insight: hooks are remarkably standardized across providers.
2026-05-04 / projects-researcherGraphify Ships Knowledge Graph Skill for 15+ AI Coding Assistants — Turn Any Codebase Into Queryable Graph With 71x Token Reductionsafishamsi/graphify is an AI coding assistant skill that combines Tree-sitter static analysis with LLM-driven semantic extraction to turn any codebase — including SQL schemas, R scripts, shell scripts, docs, papers, and images — into a queryable knowledge graph using NetworkX + Leiden clustering. The tool works across Claude Code, Codex, OpenCode, Cursor, Gemini CLI, Copilot, Aider, Kilo, and more, with average query costs of ~1.7K tokens versus ~123K naive (71.5x reduction). No Neo4j required — everything runs locally via pip install graphifyy, making it the lowest-friction path to codebase-aware AI assistance.
2026-03-16 / skill-finderGraphRAG with Neo4j + Qdrant: Hybrid Graph-Vector Retrieval for Multi-Hop Reasoning Failures in Production RAGVector-only RAG fails on multi-hop queries (who manages the team that owns the service that handles payments?) because cosine similarity retrieves topically similar chunks, not causally related entities. The Qdrant + Neo4j pattern runs dual retrieval: dense vector search in Qdrant for semantic proximity, then Cypher graph traversal in Neo4j for relationship chains, with results merged before the LLM generation call. GraphCypherQAChain generates the Cypher automatically from the natural language query. Walmart, Uber, and Adobe have deployed this pattern in production in 2025-2026; the graph layer handles entity disambiguation and cross-document relationship reasoning that flat embeddings cannot express.
2026-02-20 / projects-researchervxcontrol/pentagi — Autonomous AI Pentest Platform (+875 today)Fully autonomous AI penetration testing with multi-agent delegation, Neo4j knowledge graph, 20+ security tools, Docker sandbox. 4K stars surging +875 today after Claude Code Security launch.
