Memgraph 3.0 Is Out: Solve the LLM Context Problem

Status and Journey

Memgraph 2.0 was launched in 2021 and was a huge success—hundreds of thousands of downloads, thousands of community members, and dozens and dozens of customers needing speed and are excited to benefit from the most performant graph database on the market.

Since then, we’ve been on a relentless journey to refine Memgraph. Between 2.0 and 3.0, we focused on three key areas:

  • Ease of use. Making Memgraph more intuitive with better tooling, documentation, and integrations.
  • Enterprise-focused features. Bringing robust access control, advanced security, and high-availability options.
  • Performance optimization. Pushing the limits of query speed, memory efficiency, and large-scale graph handling.

Now, Memgraph 3.0 is here to take things further. While graph analytics remains a core use case, we’ve also evolved to meet new demands in AI, real-time processing, and intelligent decision-making. Whether you're handling 1000+ reads and writes per second or integrating with AI-driven systems, Memgraph continues to deliver unmatched speed and flexibility.

AI Age: LLM Limitations and Context Problem

However, the age of AI is here. AI and LLMs are taking the world by storm, and we are at the beginnings of enormous economic enablement across industries powered by Chatbots and Agents. For apps to be useful, they need to be personalized and tailored to the user, with the right context. Otherwise, they are general.

Unfortunately, LLMs have clear limitations, most notably the context window. Enterprise data and knowledge bases that users want to query are many orders of magnitude larger than the size of the context window. They cannot do that as they cannot process vast datasets without losing precision or hallucinating.

So, if AI is going to live up to its potential for the Enterprise, it needs better context. That's the problem that Memgraph 3.0 solves. Memgraph brings the most relevant information from your Enterprise datasets to the context window.

GraphRAG As a Key Building Block

By being the context engine, Memgraph makes personalized GenAI apps possible. It does it through GraphRAG. Memgraph GraphRAG architecture overview

In a nutshell, GraphRAG uses the power of knowledge graphs to improve the recall and precision of retrieval-augmented generation (RAG) systems. Instead of just scraping the surface, GraphRAG dives deep into your knowledge graph to extract accurate, contextually relevant insights, minimize hallucinations, and deliver answers grounded in your proprietary data. But sometimes, you want to be able to skim through and search based on similarity across vast swathes of unstructured data.

In such use cases, that’s when vectors come in. With vector search, you can now combine graph-based graph-based reasoning with dense vector representations of unstructured data—like documents, embeddings, and LLM-generated knowledge. Graphs and vectors are a perfect match: graphs provide explicit relationships, while vectors encode semantic similarity. Together, they create a powerful retrieval layer, enabling multi-hop reasoning, fast similarity search, and dynamic context refinement.

With Memgraph’s in-memory graph database as the context engine at its core, GraphRAG integrates knowledge graphs, advanced dynamic algorithms, and user intent from LLMs to enable developers to create chatbots and agents with the most relevant information fed into the context window.

So, What’s New in 3.0?

Vector search is now a core feature: Memgraph 3.0 introduces vector search, enabling similarity and relevance-based graph search in a unified system. This feature is perfect for pinpointing the most relevant nodes in your knowledge graph.

GraphChat gets smarter in Memgraph Lab 3.0: We’ve done major updates to GraphChat in Memgraph Lab (with dark mode now). You don’t need to be a Cypher expert to unlock the full potential of your data. Just ask a question in plain English, and GraphChat will convert it into a Cypher query, run it, and give you the best possible answer—grounded in the context of your knowledge graph. No more guessing, no more approximations, just answers that make sense. With the rise of DeepSeek, Memgraph Lab now supports adding DeepSeek models and connections to GraphChat.

Performance & reliability improvements: The latest update also significantly improves performance and reliability. Replication recovery has been optimized for more efficient failover handling, ensuring greater system resilience. Query execution is now faster, with improved abort times and better performance under load. Additionally, Memgraph 3.0 includes security updates, such as updated Python libraries in the Docker package, to enhance overall system safety.
