Cognee is an open-source knowledge engine that gives AI agents persistent, learning memory without requiring you to architect a graph database from scratch. Under the hood it combines a vector store, a graph database (Neo4j), and semantic indexing into a single interface backed by four simple operations: remember, recall, forget, and improve. The magic is in the auto-routing recall layer. Rather than forcing developers to choose between similarity search and structured graph traversal, Cognee analyzes the query and picks the optimal strategy automatically. Session memory syncs to permanent graphs in the background, so agents accumulate knowledge across runs without any manual persistence logic. At 15k stars and growing fast, Cognee is quietly becoming the memory layer developers reach for when building agents that need to reference past work — think support bots, research pipelines, coding agents that shouldn't forget what a codebase looks like. It deploys on PostgreSQL with pgvector, integrates with OpenAI and Claude, and ships with Docker configs for Railway, Fly.io, and Render.

Holo3 is a vision-language model built specifically for GUI agents — AI that can see and interact with web browsers, desktop apps, and mobile UIs. Developed by H Company, the 35B-A3B mixture-of-experts variant scores 78.85% on OSWorld-Verified, the most rigorous benchmark for autonomous computer use, edging out GPT-5.4 Thinking and Claude Opus 4.6 while reportedly costing 10x less to run. The model architecture separates GUI understanding from action planning using a sparse MoE design, enabling high accuracy with a much smaller active parameter footprint. It supports point-and-click, scroll, type, and multi-step workflows across all major OS environments. Weights for the 35B-A3B variant are released under Apache 2.0, while a free-tier API is available at hub.hcompany.ai. H Company is a Paris-based AI startup founded by former DeepMind researchers. Holo3 is their bet that purpose-built specialist models will outperform general-purpose frontier LLMs on narrow, high-value verticals — and the OSWorld leaderboard suggests they're winning that bet for now.
Reviewer scorecard
“Six lines of code for persistent knowledge graph memory across agent sessions? That's a genuinely useful abstraction. The auto-routing recall that picks the right search strategy (vector vs. graph) without manual tuning removes a real pain point. PostgreSQL + pgvector backend means you're not locked into a proprietary store. I'm integrating this into my next agent project.”
“Topping OSWorld-Verified while being open-source and cheap to run is a genuinely rare combination. If you're building any kind of browser automation or desktop agent pipeline, this is the model to benchmark against first. The free API tier lowers the barrier to try it immediately.”
“Another 'knowledge graph for AI' library in a space already crowded with Mem0, LlamaIndex memory, LangChain's entity store, and MemGPT. The 'six lines of code' promise falls apart when you need custom ingestion pipelines or production-grade tenant isolation. PostgreSQL + Neo4j + vector store is three moving parts for what often just needs a good retrieval strategy. Wait for the ecosystem to consolidate.”
“OSWorld numbers are impressive, but benchmarks and real-world reliability are very different things. GUI agents still struggle with dynamic content, CAPTCHAs, login flows, and anything that deviates from the training distribution. H Company is a small startup — unclear if they can keep pace with OpenAI/Anthropic iteration cycles.”
“Memory is the missing layer in the agent stack. Cognee's cognitive science-inspired architecture — remember, recall, forget, improve — maps remarkably well to how useful agents should work. The feedback loop that improves future responses is the critical piece. As agents run longer and longer tasks, systems like this become the connective tissue that makes them actually reliable.”
“GUI agents are the missing layer for true software automation. A model that can reliably use any desktop app or web interface without APIs is transformative for enterprise workflow automation. The fact that a small European team is leading the OSWorld benchmark signals that vertical AI specialists are a real competitive force in 2026.”
“If I'm building a research assistant or a content pipeline that needs to reference past projects, having persistent memory that actually understands relationships (not just semantic similarity) changes the game. The fact it supports multimodal ingestion means I can throw PDFs, notes, and transcripts at it without preprocessing gymnastics.”
“As someone who constantly switches between design tools, browser previews, and CMS dashboards — a reliable GUI agent would be genuinely life-changing. Holo3's ability to handle multi-step UI workflows without brittle selectors or fragile Playwright scripts is what makes this interesting beyond the benchmark numbers.”
